Simpson Cleaning 82232 Dial-N-Wash Adjustable Pressure Regulator for Pressure Washers, Rated up to 4500 PSI

Awesome way to control the power.

Works great. Easy to use. You can dial any pressure on the fly. If say, you are washing your car you can have a nice easy pressure on the paint then without missinf a beat blast the wheels and wheel wells. If you have a non adjustable pressure washer than this is a cheap and easy solution

I was surprised that this Simpson dial pressure adjustment really worked. I placed it on the bottom of a stubby washer gun, between the hose and bottom of gun. The pictures show it going between the gun handle and barrel, but I did not want to rip apart my well worn spray gun to do that. Instead, I used it on my separate Tool Daily branded spray gun and it is awesome! I personally don't use it on vehicles, but that all depends on the strength of your machine.

Absolutely critical tool if you’re pressuring washing. Fully adjustable flow from about 1/4 all the way up to full pressure. Easy to install and a twist of the dial lets you immediately adjust to the conditions.Only complaint, I wish these would last longer. I’m getting about 6 months before it’s time to replace.My machine runs 4gpm and 4,000psi. Never had and leaks.Will definitely buy again.

I do not see much of a difference on my 2800 psi power washer with the valve fully open or closed. I originally bought a pressure gauge but it did not fit. It may drop pressure I just can not tell how much. I wanted to drop about 1000 psi off my 2800 psi pwr washer. So I just turn the valve all the way down which is supposed to drop about 1000psi. I take it off when not needed.

Works great, exactly what I needed.

I have bought 6 of these dial-n-wash regulators. Out of the 6 only 2 actually lasted a couple of weeks. They are very convenient however when they don't regulate the pressure as designed it is frustrating. If they had a harder plastic turbine on the inside, I believe they would work much better and last longer. I will not be buying anymore of these and that's a shame because I really like them while they lasted.

Same brand as my power washer. Easy to install but didn't quite provide a range of pressure I expected. Low settings was still nearly full. Be careful using in somewhat "fragile" items expecting low pressure. I damaged some screens even though set on the lowest setting.
