I’ve been dreaming of a better solution for an expensive power washer. Ultra Pro 5 works great with my standard washout nozzle, but I plan to begin using 10 mil Ultra Vinyl which requires a little more washout pressure.

This little unit is home made, but don’t let that fool you. It runs on air pressure and does an absolutely AWESOME job! Besides that, it can fit in the top drawer of my desk.

See the two photos of me holding the unit. The first one is just standard water pressure, the second one is of the gun with only 20 lbs. of air pressure. The sweetest part of this thing is that I can control both the pressure and the volume of the water.

With the air hooked up, I simply pull the trigger (to release the air) and slowly open the handle on the hose shut off valve. The water will begin to surge slightly, but it will even out when just the correct amount begins to flow. I know the flow is correct when it produces just a little bit of a sting on the back of my arm.

I use a standard air nipple for the nozzle. The ¼ n.p.t. thread fits the tee perfectly and has an approx. orifice size of .200”. It produces a round spray pattern that does a remarkably fine job. I estimate that my washout time is only one-third of the usual time with the old sprayer. That means 66% LESS time for the resist to erode.

No water back flows into my air lines either.

Most all of these goodies can be obtained locally. As you can see, I didn’t break the bank either!

The air goes into the base of the handle, where the water would normally enter if it were hooked up to an actual pressure washer. The water is turned on and off at the end of the hose using the shut off valve.
