The adjustable arc spray nozzle allows adjustment of the spray arc, the radius, and flow of the water spray provided by the nozzle. The nozzle includes a top member, a base member, and a discharge orifice defined therebetween. A rotatable external upper collar controls the radius of the pattern, an internal helix member controls the arc of the spray pattern, and an internal flow adjustment screw and an optional rotatable external lower collar control the flow of the nozzle.

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.

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.
