Water Pump Question

[CrxSiR-GNY]

I was wondering what some of your setups are in regards to getting water from a water tank to a gas pressure washer.

I purchased a tank and mounted it in the bed of my pickup. I have a gas pressure washer and am wondering what pump is going to be ideal to supply the water to the pressure washer. Would a 60 or 70 psi 12v water pump be fine to supply a standard 2600 psi pressure washer that can be found at home depot?

any suggestions and information you have to offer are greatly appreciated. Thanks

you need to know gpm not psi. For both your pressure washer and pump.

You could just gravity feed. The way I have my setup is I have a short hose custom cut with a male and female connection from Lowes (If you don't have a Lowes in your area, then Home Depot, etc.), and then connect it from the tank that is on my trailer to the pressure washer that is on the ground, that way I will get a good flow of water from the tank. This may not work too well if you have both your tank and pressure washer in the truck, and therefore you would then need a pump.

the pressure washer gpm is 2.3

So all I would need to do is be sure that the pump can produce at least 2.3 gpm?

here is the one i have been looking into:

Grainger Industrial Supply: Potable Water Supply Pump,12 VDC,174 GPH 2XE90

would I be able to use something like this?

I have a 60 gallon tank mounted in the bed of my pickup. Since the pressure washer is going to be on the ground while in use you dont think I would need a pump?

Does any one else have any other suggestions?

You shouldn't need one. As long as you connect a small hose from the tank to the PW, the water flow should be adequate enough. Also, I recommend that you get a full port ball valve for your tank (it has a better water flow and is easier to use).

Read “small hose” as short, not skinny. You want a short distance and a big diameter to maximize flow. That’s why you want the full-port valve.

If you aren’t sure if your setup will flow enough, get a stopwatch and a bucket and time how fast it can fill the bucket. It should put more gallons per minute into the bucket than your pressure washer can use at maximum output. If it can’t do that then it’s too small.

I have never seen any one need an external pump to get the water to the pressure washer. The pressure washer has a pump on it, otherwise it is called a gasoline engine, not a pressure washer.
