The Drip Store’s line of adjustable pressure regulators is available in 3/4" and 1" FNPT. The adjustable pressure regulator is used in applications that demand accurate and reliable control of pressure no matter what fluctuations occur in the supply line pressure or flow rates.

    • Installation for Adjustable Pressure Regulator

      Use the pressure regulator for your irrigation system and install the device after the filter. Choose the correct thread (hose or pipe).  The pressure regulator should never be installed on a main line where the device is under constant pressure. In this situation, we recommend installing the pressure regulator after the valve. 

      To adjust the pressure use a screwdriver and turn the screw under the cap: + to raise the pressure and – to lower the pressure.

      Note: A common misconception is that turning a valve or faucet down will reduce the downstream pressure, but this is incorrect; turning the water down only reducers the flow, not the pressure. The pressure remains high.
