Abstract: A pressure activated seal includes a main wall, side walls connected to the ends of the main wall, and flexible flaps connected to the side walls. The main wall, side walls, and flexible flaps define a main chamber adapted to receive fluid pressure for activating the pressure activated seal to form a seal between opposing adjacent surfaces. The pressure activated seal can be placed between concentric tubes or between adjacent plates, with one of the tubes or plates including one or more orifices leading to the main chamber to allow fluid pressure to activate the pressure activated seal to form a seal between the opposing adjacent surfaces of the tubes or plates.

Abstract: A modular water filter system includes a plurality of media filter tank modules including an underdrain disposed within the filter tank module at the bottom side of the filter tank module, a controller, and a plurality of back flush valves associated with corresponding ones of the plurality of media filter tank modules, respectively.

Abstract: The rotating sprinkler head valve includes an upper assembly with a stationary rigid cone received in a conical interior chamber of a rotor, and a cylindrical shaft extending through the stationary rigid cone and rotor. A lower assembly includes a bottom helix member, a strainer adapter having an internal transverse slotted plate and a rotatable slotted flow plate to permit flow when the flow plate slots are aligned with slots in the internal transverse slotted plate. A base top member includes a downwardly extending inner tubular portion and a lower interior edge surface with a helical lower surface forming an adjustable helical aperture in cooperation with the bottom helix member, and a recessed inner helical lip is configured to receive the upper helical surface of the bottom helix member for adjusting a helical aperture.

Abstract: The telescoping pop-up sprinkler includes a telescoping piston assembly that allows the piston assembly of the pop-up to extend upwards at a greater height than the length of the pop-up sprinkler body. The telescoping pop-up sprinkler has a main body with a piston assembly that includes two or more pistons that engage internally with one another, with stops provided at one end of each piston to limit the stroke of each piston. Multiple internal seals are provided to prevent the bypassing of water around the outer diameter of each piston.
