ok im updating this.

i have an idea how to pressure water make a hose hook up to a check valve then a copper pump. water fills pump and then you push down goesa through a second check valve and into the gun until it is high pressure.

2nd idea dis assemble a pressure washer handle to a fitting hook the fitting to the gun then pressure the gun. like a 2400 psi one. will that be way to high pressure?

just some ideas

lol, might as well just buy a pressure washer i don't know why you think that you can make, or even pump for that matter a 2400psi pump. especially out of copper

copper is usually rated for 3ksi or more. I would like to submit an alternate design, one built by D_Hall (the guy with the massive 29" bore hybrid)

The amount of energy needed to provide a stream at that pressure is very high. This is why most pressure washers are several horsepower.

Water under very high pressure forced through a small orifice rapidly breaks up in air. Ever notice that you can squirt further with a garden sprayer than you can with a pressure washer? Most pressure washers are unable to squirt water further than about 20-25 feet. The water stream breaks up into fine mist.

Anything over 250 PSI is a waste of pressure. Larger orifices help, but then you need a firetruck pump of several hundred horsepower.
