Thanks for taking the time to explain how chemical injectors work and how to isolate the issue to repair the problem. Best explanation I have been looking for.
Thank you, thank you, thank you !!! for your detailed explanation on PW chemical injection system. Got home from work this morning and did you step by step…… got it working! Thank you
Brian, you get 5 stars. Walking the viewers step by step on things to look for and the why, it was just an incredible lesson. Many thanks for sharing your knowledge
Brian, thank you for putting this video together! This really helped me in troubleshooting my issue and it seems a quick buy of 100 foot quarter inch hose is causing some back pressure. I swapped to the original 20 foot it started siphoning chemical. It is stated online that with a 2700 psi pressure washer if I go over 60 foot it will most likely stop the chemical to siphon though. I will go with a 50 foot 3/8 hose and try again.
I had the same exact problem. I have a 3.2GPM with 100’ of 3/8 hose, no draw. Switch to the stock hose and got my draw back. Kinda annoying to switch hose between soak and rinse, but I figured it out.
Great video Brian. I have never heard it explained in this manner. I bought a new 2.1 gpm injector that works over my house, but did not work over my neighbors house across the street, your explains why I was having that problem. I started using the new injector because after couple years of use the one on the pump stopped working. I bought a nonadjustable replacement injector, but it did not work. So I suspect there might be corrosion internally on the pump side fixed portion. I usually use 10% sodium hypochlorite bleach. I am reminded now to always clean out the line with clean water after use because I noticed that the filter on the end of the tube corroded badly.
Good explanation bud. As a seasoned pressure washer of 30 years, I do know you will find a ¾" water hose will allow more water flow for the allowance for the injector to work properly.
You are correct. I have found that the flood of "discount" hoses that list 3/4" are reduced to 1/2" where the fittings are attached. Most guys never realize it. But a good 3/4" is a little pricey and they don't want to spend that money. Doesn't make sense sometimes.
Thank you so much Brain. I had no idea how this injector worked. Very good pressure washer chemical injector lesson 101. I only wish I'd tuned in before I messed up I think; but you be the judge. Tried to do a powerwash for a relative but wasn't getting any chemical. I've only used the washer twice and it worked fine at my place (3+yrs ago). Took the injector nozzle off to see if it was clogged unaware of the steel ball and spring. I didn't see any loose parts, but when I reinstalled the nozzle and started the pump, I got a geyser OUT of the nozzle. If this I/M45810D.2, 2.3GPM, 2600PSI model has the inner workings as you describe, I probably flushed them out into the grass. Also my relative had a smallish water hose, maybe 1/2 inch dia and the coupling at her townhouse water supply had an unstoppable leak. Lost quit a bit of volume there the but pressure felt adequate. I'll hook the pump up at home and see if it draws chemical but if you could look at this model# (purposely left manufacture's name out of this post but if you think "Metal", I'm sure you know who makes it, begins with an "I") to see if there is any thing else that could have failed as a result of the geyser. The design spec sheet show an "O" ring, cone spring, steel ball, a smaller "O" ring and hose barb (nozzle I've called it). I saw none of this when I removed the nozzle/hose barb. Kit #8 should include the afore mentioned parts. Do you think this will get it back up and injecting chemicals? So sorry for such a long post but maybe it can help someone else as well.
@@Brian_the_repair_guy Thanks Brian. I assumed as much. There are 2 kits. #8 includes the items mentioned in the previous post. Kit #9 includes parts downstream of Chemical barb adapter to the pressure hose connection. Do you think I may need these? Or could it have been a water volume issue all along and I messed up when I took the Barb adapter off.
Wow, what a thorough and informative video. Thank you so much brother. There are so many pressure washing videos on TH-cam, most don't come close to being as helpful as this one is. Cheers!
So do you block the built on injector chemical hose off & use the new chemical hose correct? I have a issue where water is coming through my chemical hose & it take a minute to come out. I have the same exact injector for my 2.4gpm simpson, brand new. Took it apart, lubed everything from wand to pump to tank. chemicals wont feed with black tip in gun.
So why is water going building through my chemical hose? Would the check valves have anything to do with it? Water pressure is fine it's just the saop dispenser
I took off the injector and it was packed solid probably with calcium or hardened soap and will need to be replaced. Is it likely that the “mixer” (or whatever is in the adjoining part) also has this impacted material? I appreciate the way you explained things in the video, so I figured you understand the workings of the mixer as well. Thank you. Jon
@@JonFish-lg3yw any part from the injector out to the gun has the possibility to have this build up. Anything behind the injector should not have build up, unless the water itself is heavy in minerals
I just had this problem. Had to break out the pump sprayer. First thing I noticed was the customers water flow was weak. I'm gonna test it now with my supply, but I knew that was the problem. You confirmed it.
I’m hoping you can help me. I bought a 4200 PSI 4.0 DeWalt belt driven with a Honda engine and a Cat pump about 2 years ago and never used it. I pulled it out today for the first time and it’s not picking up chemicals. I’m getting over 5 gallons per minute ( overflowed a 5 gallon bucket in 43 seconds ). I took it apart and the ball and spring are not stuck and freely moving. The arrow is pointing out. Everything looks great it just isn’t picking up the chemicals. Do you have any other ideas I can try?
Make sure you are using the correct tip. Disconnect the pressure hose from the machine and run it with water and see if the chemical injector pulls with NO pressure hose.
So do you have both chemical injectors attached? Or do you plug one suction and use the quick connection one? Idk I need to know if you are using 1 or both on the machine
Thanks, getting no chemical out using what seems to be the same adjustable external injector, but my machine is built with a built in injector that would inject IN the pump, which I do not want to use. So trying to use this external injector leaving the built-in one unused, would this explain why I do not have any chemical going out ? Should I block the entry of the built-in one for the external unit to work !? Any advise would be appreciated, Thanks !
Thank you so much! By watching this video, I realized what you said and showed makes perfect sense. Now, I need to take mine apart and start over bc I did everything backwards 🤣🤣🤣
Cheers dude 😂 adjustable unloaded answered my question . Would the detergent applicator be ok to use with a good car was detergent or would a snow foam cannon be better job?
I have a question, and thank you for the video, I have the same set up as you in this video on my 3.2 GPM and I want to use my down stream injector (same as yours) rather than the stock injector (same location as yours). Can I cap off the stock injector to use only my down stream injector??? Reason I’m doing this is I’m running hot SH mixes sometimes and I do not want any back flow going into pump at all as that will destroy the pump. I will also be upgrading machine in future (8 GPM belt) and would rather keep the same set up. Thank you if you or anybody else can respond.
Great explanation. I have that same injector and it is brand new as is the 5 gpm 3000 psi machine. I used it one day and started having trouble with the ball getting stuck in it's o ring seat. I am very mechanically inclined and have taken it apart several times now. What is weird is that when I throttle down the machine and the flow and pressure drop it sucks like you know what!. If I throttle it wide open the ball gets jammed in the O ring from back pressure I guess and stops sucking. I am only running 100' of brand new hose. everything is sized correctly and is brand new. The ball itself to me feels like it is not perfectly round from the factory. Now I did over tighten the adjustment collar thinking it was loose the first day i used it. not realizing it was an adjustable metering thing, I thought oh crap I need to tighten this up so I did with small channel locks but I don't think it was enough to damage the O ring. But I think it likes to get stuck really easy when the pressure goes up now. Have you seen this problem or just replaced the O ring seat before? Any thoughts would be appreciated Thank You!!
thanks very much for the explanation. You mention that the ball bearing should be free ..moving around. mine does not move. i tried pb blaster and wd 40 to free it.. any other suggestions to free the ball?.
Brian, what would cause the water to flow backwards, thru the downstream injector, into the 5 gal bucket where the SH is? This happens to me now n then.
_Hey what do you think would cause my injector to suck water back into my 5gal bucket vs. pulling the chemical out like it should? It's not installed backwards either & I've cleaned the ball & spring yesterday with wd40 I'm frustrated now.._
Hi Brian, Thanks for the helpful video. I connected an injector to my Simpson 2.5 GPM machine. A strange thing happened. The pressure of the water through the injector without the machine running caused a narrow jet like spray with no chemicals. When I stopped the flow with my thumb and released it the water came out like it would if it were from a detached garden hose.. but it was full of chemicals which tells me the injector is working. When I attached the pressure hose with the black/soap tip and the engine running no chemicals were produced. I’m lost as to what the problem is.
If chemicals are moving with no pressure hose and gun, but do not move with the pressure hose a d gun then typically the hose or gun is the problem. If they have build up or corrosion they restrict the flow and the injector will not work properly
Many thanks brilliant insight into the possible problems, I recently had a issue with water coming out of the chemical hose feeding back into the acid. Any ideas regarding this problem
Thank you for the Video. Where should I look when water is back feeding into my dispenser? I get soap when I have the trigger pressed but when I let off water goes into my soap dispenser.
Which inductor is better? The fixed one or the one that you can remove/turn off? I’ve had the fixed one on for a while and it seems like it always introduces air as opposed to being able to turn the valve off on the inductor to stop that…. What do you think about that?
I like the removable unit. They are usually rebuildable and if they stop working, they have a leak you can take them off so they don't pose a problem with the pressure
I just washed my first house today and I noticed that the injector really wasn't working all that great at all so I watch a video and as I told you from the beginning I'm a rookie I know nothing about power washers when I put my quick connects on I put it in the wrong direction the Earl is in the wrong direction thank you for the video I think you just fixed my injector problem
Really appreciate this video. Did the elimination steps, turns out it was the green flexible aftermarket hose. Put the OEM hose back on and it now siphons correct ly.
Great video Brian! can you leave the factory injector in place as is and quick connect your adjustable injector and use that to siphon the bleach while still leaving the factory injector in line unused with no siphon hose attached? Would the adjustable one still work properly with the factory 1 left open or Would you need to plug the siphon barb from adding air into the line?
Very helpful Brian. Thank you. I took my injection valve apart and unstuck the ball put it back together again but still my Simpson MSV3024 refuses to pull chemical :(
There are other reasons way it may not be working. Be sure to check everything listed in the video. If none of this fixes the problem rebuild or replace it
Thanks for your best tip.will you help me how to fix vibration of the machine at work. I check the 1. water flow in to the machine 2.I change all 6 water valves including the O ring. 3.I change the loader unloader from other machine of the same type the problem is not solved. 4.if I change all the water part and replace it by the same machine,it works properly. I can't fix the problem of its water part.please will you help me? Thank you
Hey Brian thankyou for helping me troubleshoot the issue. It's discouraging considering I just bought the Simpson Clean Machine 3400 PSI 2.5 GPM 4 months ago and have only used it twice. It seems to be the actual pump that's the issue, I have the spring, the ball, the water volume is good. When I took off the pressure hose and just had the water turned on it was not sucking any chemical. I only used it once before and it worked great. I am not sure what the issue is. Any thoughts would be greatly appreciated.
Your pump should not be an issue unless it has an obstruction. If you have 5gpm going to the pump and it is not producing chemical without the pressure hose on, then you would have an injector issue.
Fantastic video! Excellent explanation!! I’ve been searching TH-cam for basically 2 days and watched at least 25 or 30 videos trying to understand why my chemical injector works without the hose/wand attached, but stops drawing when attached. Side note: after disassembling the injector numerous times (at least 5 😂) I lost the spring! Time to cap it and get an external one.
I know it’s been a year but I’m really looking for your help. So I have a 4gpm with 4200 psi. And I use the fixed downstream injector. My chemical is being sucked up when I have the hose it came with which is 50ft. And I use it with a new gun I bought and works fine but when I put a different hose which is 100ft or even my 150ft hose the chemical does not get sucked out but hears the funny part I know in your vid you said it’s the hose but I think in my case it’s not because when I don’t have the gun the hose and the hose is just releasing the water through the ball valve the chemical then isss being sucked out but only when the ball valve is fully open. When I put the soap tip with the gun it ends up not working anymore. What is my problem?
Great detailed video! This is the problem I’ve run into. I have a Simpson 4000psi / 3.5gpm. Chemical injector stopped pulling chemical, so I put in a new one. Ive tried a bunch of things. When the water is on, but the machine is OFF, it will pull chemical. I tried it with and without the hose, gun, tip, etc. strong suction. When the machine is ON, the suction is very weak and will not pull chemical, regardless of hose, gun, tip, etc.
The volume of water, not pressure will dictate the flow of soap in the injector. You must use the black tip to allow the flow of soap. If there is no flow, then follow the direction in this video
Hi Brian, I have a NorthStar pressure washer 9hp 3GPM with a CAT 4SPX pump. The downstream chemical injector works with the wand and black tip but won't work when I attach the 18FT washer pole I also purchased (tip or no tip). I have had both of these for 10 years but never tried to spray chemical though the pole until today. I thought I may have too much hose so I connected the 18FT pole strait to the unit (no hose) and still won't siphon chemical. Any ideas?
This is typical. The addition of the pole changes the requirements for the injector to work properly. You can look for an injector that attaches at the end of the wand. I have seen guys put their injector at the connection between the gun and hose with success
Brian Shumack. Your explanation on how to trouble shoot a down loader is great! REALLY ! Yet, I am still having difficulties. I replaced my rusty cannon ball valve with a new one. I started my machine without the pressure washing hose attached and it drew chemical right away. Then, i attached just the pressure washing hose and again, it drew right away. Then, i attached the gun (without the tip) and again, it drew right away. Then, i installed the tip and everything stopped! No draw, no nothing. Could this be my gun is failing ?
It is possible one of a few things is occurring. If each thing is working up until the tip, I would suggest switching the hose or gun and see if there is a change. If you have a build up of corrosion in the hose or gun, the tip could allow just enough of the flow to be reduced so the injector fails. That would be the easiest thing to try first. Make sure the water is full pressure from the faucet and use no more than 50 feet of water hose. Let me know what you get. If this does not resolve the issue we will look at other possibilities.
What about if u have a new spring and ball, even tring a added injector but can't get any suction but can blow thru the injector, and water pressure is very good . Having troubles with 2 Dewalts, a 3800 and 3400psi series
1. You must be able to fill a 5 gallon bucket in a minute to insure you have enough water volume. 2. If the volume is good, hook 1 water hose to the pump, install injector, turn water on, turn engine on, see if you get chemical. If you do, then your pressure hose or gun is the issue. If you do not get chemical then the injector is the issue. Make sure the injector is in the correct direction. There is an arrow pointing in the direction of water flow. It should be away from the machine. Use only 1 50 foot of water and pressure hose.
Hello, Do you have any experience or knowledge of Ryobi 2.5 GPM pressure washers with a downstream injector? I have a Ryobi 3100 PSI 2.5 GPM. I bought an injector from amazon with a 2.0mm orifice that said that it works with 2-5 GPM machines, but it did not work. I am going to try your troubleshooting steps starting without the pressure hose and see; I read on the reviews some people complained that it did not work with a 50ft pressure hose and others that it worked. I also ordered a 1.8mm orifice injector to try because I think the 2.0mm is more for 3-5 GPM.
@@Brian_the_repair_guy OK, I did the test step by step as you explained. First with the 2.0mm injector, it worked but when I attached the 1/4” hose 25ft stopped ✋ sucking the soap then I tried the 1.8mm injector and that one worked with everything attached. I did a “draw” test and I got 0.25 gal soap per every 3.5 gal water that is equal to 1:14. Using a 10% SH equal to 10÷14= 0.7%. I guess 0.7% is the most I can get? What I will need if I need a 1.5% SH Strength coming out of the pressure washer gun? Or 0.7% is the most I will get with my Ryobi 3100 PSI 2.5GPM?
@@Brian_the_repair_guy That's awfully kind of you! I have suction with no hose and with hose but as soon as I connect my adjustable wand, no suck. I bought a new gun tonight but its too late to try it. One thing I did notice though that has me puzzled...when i attach the injector to the line it causes a huge load on my engine when the trigger is released and would kill it if I didn't pull the trigger. All works fine without the injector attached. I am using 3/8" quick connects on both sides of this adjustable injector
@@dtman66 I have never seen the load change with an injector. Very weird. Let me consider that one. If you get chemical with the pressure hose, but not with the gun attached, then a new gun is needed. Preferably one with a larger inside diameter. You are on the right track.
@@Brian_the_repair_guy I bought a new gun last night, 4000psi and 8 gallons per minute. My washer is 2400 at 2.4 so I should have plenty of flow. Still not working. It will however come out of the high pressure hose if it's not connected. By the way, I had a small leak in my quick connect that was causing the engine surge. Any ideas on why no suck? I'm about to return the injector to home depot and spray my house with a hand pump
Just got off the phone with Simpson, the seller of the injector. They said the injector is probably bad, which I believe, but also think it must be a bad design
Another great video. I have a question.. i have a 3200psi 4gpm pressure washer. My downstream injecter works until i put gun on so i know its the gun i bought. Saying its max gpm is 7gpm. What gun do i need? Help anyone
@@Brian_the_repair_guyhe wand itself is 1 piece then of course quick connects to gun. Also I'm filling a 5 gallon bucket with water hose in just under 30 sec. Could it be to high of inlet pressure?
@@dbac8891 if you are using the black tip, 50ft of pressure hose and the injector is not working with the gun then I would definitely change the gun. If the inside diameter of the gun and wand are too small the water is restricted and the injector will not work. MITM from Sherwin has a good one piece wand that usually works for most all washers and flow rates
Hi mate. My pressure washer today started spewing water out of the injector after not using it for a few weeks… I’m confused as to why this is happening and not the most savvy person - any advice to fix it? I only turned the water on not the machine and then left it off
There is a ball, spring and oring inside the injector fitting. The ball may be stuck. The spring may be rusted out. Or the injector could be bad. I would take the chemical hose off. Set the machine on concrete and remove the injector fitting to look at the condition of the ball oring and spring. Pay close attention to the order they come out so you can put it back in that order.
Good vid. Your f/u to the plethora of questions is impressive, commendable that you take the time and give your valuable time to help so many. Quality.
Good video. I have a question for you and hopefully you can help me out with my pressure washer issue. It won't turn on but when I put a little bit of Carb/Choke cleaner, it works but only for a few seconds (Husqvarna 3100). Thanks a lot in advance sir!
I'm having a problem with my xr2500 Honda pressure washer. My chemical line pumps water into the chemical bucket constantly if I don't pull the trigger. It's constantly blowing itself off of the chemical hose connector, too. Is that something I can fix? They don't make any parts for my pressure washer anymore. ☹️
@@Brian_the_repair_guy Dumb question, which part is that? I've already replaced the chemical hose with the filter on the end. I just placed an order for the small, brass piece with the spring and ball bearing in it but it's not here, yet. Sorry to be such an idiot. 🤷♀️
@@karenb6791notakaren not an idiot at all. Only a fool assumes to know it all. The chemical injector is the piece that you have order. The brass piece that the hose hooks to. This should fix the problem
Hi Good explanation. My issue is the motor seems to get water in it when left outside. I think it comes in from the air filter, what's the best way to get the water out? And also after sitting, the pull start will seize, how can I prevent this, so I don't have to remove and force it each time? Cheers
More than likely the engine will seize due to rust (light rust) forming in the cylinder. Best think to keep either issue from happening, store it in a dry location
Guns and Hoses😆. I unscrewed the big black chemical regulator dial so much that it came off. Problem is.. I can’t screw it back on with the spring inside. The threads won’t catch unless I remove the spring. Help!
It does not have a vent. I’m going to take the part apart that has the little spring in it to see if the ball or spring is stuck or damaged. Something is not closing that prevents water back flowing into the soap tank.
So im not supposed to have the original downstream injector from the pressure washer and the other downstream injector I bought both on the washer only use 1?
I am not sure of your specific set up. Typically you only have one injector set up at the time. Unless you can turn the intake off on one of the injectors, the injector that is not being used can leak or draw air into the system.
Hello i am trying to use a downstreamer on a 2.4 gpm craftsmen everything is working fine besides it is not sucking the chemica properly. Ive tried everything we mad sure the ball was no stuck everything seems to be in the right place but it is still not working. Help!!
My guess would be you do not have enough water volume. Not pressure, but water volume. The injector works on low pressure but an increase of water volume. Your pump only uses 2.4 gpm, but your injector may require more gpm than the pump. You need to determine what gpm the injector needs and calculate how many gpm you are getting to the machine.
@@Brian_the_repair_guy thanks. Wasn’t sure with the ball seating one way or the other. I’ve bought 2 injectors and can’t seem to get either to pull chemical or soap. I have a 4gpm machine practically brand new. I can hear the ball shake in them both. I can drop the injector into water and blow through the tube and see air bubbles. I’ve water tested my water source filling up a 5 gallon buck less than a minute. I’m gonna see if I get chemical with no pressure hose on. It’s a new line 100ft , and gun . 🤷♂️
@@NoName-be5ir the ball does not move like that. The ball is held in place with a spring, so it will not rattle. Make sure the flow of water is correct through the injector. There is an arrow on the body of the injector that shows the direction of flow.
@@Brian_the_repair_guy by your process of elimination I got it pulling till the high pressure line is attached. Then it stops pulling. I replaced the original 50ft with a 100 ft yamatic high pressure hose. I’m now seeing the size difference between the two. The original being much bigger. So the problem seems to be the smaller high pressure hose? Thanks for your replies, I e been banging my head against the wall over this supposedly just plug and play part. Lol🫤
Hello I have a problem. I brought a new 150' hose and my chemical injector stopped working. It will work with my shorter hose but not with the 150' hose. Can you help me??
With the added length of hose, your washer pump may not produce enough volume to allow an injector to work properly. If you need the added length, you can try a wand injector. It attaches to the tip fitting on the gun. Most use it for acid wash. It will work will most all chemicals.
@Brian_the_repair_guy I have a new 4200psi 4gpm gx390 with a fixed injector. I untighten the injector I seen a bent spring and a ball that look like a bb. But no o ring
@@papintoodeep depends on the injector. Most injectors the o ring goes in the nipple, then the ball and the spring (direction of the spring depends on the type of spring)
I have no idea if you can use both. If I had to guess, I would say it depends on the volume of incoming water to the machine. If your water volume is already borderline low, then I find it hard to see both injectors functioning. I think I will set up a test tomorrow and see.
Thanks for taking the time to explain how chemical injectors work and how to isolate the issue to repair the problem. Best explanation I have been looking for.

Brian, thank you for putting this video together! This really helped me in troubleshooting my issue and it seems a quick buy of 100 foot quarter inch hose is causing some back pressure. I swapped to the original 20 foot it started siphoning chemical. It is stated online that with a 2700 psi pressure washer if I go over 60 foot it will most likely stop the chemical to siphon though. I will go with a 50 foot 3/8 hose and try again.
Glad it helped!
I had the same exact problem. I have a 3.2GPM with 100’ of 3/8 hose, no draw. Switch to the stock hose and got my draw back. Kinda annoying to switch hose between soak and rinse, but I figured it out.

The geyser is caused by the ball missing, possibly other items missing as well. A full rebuild kit would correct this.
@@Brian_the_repair_guy Thanks Brian. I assumed as much. There are 2 kits. #8 includes the items mentioned in the previous post. Kit #9 includes parts downstream of Chemical barb adapter to the pressure hose connection. Do you think I may need these? Or could it have been a water volume issue all along and I messed up when I took the Barb adapter off.

So do you block the built on injector chemical hose off & use the new chemical hose correct? I have a issue where water is coming through my chemical hose & it take a minute to come out. I have the same exact injector for my 2.4gpm simpson, brand new. Took it apart, lubed everything from wand to pump to tank. chemicals wont feed with black tip in gun.
If you are going to use another injector, then yes you should block off the factory injector.
So why is water going building through my chemical hose? Would the check valves have anything to do with it? Water pressure is fine it's just the saop dispenser
@@tyrellgatling5666 when the injector goes bad, it will push back into the chemical.
This is exactly what I needed to learn and get help with. Thank you
@@BrianGemberling glad to help
Thanks for the thorough explanation and trouble shooting procedure. Exceptional job!
I hope it helps
I took off the injector and it was packed solid probably with calcium or hardened soap and will need to be replaced. Is it likely that the “mixer” (or whatever is in the adjoining part) also has this impacted material? I appreciate the way you explained things in the video, so I figured you understand the workings of the mixer as well.
Thank you.

@@JonFish-lg3yw any part from the injector out to the gun has the possibility to have this build up. Anything behind the injector should not have build up, unless the water itself is heavy in minerals
I just had this problem. Had to break out the pump sprayer. First thing I noticed was the customers water flow was weak. I'm gonna test it now with my supply, but I knew that was the problem. You confirmed it.
Glad to help.
I’m hoping you can help me. I bought a 4200 PSI 4.0 DeWalt belt driven with a Honda engine and a Cat pump about 2 years ago and never used it. I pulled it out today for the first time and it’s not picking up chemicals. I’m getting over 5 gallons per minute ( overflowed a 5 gallon bucket in 43 seconds ). I took it apart and the ball and spring are not stuck and freely moving. The arrow is pointing out. Everything looks great it just isn’t picking up the chemicals. Do you have any other ideas I can try?
Make sure you are using the correct tip. Disconnect the pressure hose from the machine and run it with water and see if the chemical injector pulls with NO pressure hose.
So do you have both chemical injectors attached? Or do you plug one suction and use the quick connection one? Idk I need to know if you are using 1 or both on the machine
@@duderock123456 if you have one that is built on like the one in the video, you have to plug it to use the other injector.
Thanks, getting no chemical out using what seems to be the same adjustable external injector, but my machine is built with a built in injector that would inject IN the pump, which I do not want to use. So trying to use this external injector leaving the built-in one unused, would this explain why I do not have any chemical going out ? Should I block the entry of the built-in one for the external unit to work !? Any advise would be appreciated, Thanks !
It may or may not affect the output. If you can catch me in Facebook with some picture of the set up, it would help
Thank you so much! By watching this video, I realized what you said and showed makes perfect sense. Now, I need to take mine apart and start over bc I did everything backwards 🤣🤣🤣
I am glad it helped
Very well done. If the check ball and spring are gunked up is there an effective way to clean them as well as inside of injector ?
Just washing is off with fresh water, be careful with the spring, it is a very light gauge
Thanks! Will do.

I have a question, and thank you for the video, I have the same set up as you in this video on my 3.2 GPM and I want to use my down stream injector (same as yours) rather than the stock injector (same location as yours). Can I cap off the stock injector to use only my down stream injector??? Reason I’m doing this is I’m running hot SH mixes sometimes and I do not want any back flow going into pump at all as that will destroy the pump. I will also be upgrading machine in future (8 GPM belt) and would rather keep the same set up. Thank you if you or anybody else can respond.
Yes. Cap off the barb by the pump.
Great explanation. I have that same injector and it is brand new as is the 5 gpm 3000 psi machine. I used it one day and started having trouble with the ball getting stuck in it's o ring seat. I am very mechanically inclined and have taken it apart several times now. What is weird is that when I throttle down the machine and the flow and pressure drop it sucks like you know what!. If I throttle it wide open the ball gets jammed in the O ring from back pressure I guess and stops sucking. I am only running 100' of brand new hose. everything is sized correctly and is brand new. The ball itself to me feels like it is not perfectly round from the factory. Now I did over tighten the adjustment collar thinking it was loose the first day i used it. not realizing it was an adjustable metering thing, I thought oh crap I need to tighten this up so I did with small channel locks but I don't think it was enough to damage the O ring. But I think it likes to get stuck really easy when the pressure goes up now. Have you seen this problem or just replaced the O ring seat before? Any thoughts would be appreciated Thank You!!
I have never seen that myself. A rebuild kit is inexpensive and may fix the issue.
Wow! That was very helpful at the right time. Thank you for taking the time to make this video.

Brian, what would cause the water to flow backwards, thru the downstream injector, into the 5 gal bucket where the SH is? This happens to me now n then.
The spring, ball or Oring could be failing. A rebuild kit or replacment of the injector
_Hey what do you think would cause my injector to suck water back into my 5gal bucket vs. pulling the chemical out like it should? It's not installed backwards either & I've cleaned the ball & spring yesterday with wd40 I'm frustrated now.._
The injector needs to be replaced. There is either damage to the ball, spring or oring. If you contact watercannon.com they may have a rebuild kit
Hi Brian, Thanks for the helpful video. I connected an injector to my Simpson 2.5 GPM machine. A strange thing happened. The pressure of the water through the injector without the machine running caused a narrow jet like spray with no chemicals. When I stopped the flow with my thumb and released it the water came out like it would if it were from a detached garden hose.. but it was full of chemicals which tells me the injector is working.
When I attached the pressure hose with the black/soap tip and the engine running no chemicals were produced.
I’m lost as to what the problem is.
If chemicals are moving with no pressure hose and gun, but do not move with the pressure hose a d gun then typically the hose or gun is the problem. If they have build up or corrosion they restrict the flow and the injector will not work properly
🙋Can this work on a DeWalt with the built-in injector?
Many thanks brilliant insight into the possible problems, I recently had a issue with water coming out of the chemical hose feeding back into the acid.
Any ideas regarding this problem
Bad spring, ball or Oring. Rebuild the injector or replace it
Many thanks, what is the location of the O ring
@@jonbon-bz2cb it is located in the barb that the hose attaches to
Thank you for the Video. Where should I look when water is back feeding into my dispenser? I get soap when I have the trigger pressed but when I let off water goes into my soap dispenser.
Your chemical injector needs rebuilding or replacement
@@Brian_the_repair_guy Thank you
Which inductor is better? The fixed one or the one that you can remove/turn off? I’ve had the fixed one on for a while and it seems like it always introduces air as opposed to being able to turn the valve off on the inductor to stop that…. What do you think about that?
I like the removable unit. They are usually rebuildable and if they stop working, they have a leak you can take them off so they don't pose a problem with the pressure
thank you so much for taking the time. best explanation I have seen.

Really appreciate this video. Did the elimination steps, turns out it was the green flexible aftermarket hose. Put the OEM hose back on and it now siphons correct ly.
Good stuff. Glad it helped
Great video Brian! can you leave the factory injector in place as is and quick connect your adjustable injector and use that to siphon the bleach while still leaving the factory injector in line unused with no siphon hose attached? Would the adjustable one still work properly with the factory 1 left open or Would you need to plug the siphon barb from adding air into the line?
Plug it.
How do you plug it?
@Lupe Dominguez I am going to just tape over the factory installed injection barb. I think that will cut down on the draw of s h ..
Very helpful Brian. Thank you. I took my injection valve apart and unstuck the ball put it back together again but still my Simpson MSV3024 refuses to pull chemical :(
There are other reasons way it may not be working. Be sure to check everything listed in the video. If none of this fixes the problem rebuild or replace it

Hey Brian thankyou for helping me troubleshoot the issue. It's discouraging considering I just bought the Simpson Clean Machine 3400 PSI 2.5 GPM 4 months ago and have only used it twice. It seems to be the actual pump that's the issue, I have the spring, the ball, the water volume is good. When I took off the pressure hose and just had the water turned on it was not sucking any chemical. I only used it once before and it worked great. I am not sure what the issue is. Any thoughts would be greatly appreciated.
Your pump should not be an issue unless it has an obstruction. If you have 5gpm going to the pump and it is not producing chemical without the pressure hose on, then you would have an injector issue.
Thank you. Great tips for me to try getting my soap flowing. New machine, 2nd use and the detergent stopped flowing. Cheers
I hope it helps
Fantastic video!
Excellent explanation!!
I’ve been searching TH-cam for basically 2 days and watched at least 25 or 30 videos trying to understand why my chemical injector works without the hose/wand attached, but stops drawing when attached.
Side note: after disassembling the injector numerous times (at least 5 😂) I lost the spring! Time to cap it and get an external one.

I know it’s been a year but I’m really looking for your help. So I have a 4gpm with 4200 psi. And I use the fixed downstream injector. My chemical is being sucked up when I have the hose it came with which is 50ft. And I use it with a new gun I bought and works fine but when I put a different hose which is 100ft or even my 150ft hose the chemical does not get sucked out but hears the funny part I know in your vid you said it’s the hose but I think in my case it’s not because when I don’t have the gun the hose and the hose is just releasing the water through the ball valve the chemical then isss being sucked out but only when the ball valve is fully open. When I put the soap tip with the gun it ends up not working anymore. What is my problem?
When you have 100ft or more with the gun, the injector has a much harder time working properly.
Great detailed video! This is the problem I’ve run into. I have a Simpson 4000psi / 3.5gpm. Chemical injector stopped pulling chemical, so I put in a new one.
Ive tried a bunch of things. When the water is on, but the machine is OFF, it will pull chemical. I tried it with and without the hose, gun, tip, etc. strong suction.
When the machine is ON, the suction is very weak and will not pull chemical, regardless of hose, gun, tip, etc.
Have you tried turning the pressure down?
@@Brian_the_repair_guy yes, it seemed like suction would increase for a split second, then back to no suction
Hey, on these pumps, are they bsp or npt tread fitting?
Thanks!!
Typically they have NPT on most fittings, there are a few that are not.
@@Brian_the_repair_guy thanks mate, I’m fitting a easy start valve and trying to get all the correct fittings. My pump is the same as yours
@@jamesbloomfield2741 glad to help
I have that same exact washer. How high pressure can you go before that Soap stops injecting? 75 . Thanks
The volume of water, not pressure will dictate the flow of soap in the injector. You must use the black tip to allow the flow of soap. If there is no flow, then follow the direction in this video
Hi Brian, I have a NorthStar pressure washer 9hp 3GPM with a CAT 4SPX pump. The downstream chemical injector works with the wand and black tip but won't work when I attach the 18FT washer pole I also purchased (tip or no tip). I have had both of these for 10 years but never tried to spray chemical though the pole until today. I thought I may have too much hose so I connected the 18FT pole strait to the unit (no hose) and still won't siphon chemical. Any ideas?
This is typical. The addition of the pole changes the requirements for the injector to work properly. You can look for an injector that attaches at the end of the wand. I have seen guys put their injector at the connection between the gun and hose with success
Very well explained! Thank you
I hope it helps you
Brian Shumack. Your explanation on how to trouble shoot a down loader is great! REALLY ! Yet, I am still having difficulties. I replaced my rusty cannon ball valve with a new one. I started my machine without the pressure washing hose attached and it drew chemical right away. Then, i attached just the pressure washing hose and again, it drew right away. Then, i attached the gun (without the tip) and again, it drew right away.
Then, i installed the tip and everything stopped! No draw, no nothing. Could this be my gun is failing ?
Yes, i started with the black chemical tip and i even tried the pink tip yet, nothing.
It is possible one of a few things is occurring. If each thing is working up until the tip, I would suggest switching the hose or gun and see if there is a change. If you have a build up of corrosion in the hose or gun, the tip could allow just enough of the flow to be reduced so the injector fails. That would be the easiest thing to try first.
Make sure the water is full pressure from the faucet and use no more than 50 feet of water hose. Let me know what you get. If this does not resolve the issue we will look at other possibilities.

What about if u have a new spring and ball, even tring a added injector but can't get any suction but can blow thru the injector, and water pressure is very good . Having troubles with 2 Dewalts, a 3800 and 3400psi series
1. You must be able to fill a 5 gallon bucket in a minute to insure you have enough water volume.
2. If the volume is good, hook 1 water hose to the pump, install injector, turn water on, turn engine on, see if you get chemical. If you do, then your pressure hose or gun is the issue. If you do not get chemical then the injector is the issue. Make sure the injector is in the correct direction. There is an arrow pointing in the direction of water flow. It should be away from the machine.
Use only 1 50 foot of water and pressure hose.
Simple clear precise instruction thank you
Thank you hope it was helpful.
Hello, Do you have any experience or knowledge of Ryobi 2.5 GPM pressure washers with a downstream injector? I have a Ryobi 3100 PSI 2.5 GPM. I bought an injector from amazon with a 2.0mm orifice that said that it works with 2-5 GPM machines, but it did not work. I am going to try your troubleshooting steps starting without the pressure hose and see; I read on the reviews some people complained that it did not work with a 50ft pressure hose and others that it worked. I also ordered a 1.8mm orifice injector to try because I think the 2.0mm is more for 3-5 GPM.
First step as you said, run it without the pressure hose. See what you have. Then move on from there with your results. Let me know what happens
@@Brian_the_repair_guy OK, I did the test step by step as you explained. First with the 2.0mm injector, it worked but when I attached the 1/4” hose 25ft stopped ✋ sucking the soap then I tried the 1.8mm injector and that one worked with everything attached. I did a “draw” test and I got 0.25 gal soap per every 3.5 gal water that is equal to 1:14. Using a 10% SH equal to 10÷14= 0.7%. I guess 0.7% is the most I can get? What I will need if I need a 1.5% SH Strength coming out of the pressure washer gun? Or 0.7% is the most I will get with my Ryobi 3100 PSI 2.5GPM?
@@JavierRivera to get more, you need a pump that will give more gpm as well as a delivery from the faucet that is equal to or higher than the pump
@@Brian_the_repair_guy THANK YOU. Do you mean another pressure washer that is 4GPM instead of 2.5GPM? My water source is 7GPM.
@@JavierRivera yes

@@Brian_the_repair_guy That's awfully kind of you! I have suction with no hose and with hose but as soon as I connect my adjustable wand, no suck. I bought a new gun tonight but its too late to try it. One thing I did notice though that has me puzzled...when i attach the injector to the line it causes a huge load on my engine when the trigger is released and would kill it if I didn't pull the trigger. All works fine without the injector attached. I am using 3/8" quick connects on both sides of this adjustable injector
@@dtman66 I have never seen the load change with an injector. Very weird. Let me consider that one.
If you get chemical with the pressure hose, but not with the gun attached, then a new gun is needed. Preferably one with a larger inside diameter. You are on the right track.
@@Brian_the_repair_guy I bought a new gun last night, 4000psi and 8 gallons per minute. My washer is 2400 at 2.4 so I should have plenty of flow. Still not working. It will however come out of the high pressure hose if it's not connected. By the way, I had a small leak in my quick connect that was causing the engine surge. Any ideas on why no suck? I'm about to return the injector to home depot and spray my house with a hand pump
Just got off the phone with Simpson, the seller of the injector. They said the injector is probably bad, which I believe, but also think it must be a bad design
Can you use the downstream injector on a machine that skat already has a factory injector
Yes, typically you want to render the built on injector unusable. So the injector intake needs to be plugged.
Another great video. I have a question.. i have a 3200psi 4gpm pressure washer. My downstream injecter works until i put gun on so i know its the gun i bought. Saying its max gpm is 7gpm. What gun do i need? Help anyone
Is your gun a 2 piece set up? Meaning, does the wand screw together?
@@Brian_the_repair_guyhe wand itself is 1 piece then of course quick connects to gun. Also I'm filling a 5 gallon bucket with water hose in just under 30 sec. Could it be to high of inlet pressure?
@@dbac8891 if you are using the black tip, 50ft of pressure hose and the injector is not working with the gun then I would definitely change the gun. If the inside diameter of the gun and wand are too small the water is restricted and the injector will not work. MITM from Sherwin has a good one piece wand that usually works for most all washers and flow rates
Ok thanks I will try that
Yep it was the gun. Thanks for taking the time to help buddy
I have a 5 gallon a minute pressure washer, so if I ain’t giving it 5 gpm it won’t work.?
If you machine requires 5gpm and you are giving it anything less than 5gpm, then it will not work properly. Can cause damage or destroy the pump
Best explaination I've seen. Thanks.

Hi mate. My pressure washer today started spewing water out of the injector after not using it for a few weeks… I’m confused as to why this is happening and not the most savvy person - any advice to fix it? I only turned the water on not the machine and then left it off
There is a ball, spring and oring inside the injector fitting. The ball may be stuck. The spring may be rusted out. Or the injector could be bad. I would take the chemical hose off. Set the machine on concrete and remove the injector fitting to look at the condition of the ball oring and spring. Pay close attention to the order they come out so you can put it back in that order.

More than likely the engine will seize due to rust (light rust) forming in the cylinder. Best think to keep either issue from happening, store it in a dry location

Well, no easy way to say but to keep trying. It is frustrating at times
It does not have a vent. I’m going to take the part apart that has the little spring in it to see if the ball or spring is stuck or damaged. Something is not closing that prevents water back flowing into the soap tank.

So im not supposed to have the original downstream injector from the pressure washer and the other downstream injector I bought both on the washer only use 1?
I am not sure of your specific set up. Typically you only have one injector set up at the time. Unless you can turn the intake off on one of the injectors, the injector that is not being used can leak or draw air into the system.
great advice 👍🏿👌
Hello i am trying to use a downstreamer on a 2.4 gpm craftsmen everything is working fine besides it is not sucking the chemica properly. Ive tried everything we mad sure the ball was no stuck everything seems to be in the right place but it is still not working. Help!!
My guess would be you do not have enough water volume. Not pressure, but water volume. The injector works on low pressure but an increase of water volume. Your pump only uses 2.4 gpm, but your injector may require more gpm than the pump. You need to determine what gpm the injector needs and calculate how many gpm you are getting to the machine.
Should the injector always be in the up position, the clear tube on top?
The direction makes no difference. The injector will work in any position
@@Brian_the_repair_guy thanks. Wasn’t sure with the ball seating one way or the other. I’ve bought 2 injectors and can’t seem to get either to pull chemical or soap.
I have a 4gpm machine practically brand new.
I can hear the ball shake in them both. I can drop the injector into water and blow through the tube and see air bubbles. I’ve water tested my water source filling up a 5 gallon buck less than a minute. I’m gonna see if I get chemical with no pressure hose on. It’s a new line 100ft , and gun . 🤷♂️
@@NoName-be5ir the ball does not move like that. The ball is held in place with a spring, so it will not rattle.
Make sure the flow of water is correct through the injector. There is an arrow on the body of the injector that shows the direction of flow.

Hello I have a problem. I brought a new 150' hose and my chemical injector stopped working. It will work with my shorter hose but not with the 150' hose. Can you help me??
With the added length of hose, your washer pump may not produce enough volume to allow an injector to work properly. If you need the added length, you can try a wand injector. It attaches to the tip fitting on the gun. Most use it for acid wash. It will work will most all chemicals.

Should o ring sit inside ,ball in middle then spring ?
@@papintoodeep depends on the injector. Most injectors the o ring goes in the nipple, then the ball and the spring (direction of the spring depends on the type of spring)

i was just gifted a pressure washer and after the first initial burst it will shoot water out that valve any ideas
If water is coming out of a new injector, then the ball is typically stuck
Could you use both injectors? 🤔 One to pull SH and the other to pull surfactants?
I have no idea if you can use both. If I had to guess, I would say it depends on the volume of incoming water to the machine. If your water volume is already borderline low, then I find it hard to see both injectors functioning.
I think I will set up a test tomorrow and see.
