Copper double check backflow preventer

Product Overview

The Copper Double Check Backflow Preventer is a high-performance, compact device designed to protect potable water systems from backflow contamination. Constructed from durable lead-free copper alloy, it is ideal for residential, commercial, and light industrial applications where water safety and reliability are paramount.

This backflow preventer features a double check valve assembly that ensures fail-safe protection against reverse flow, even in low-hazard applications. Its corrosion-resistant copper construction makes it suitable for use with potable water, while its compact design allows for easy installation in tight spaces.

Working Principle

The Double Check Backflow Preventer operates through two independent check valves:

   First Check Valve: Prevents backflow by closing when downstream pressure exceeds supply pressure.

   Second Check Valve: Acts as a secondary barrier, ensuring additional protection in case the first valve fails.

   Shut-Off Valves: Integrated isolation valves allow for easy testing and maintenance without disrupting the water supply.
