1812 SAM: 1800 series pop‑up spray head with 12″ (30cm) pop‑up height & in‑built Seal‑a‑matic check valve. Code RB‑A43930
SKU:RB-A43930
Rainbird 1812SAM pop-up spray head complete with Seal-a-matic non-return check valve. This pops up 12″ (300mm) above its body when water pressure is applied. Use this in association with any Rainbird spray nozzle (VAN, HE-VAN, MPR, or U-Series) or R-VAN rotary nozzle.
The SAM seal-a-matic check valve prevents water from leaving the sprinkler once the system has been turned off. In many instances, without this feature, water can continue to dribble from the sprinkler, causing unsightly and annoying wet areas around the sprinkler. The seal-a-matic mechanism shuts the sprinkler down tight when it is turned off, preventing this from occurring.
1/2″ female BSP thread at the base of the body.
