Pressure washer question

[Sasquatch912]

I've been debating about buying a belt drive pressure washer later on but right now I am going to have to wait. I have an old Generac pressure washer that the pump failed on and I am debating about taking the hose and nozzle and hooking it straight up, somehow, to my deep well. The deep well pushes out ALOT of water as I also have a 1 1/2 inch pipe. I am trying to figure how I can run this pressure washer hose to it OR if I need to just get a big hose that is attached to the cut off valve on the well and get an adapter to hook up the pressure washer nozzle to the hose.

I know I may not produce a lot of PSI but my GPM should be higher than my old Generac at 2.3 GPM.

My plans is just to use this deal to clean up my farm equipment and trucks.

Think it will work?

Pretty sure you'd have better results peeing a more powerful stream than well tap pressure pushing through a power washer hose and nozzle. My guess you'd get a flow of one pint per minute as described

Oh this doesn't come out of my deep well like a spigot. Once I open up the valve on the well...it pours out more volume than a spigot ever can. I figured the amount of water coming out will give it a little more pressure coming through the hose and nozzle than a typical electric pressure washer. Or am I wrong?

It wont make more pressure than it does. It will reduce it trying to go thru a hose and little nozzle. Using a big hose and a big nozzle,,, up to a point gives it cleaning units, it uses a lot of water but removes lot of grime. But you cant make more pressure without another pump,.

So, my best bet is to get a pressure washer. I know for cleaning junk the GPM would be more valuable than the PSI to a degree...

Cleaning is measured in units,,, right now he details escape me, gpm x pressure and the pressure is a bit like the voltage in a wire feeder, turn it up a couple doesnt make much difference, multiply if by 2x its 2x as good. Heat adds units.

Volume through a spigot will be significantly different than going through a power washer (PW) hose and something like a .042" nozzle. The high pressure of the PW pump is what creates a higher GPM when pushing water through a small orifice...A well producing 30-50 or even 50-70psi is nowhere close to even an electric PW that produces 1500psi, let alone a big gas unit producing 3600psi. Basically a 50psi spigot produces 1/72 the pressure a big gas PW would generate. It simply takes high pressure to get adequate GPM through a small orifice.


Think about it like this...When you first hook up the hose to the power washer and purge the air before starting, that stream you get is what to expect with the PW hose and nozzle hooked directly to the spigot.
