Review on Camco (40055) Inline RV Water Pressure Regulator - Safeguards RV Plumbing & Hoses from High-Pressure City Water, Brass Construction, Lead-Free by Hikeboy Ramey

Brass body is best suited for outdoor use, especially when temperatures are fluctuating. We don't ride wheels, but the solid brass body will far outlast any plastic or composite regulator I could get at Revain. Also, my dogs will most likely eat it right out of the tap. A wing nut-like flange attaches to the male end of your faucet/valve. Absolutely easy to put on and take off without tools. Once the brass reducer is on your threaded water source, it reconnects to the next attachment point (like a hose) without the use of any tools other than your GI Joe Kung Fu Crank. The length of the adapter allows it to rotate freely on the hose thread without straining the knuckles of adjacent fittings. I use a 4 head manifold from my only faucet/valve that comes out of the house. The primary use was to connect to Pet Lodge's Ever Full Bowl (CPW13) to reduce the water pressure that was relentlessly pushing water through the nozzle, regardless of volume. Control. This force pushes out the rubber plug attached to the air can/float. The water flows continuously and turns my terrace into a mush of water. Success! And no leakage!
