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

For some reason the front faucet was plugged in before the house water pressure regulator and I kept blowing the sprinklers. peaked at 157 psi. Bought this Camco RV inline water pressure regulator, attached it to the water pipe and retested with a pressure gauge on the outlet end of this regulator. 60psi on the nose as advertised. (Note: photos show fewer before-and-after measurements. Apparently, for some reason, the city's water pressure is lower after dark.)
