Water pressure affects on pressure washer

**MrGolfRider** · 06-01-2011, 10:07 AM

So I have a gas pressure washer that was given to me and I wanted to ask the community if there is a standard for water pressure into the unit.

Where I live has really low water pressure because of the age of the main water line to the house from the street. I don`t want to ruin the pressure washer by providing a very low input pressure.

Should I go with an electric model? Do they need less input pressure?? If I had to guess I would say I have less than 40# of pressure at the hose end.

Thanks for any input.

The standard household pressure is 42 to 50 where I live. We have plenty of water flow and if you`re around 40, it sounds like you have plenty of water flow to the equipment.

I had run a gas one at 35 to 40 psi but my problem was flow (needed 3 gpm so really need a 3+ flow). I have a had a well system that could not keep up (low output well pump and small holding tank.)

This pressure washer outputs 2.0GPM.

pressure is not the problem, volume is what is required which usually between 2-3.5 gpm depending on your washer

So I decided to just keep the gas unit. I went to home depot and bought a gun, wand, quick connects, tips and the foam attachment.

I played with it for a few minutes tonight. The gun works great, has a solid feel to it. The foam attachment works well, I sprayed the garage siding with it. I can`t wait to clean a car now with this, I`m sure I have been missing out with getting crap rinsed off the car before washing.
