The RAIN BIRD A43815 is a 12-inch pop-up sprinkler body with an integrated check valve and 30 psi pressure-regulating module, designed for residential and commercial irrigation systems. The built-in check valve prevents low-head drainage after each cycle, protecting turf and reducing water waste. The factory-set 30 psi pressure regulator protects downstream nozzles and rotors from pressure fluctuations that cause misting, uneven distribution, or premature wear. This unit is installed by irrigation contractors and landscape professionals as part of a zoned irrigation system fed by a backflow-protected supply line.
The A43815 is suited for in-ground irrigation zones where consistent operating pressure and post-cycle drainage control are required. The 12-inch pop-up height makes it appropriate for turf areas with taller grass or ground cover where a shorter body would fail to clear the canopy. It accepts standard threaded nozzles and rotors compatible with the 1800-series platform. Typical installation scenarios include residential lawn zones, sports turf, and commercial landscape beds requiring reliable pressure regulation at each head.
Designed as an OEM-style replacement for 1800-series pop-up sprinkler bodies used in residential and commercial in-ground irrigation systems requiring check valve and pressure-regulation functionality at the head.
Installation is performed by licensed irrigation contractors or qualified landscape professionals. Shut off the irrigation zone valve and relieve system pressure before removing or installing any sprinkler body. Verify that supply-line pressure falls within the operating range of the pressure regulator prior to startup. Follow local plumbing and irrigation codes, and ensure all connections are threaded hand-tight plus wrench-snug to prevent leaks without cracking the body.
