The RAIN BIRD A50505 is a 2-inch pop-up sprinkler body with an integrated 30 psi pressure regulator, designed for use in residential and light commercial irrigation systems. The built-in pressure regulator maintains consistent downstream pressure, protecting heads and nozzles from damage caused by high-pressure supply lines. Licensed irrigation technicians and landscape contractors install this body as part of zone-level sprinkler layouts where pressure management is required at the head rather than at the valve.
This pop-up body is suited for turf and ground-cover irrigation zones where supply pressure exceeds recommended nozzle operating ranges. The 2-inch pop-up height makes it appropriate for low-growing turf applications. It is installed in-ground with a matched nozzle and fits standard threaded riser and lateral pipe configurations common in residential irrigation design.
Designed as an OEM-style replacement or new-installation body for residential and light commercial pop-up sprinkler systems requiring head-level pressure regulation at 30 psi.
Installation is typically performed by licensed irrigation technicians or qualified landscape contractors. Shut off the irrigation zone valve and relieve system pressure before removing or installing any sprinkler body. Use Teflon tape on all threaded connections and hand-tighten before applying a final quarter-turn with pliers to avoid over-torquing plastic threads. Verify local plumbing and irrigation codes for backflow prevention requirements before completing the installation.
