Function: Prevents water pipes from being damaged due to high pressure, suitable for campers, trailers, and RV plumbing systems. Double filter design helps prevent the regulator from clogging due to impurities, extending service life. SAFETY: Every regulator is tested to contain less than 0.13% lead, meeting NSFs 0.25% lead-free requirement for safe drinking water. COMPATIBILITY: Features a 3/4 inch garden hose thread with an unobstructed inlet for smooth and steady water flow. Compatible with standard water sources. Inlet strainer helps filter out impurities to protect the valve. ADJUSTABLE: Factory preset to 45 psi; water pressure can be adjusted as needed using a screwdriver. Turn clockwise to increase pressure and counterclockwise to decrease pressure. SCALE DISPLAY: Built-in pressure gauge allows easy monitoring of water pressure, ideal for caravans, campers, and travel trailers. Helps protect RV plumbing systems from high-pressure water damage when connected to city water sources. PRODUCT DETAILS: Adjustable water pressure regulator adjusts incoming pressure to the RV between 45 and 55 psi. Designed for use in standard atmospheric pressure environments with one-way flow direction and straight-through structure. USAGE: Turn off all RV water supplies before adjusting water pressure.
