Please note: Irrigation pressure regulators need outflow and back pressure to regulate the pressure within your irrigation system. With no water flowing through the regulator, the inlet and outlet pressures will measure the same. To verify the pressure maintained in your system, you will need to place a pressure gauge at the end of one of the zones. Turn the zone on, let it pressurize, and once the lines have filled and emitters begin to flow then take the reading. This will reflect the working pressure within your system. Features: Low hysteresis and friction loss Can be Installed above or below ground Large flow path resists plugging No external metal parts to corrode Special note: This pressure regulator is not designed to operate under static (constant) pressure. It must be installed after any valves or timers to operate correctly. Using this item under static pressure will eventually weaken the internal spring and cause the regulator to fail.
