Pressure regulators are designed to limit the pressure in the irrigation system. Too much pressure will blow fittings off and can cause sprinkler nozzles to become too ‘misty’, reducing the evenness of coverage.
The screw adjustment on the pressure regulator allows the pressure to be altered. Pressure regulators do need some flow to operate.
