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, well below NSF’s 0.25% lead-free requirement, providing safe and clean water flow. COMPATIBILITY: Features a 3/4 inch garden hose thread with an unobstructed inlet for smooth and consistent water flow. Compatible with standard water sources. Inlet strainer helps filter out impurities to protect the valve. ADJUSTABLE: Factory preset at 45 psi; water pressure can be adjusted as needed using a screwdriver. Turn clockwise to increase pressure and counterclockwise to decrease pressure. SCALE DISPLAY: Equipped with a pressure gauge for clear reading, essential for caravans, campers, and travel trailers. Helps protect RV plumbing systems from damage caused by high water pressure. Effectively reduces water pressure when connected to city water sources with high pressure.
