1804 SAM: 1800 series pop‑up spray head with 4″ (10cm) pop‑up height & in‑built Seal‑a‑matic check valve

SKU:RB-A43905

Rainbird 1804SAM pop-up spray head complete with Seal-a-matic non-return check valve. This pops up 4″ (100mm) 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.

Features

All 1800s

  • Co-molded wiper seal provides unmatched resistance to grit, pressure and the environment
  • Constructed of time-proven UV-resistant plastic and corrosion-resistant stainless steel parts, ensuring long product life
  • Precision controlled flush at pop-down clears debris from unit, assuring positive stem retraction in all soil types
  • Two-piece ratchet mechanism allows easy nozzle pattern alignment and provides added durability
