Watts 887006 First Check Module 009 LF009

Product Description

The WATTS 887006 is a first check module designed as an internal service component for WATTS 009 and LF009 series reduced-pressure zone (RPZ) backflow preventers. The module houses the first check assembly, which is the upstream check valve responsible for maintaining the pressure differential that keeps the relief valve seated and prevents backflow into the potable water supply. It is sized to fit assemblies in the 1.25 to 2 inch body range. Licensed plumbers and backflow prevention specialists install this component during routine maintenance, annual testing, or after a check valve failure is identified.

This module is used in commercial and residential plumbing systems wherever WATTS 009 or LF009 RPZ assemblies are installed. Common applications include irrigation systems, fire suppression supply lines, and building water service entries where cross-connection control is required by local code. Replacing the first check module restores the assembly to proper operating condition without requiring full replacement of the backflow preventer body.

Installation Notes

Installation should be performed by a licensed plumber or certified backflow prevention tester in accordance with local plumbing codes and ASSE standards. Shut off the water supply and relieve system pressure before disassembling the backflow preventer body. Inspect seats and seals during module replacement and reassemble to the manufacturer torque sequence outlined in the service manual for the specific assembly. After reinstallation, the assembly must be tested by a certified tester before returning to service.
