Description
The Watts 0887540 2″ First Check Repair Kit restores normal backflow prevention performance in compatible 2-inch preventer assemblies. Installed during routine maintenance in HVAC systems and water supply lines, the kit replaces internal seals, springs, and check valve components. Fitting these fresh internal parts restores a tight seal against backpressure and backsiphonage, preventing non-potable water from re-entering the clean water supply. Replacing these components re-establishes cross-connection control, maintaining rated pressure containment and dependable backflow protection across continuous fluid service.
