Pressure Regulators

Pressure Regulators

Pressure regulators reduce incoming water pressure to a set pressure usable by a drip system. A pressure regulator is used when the incoming pressure is too high for the emitters or fittings. The flow rate of the regulator should be matched with the system. Pressure regulation does not take effect until minimum specified flow passes through the regulator.


NOTE: It is recommended that pressure regulators be situated after valves or shutoffs. They may be damaged if left under constant pressure, unless stated otherwise.
