Watts 887705 Vacuum Breaker Check Valve Kit

Product Description

The WATTS 887705 is a check valve kit designed for use with the 800M4 series pressure vacuum breaker (PVB) assemblies. This kit provides the internal check valve components needed to service or rebuild an existing PVB installation. Pressure vacuum breakers are critical backflow prevention devices installed on potable water systems to protect against contamination caused by back-siphonage. The 887705 is sized to fit 1-1/4 to 2 inch assemblies and weighs 0.3 pounds, making it a compact service part kept on most plumbing service trucks.

This kit is used in residential and light commercial plumbing applications wherever WATTS 800M4 series pressure vacuum breakers are installed. Typical installations include irrigation supply lines, hose bibb connections, and other non-health-hazard backflow prevention applications. Licensed plumbers and irrigation technicians performing annual backflow testing or field repairs will find this kit suitable for restoring the check valve function on installed assemblies in the 1-1/4 to 2 inch size range.
