You could improve this further by putting a shut off on your poly line, like the xjet has. Then, instead of pulling the hose from your bucket to rinse, you just close the shut off. A cheap solution.
I just got an old snow foam cannon, put in a bigger bsp taper thread for better chemical draw and put in a bigger orifice. Cost me £8 plus my old foam cannon, which was maybe £15. Connect a bigger hose to the sh and you've built an xjet.
Your suggestion is great. Of course its more cumbersome but so is an x jet. Sometimes when I am running 150' of hose I get hardly any chemical so I started doing exactly what your doing. Now I have to water the mix down.
This is an awesome idea I do store fronts in NYC Manhattan and I downstream only because that's what works, sometimes I just need a little stronger mixture
Hey sorry I realise this is 2yeara later but a downstream injector is not as good as an xjet. The downstream injector (at least the one that came with my setup) is a 5:1 set ratio, this cant be adjusted. There is a ball on a spring on the inside that pulls down against the spring as it draws via a vacuum (venturi) when you put water through. The spring and the ball are made of steel (normally) so they can in fact corrode over time. The xjet however has different inserts so you can adjust the ratio of water to chemical on the fly. It can range from 1:1 to 1:256. This allows for stronger mixes if you have stubborn black mould, or ligter mixes if it's just a light freshen up that is required. The xjet also has the fan blade that allows a better spray pattern than your standard nozzle and keeps the spray tighter to allow for better foaming upon spray, whereas the standard 40° tip will spray it in a wide pattern and not really foam it. Of course if you are just starting out as soft washing or even pressure washing. A standard 5:1 venturi is good enough. It means that if you have the standard 12.5% chemical mix then you will only be getting 2.5% at the gun, as opposed to the xjet being able to be anywhere from 6.25%, 4%, 3% to 0.5% if required.
And to top that.... Put a ds injector at the hose reel (or wherever you normally have it) and then do your method. This way you are downstreaming a downstreamed mix.
If i have a downstream device by the pump, can i still add this before the gun or do i have to remove the one near the pump even if im not drawing chemical from it?
Here see what you can do with this: .5 × .125 ÷.1 ÷ 4.5 ÷ .1 = .125 × 100 = 1.38%. So what is it?... Its the Mossberg-Campbell Sodium Hypochlorite dilution Equation for a power washer injector. Where: .5 is the sh draw in 1/10ths of a gallon. .125 is the sh converted from 12.5%. 1 is the time in minutes for the draw test. ...and 4.5 is the total sh and water through the system for 1 minute. Its a decimal fraction divided by a fraction. A number divided by itself is just that number! So on a 1 min test we can simplify and drop the fraction, but say the test is run for 30 seconds then the 1 becomes .5. You need a stopwatch and 1 gallon jug marked up in 10ths (which is 12.8 ounces). Then a container to catch the sh ( which is water for the test) and the water through the injector for 1 min). That is the 4.5 in the example.
Probably the a couple arguments I make for this sistem is longevity for your hoses, remember they are steel braided inside and SH is highly corrosive. And the other reason could be the drawing ratio frome the bucket, should be a higher concentration for sure. Other than that you'll have to manipulate 12% bleach on or off the truck (kinda dangerous) and for sure it sucks to carry a bucket around a property withallthe rest of the equipment... 😆🤪🤣 no way "F" I'll just buy ne hoses when the burst... that's part of the cost of running a business like this. 👍
Yes, and no, depending on the mold. I've done it for green moss and maintenance washes. But if you have dark black streaks, you'll need a bit more strength than this provides. I'm planning on experimenting with some forced or gravity fed injection for this purpose.

@@kyle-uu1ll I'd love to see this..

I run 200 feet no problem maybe your injector is bad
Same!
You just saved me a lot of time. Thank you 🙏🏼

I have a 4000psi 3.5 gallons this is nice it saves a lot of money my question is what tip you are using
M5DS softwash nozzle, but any softwash nozzle can work. That one is 65 bucks but totally worth it
Thank you

A 5 to 1 ratio with 12.5% chemical gives you 2.08% at the gun
You're not altogether wrong
I will say, I'm using an adjustable soft wash nozzle that does a fantastic job at foaming, fanning, or shooting up a few stories.
Once you switch to rinsing, how does that work????
Just pull the tube out of the solution!
And to top that.... Put a ds injector at the hose reel (or wherever you normally have it) and then do your method. This way you are downstreaming a downstreamed mix.
🤯
I've thought about this. Never tried it, all I've heard is that it won't work? Not sure why
Hey any clue what the actual draw from that thing is? for example, using 100% 12.5sh bleach.
It's rated for 20%, but with this setup I believe I get a bit more. Still have to dilute the sh quite a bit
Good info. Thanks. I will try that.
How do u know what amount of chemical is been used when downstreming
Go by results mostly. Spot test, adjust with dilution
If i have a downstream device by the pump, can i still add this before the gun or do i have to remove the one near the pump even if im not drawing chemical from it?
You know I have yet to try that. Some say no, but I'm uncertain to be honest.
I’ve tried doing this and the chemical won’t draw through.. do you need a specific amount of pressure before it actually draws
You need low pressure tips just like you would down streaming normally.
Should work with most machines, but your definitely need a softwash nozzle.
Hmm not a bad idea if you don’t mind moving the bucket and having two hoses. How long is the 1/4” hose?
Yeah, I detest the x-jet for that very reason... wrestling two damn hoses.
And if you knock the bucket over you're definitely killing grass
About 25'. That way I can sit the bucket down and do most of the side of a house. You can pinch the tube to rinse.
Here see what you can do with this:
.5 × .125 ÷.1 ÷ 4.5 ÷ .1 = .125 × 100 = 1.38%.
So what is it?...
Its the Mossberg-Campbell Sodium Hypochlorite dilution Equation for a power washer injector.
Where:
.5 is the sh draw in 1/10ths of a gallon.
.125 is the sh converted from 12.5%.
1 is the time in minutes for the draw test.
...and 4.5 is the total sh and water through the system for 1 minute.
Its a decimal fraction divided by a fraction.
A number divided by itself is just that number! So on a 1 min test we can simplify and drop the fraction, but say the test is run for 30 seconds then the 1 becomes .5.
You need a stopwatch and 1 gallon jug marked up in 10ths (which is 12.8 ounces). Then a container to catch the sh ( which is water for the test) and the water through the injector for 1 min).
That is the 4.5 in the example.
Do you mix your S H with water or streight out of bucket to do this.
It's mixed with water.

Good stuff man
Whats the ratio you get?
At least 20%. I haven't clocked it, but it's strong enough that the SH has to be cut in half or more
Have you done a drawn test?
No, in fact my business focuses on window cleaning strictly now so I might never know 🤷
Could I clean a roof that has mold on it with this method
Yes, and no, depending on the mold. I've done it for green moss and maintenance washes. But if you have dark black streaks, you'll need a bit more strength than this provides. I'm planning on experimenting with some forced or gravity fed injection for this purpose.
Buy a flow pro instead then you can remotely turn off soap and sh then rinse the injector this is better than pulling 1/4 line all over the place
Thanks for the tip
Where can i buy this injector? O have a 2.5gpm 3600 psi machine
Cwc supply, Amazon, just Google downstream chemical injectors
Google- be resourceful.
I always asked myself why can't it work this way,have you ever ran into any difficulty
Nope, other than the tube getting cumbersome, but the same thing happens with an x-jet
I always figured that would work. Thanks
Glad to help!
With a 4gpm machine what % mix do you think it would be? I am looking for a 3% SH mix for driveways.
You just have to check the specs on your valve. This one is 20 percent.
people typically put downstream injectors on the other end of that hose. Also, not softwashing but ok...
I'm sure you're a very knowledgeable person. I'll take any input you have!
