  • SAE threaded test cocks: standard SAE/NPT test cocks and threaded protectors for convenient testing and draining.
  • Serviceable cartridge: top‑access modular cartridge with replaceable seats and captured springs for fast field service.
  • Durability and protection: built‑in freeze‑resistant relief valve, low pressure loss design, and corrosion‑resistant components.
  • Performance ratings: nominal 1 in. size, 150 PSI working pressure and an operating range suitable for common irrigation temperatures.
  • Manufacturer support: compatible repair kits and a 5‑year limited warranty from the manufacturer.

This model is intended for vertical installation with inlet at the bottom and requires clearance for access to test cocks and shutoff valves. It is listed to recognized potable‑water standards (see manufacturer datasheet for full approvals and sizing) and is commonly used by contractors for irrigation, landscape, and light commercial backflow protection. For code compliance, installation and testing should be carried out by a licensed plumber or certified backflow technician; refer to the product submittal sheet for dimensions, weight, and required clearances.
