Greetings gang; i'm setting up a mobile rig and i have a little kink. Is there a workaround the 5psi input water pressure setting of the pressure washer? I connected a 250 gallon water tank directly to the pressure washer and no water came from it. The pressure washer I'm using is the Devilbliss Excell VR2522. Any of you guys have any suggestions
 
Though pressure washers do a great job of pushing water, most will not create sufficient vacuum to pull water. You've got to get it to the pump before it will push it. Some will do this with a minimal amount of feed pressure. Pressure from a garden hose is a no brainer but gravity may work. I've seen pumps that have been burned up while the user waited for it to pull water. Is your tank above your PW?
 
I didnt mean to come off as a smart ass. Ive known of this happening and it will cause the water to drain very slowly. If at least some water isnt getting from the tank to the power washer, thats the first thing I would check other than making sure the water is turned on.

Most hardware stores carry this and it is a must for an in-between from your tank to your pressure washer... or else you will burn your burn out your pressure washer's pump.
 
You could try turning down the power to see if any water comes out. What kind of pressure washer and how much psi does it have?
 
Thank u guys for the responses...Yes the tank is vented. I have the pressure washer on the ground and the tank is in my van...So a height of about 3 feet. I've never seen a pump like that but i surely could look for a unit like that. Was hoping to find a solution that didnt involve another consumer of power.
 
Any line going into a pressure washer needs to be pressurized in order for the washer to deliver properly. The pumps on a pressure washers require a continuous pressurized water source. If there is not adequate water to the pump, the unit will not operate correctly and the pump may sustain damage.

This happened to the $4500 steam washer at work when a new guy didnt turn the water on outside before trying to wash a truck. It ran long enough to run the tank dry, and after about 30 seconds of him still holding the trigger while trying to figure out what had happened, the pump went out. The worst part about it is there was a sign right in his face saying "before operation please make sure the water is hooked up and turned on". It cost my boss $1000 to replace it :rant:

I dont have one of those and I use my pressure washer nearly every day and have been doing so for over 3 years. Oh, and my water is stored in a 90 gallon tank...on the same plane as my pressure washer....i guess all that money i spent on my trailer was good for something....

Not all pressure washers are created equal, meaning that if your pressure washer is electric it may not need an in-between pump - If your pressure washer's pump is designed to pull as well as supply sufficient pressure that it may not need this unit.

Many pressure washers with Briggs & Stranton engines suggest that you use an in-between pump. My pressure washer which uses a Honda engine and has a variable pressure valve on the pump seemed to work fine without an in-between pump until I wanted to get my full 3800 psi out of the pump.

It is called research and development.:bigups
 
mine uses a briggs and stratton motor, and a pump built in house, I beleive. i dont have 3800 psi though, mine will only do about 2300, which is plenty enough for what i do, my pump even has a recirculation side.
 
I have a honda 2600 psi pressure washer and went to harbor freight and bought a fresh water pump ($50)..it hooks directly to a 12v battery. I use two 55 gallon barrels (meaning water pumps up from the top) and it pumps plenty of water to my pressure washer... I don't trust the gravity thing because my pressure washer requires a certain amount of water to be pushed through, so that it doesn't burn up the internal pump..also, when your water level gets low, you won't have much water pressure......"research and development"
 
Just prime your pressure washer with a garden hose then hook your tank hose to the pressurewasher while the water is running ( its a little messy) once primed you should be ok. Ive been using gravity from my tanks and have never had a problem with both electric and gas powered pressue washers
 
Slight thread jack as this seems to sit idle for a moment; anyone with that Wayne Porta Pump, could one of you manage to measure it's dimensions for me? I'm building this into a very compact mobile rig. Thanks for the help!

I used to run this pump until I started using the clients water. Its awesome, but at $150 it aint cheap!

This is the pump i use..and you dont need a batter if you just hook it up to a power source.. http://www.harborfreight.com/media/...ab33525d08d6e5fb8d27136e95/i/m/image_6044.jpg


Oh, and SCRUBS... If you're still thinkin about gravity, I've seen a guy around my town that drilled a hole in the bottom of his trailer and ran a hose from the bottom of his tank and mounted his water spicket on the side of his trailer.. so all he has to do is wheel his pressure washer out and hook it up. Says he has no problems.

Looks good but I have a generator on board so a power source isn't an issue.

Measurements anybody? :bigups
 
Sorry to thread jack, but can everyone who owns a pressure washer that has a pump from factory that is self priming (Pulls water to p.w) post make & model and or photos with any info you may like to disclose so that it may be a little easier on next member looking for a good unit without have to buy a sperate pump.
