ABSTRACT:
A pop-up sprinkler which includes a housing, a riser in the housing movable between an extended position in which the riser extends from the housing and a retracted position in which the riser is retracted from the extended position and a pressure regulator in the riser. The pressure regulator can be constructed as a cartridge or separate unit and installed in the riser. The riser has an aperture adjacent the pressure regulator and the aperture is between first and second axially spaced seals in the extended position so as to reduce the likelihood of clogging of the aperture. A dirt tolerant wiper seal is mounted on a movable valve tube of the pressure regulator and a pressure activated seal is provided between a valve seat of the pressure regulator and the valve tube.
