Running a Pressure Washer with a 12v pump and a Buffer tank

- I’ve uploaded a couple videos before this one of trying to run my direct drive pressure washer with a buffer tank. I’ve tried to gravity feed it with an ibc tote and did not satisfy me. Now in this video I tried using a 12v pump to feed the water in my buffer tank to the pressure washer.
The pressure washer I use in this video is a BE 4200 pressure washer with a Honda gx390 and a 67dx Cat pump.
Preview to a Future Video....
I just got a belt driven pressure washer with a bypass!
BTW, exactly how you should setup your buffer tank, pump, and strainer. Add a float valve to the top of the tank with a garden hose fitting so the tank will auto-fill from the customers water as you use it up.
I am finally making a new video today to go over my setup as much as possible
Hey there’s a small allied screw that needs adjusted until the Everflow runs smooth adjust with you washer on and ballvalve open completely
Take an Allen wrench stick it in the top of the 5 gallon a minute pump pull the pressure washer trigger turn the Allen wrench till it stops posing
I have the exact same machine never had a single issue with it since i bought it new in 2019, it’s pulsing because one of the check valves on the high pressure side of the pump has some trash in it
did you also put a pump or do you run it straigth to your tank with no issues?
@@alexisbarrera7789 he said he never used it dude!
Did you get it figured out dude? There's an allen screw that can be adjusted to fix the stutter on the pump.
Did not know about the Allen key. Lol
The only work around using a buffer tank is for the tank to be slightly higher than the inlet on the pressure washer if you dont have the minimum GPM that the pressure washer is rated for it will cavitate and pulsate because the pressure washer is not getting enough water flow. The electric pump needs to be at least 60-70 psi and about 20% more GPM than the pressure washer is rated for.
Do you think this set up can work for just priming the pump and then just using the buffer tank to run a 8gpm pump?
@cozmozreveng I run an RV water pump to pull from my buffer tanks and it works fine. But I also had my newer designed CAT pump replaces with the older more tried and tested CAT pump. Open your ball valve or squeeze the wand trigger while doing this turn in the electric pump until you have flow out of the valve or wand then start the pressure washer engine. When shutting down just do these steps in reverse. The choice in water pump is important also as some will shut off for thermals and you will have to wait a while before they will re energize.
I think you just need a larger diameter feed to pump inlet from buffer tank... maybe 1 1/2" and then no need for the 12v pump. I don't think that little garden hose can supply enough water for a 4gpm machine. I'm not yet on a buffer tank but trying to design my system by checking out other's.
Yea ur right a garden hose isn’t enough to supply water. I ended up ditching this and getting a belt drive 4gpm pressure washer and gravity feeding with a 1 inch hose.
The 12v pump is a better way to go for a direct drive, it just doesnt produce enough suction to reliably feed itself. You can get away with the gravity and no pump when a larger buffer tank is full but you are rolling the dice on burning it up. And pretty sure its a 2mm allen to adjust that 12V, turn it untill it runs smooth then give it about a 1/4 turn more and should be good.
5/8 hose is plenty to supply 4gpm
Your in the right path when it comes to needing a bigger hose you only need a 1 inch hose from buffer tank to pump inlet but the hose had to be the perfect length from tank to pump, and the tank out let hose will need to be higher then your pump inlet , if there is any part of that hose that sits below your inlet, it wont work and you will need to add at least 8 gal a min pump closest to the tank at least 40 psi, as a rule of thumb always double your pump size , 5 gallons isn’t enough power to force water in to your pressure washer pump
Small Allen wrench to adjust the small setting screw on the 12 bolt pump to get rid of the pulsing
Didn’t know about the Allen key... ended up going with a belt drive and got rid of the 12v pump
@@extremegreen5092 Save the 12volt for soft washing
Hey man how has it held up so far?? I got one for my PW as well and it pulses just like yours
How long at a time do you use it and have you had any issues with it.
Did you figure out how to get it to stop pulsing?
Those 12v pumps have an Allen head screw at the top to adjust it. Leave ur PW off but flow water thru it with the trigger pulled on your gun and adjust the screw on the 12v pump until it stops pulsing
Harbor freight has a pump for super cheap that will remedy this also. $50 and you're good to go
Hello brother if running water supply to pressure washer no need of 12 volt water pump
U just need to put the pressure washer lower,
The tank must be higher than the pressure washer dude I had same issue the water intake valve on your preasure washer must be lower than the outlet on your tank 😅
Why does your pressure washer need a pump ? Do you still use a 12 V pump to feed your Pressure washer ?
YES, pressure washers need a minimum input flow and pressure to work.
@specialservicesequipment393 How would you determine the minimum input per GPM output?
My pump will be in tomorrow I'll see what mine does once I get it plumbed up
I learned from a couple buddies and my local pressure washing store that if you want to use a buffer tank the one thing you need is a bypass to the tank. Does your pump have a bypass? And what model pump is it by chance?
@@extremegreen5092 it is a AR viper u talking about the hose that comes from to the unloader that goes down
@@dirtblasterspowerwashing yes. Well to add more. The hose that when you let off the trigger it lets water out of the pump so it doesn’t overheat
@@extremegreen5092 yeah that makes since
@@dirtblasterspowerwashing so you gonna replace your current pump to run it with a buffer tank?
I had to do the same. Works fine.
Your chemical injector is sucking air, that’s why it’s pulsating with ball valve
Why are you using a 12v pump to draw water from your buffer to your PW. Especially from a IBC tote. I've never needed a booster pump ever as gravity is your friend, Good luck man. :)
@sundown798 I also run mine with no pump but my 5.5 gpm machine is belt driven not direct driven
The problem is that some pumps don't pull water, they have to be feed with a consistent gpm flow and pressure. Mine is a blue cat pump and it will "not" work at all.
I have not set mine system up, yet you don't there is a need for a 12v pump?
hmmmmm......but why not just get a pump that produces it's own suction in the first place? Feeding a pump with a pump seems like it's just asking for unnecessary problems.
Well said sir!
where did you get that filter?
Amazon it was like $12
How many gpm is your 12v pump?
5.5 gpm
