Description
The Watts 0887300 First Check Repair Kit 009M2 restores backflow prevention and operates in compatible 1-1/4-inch to 1-1/2-inch reduced pressure zone systems. Installed during routine maintenance in HVAC systems and fluid 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. Removing faulty check components re-establishes cross-connection control, maintaining rated pressure containment and dependable backflow protection across continuous fluid service.
