Description
The Watts 0794098 6″ Backflow Preventer First Check Valve Repair Kit restores the internal sealing and flow-control mechanism that permits water to move in one direction while blocking reverse flow within the valve assembly. Its disc, spring, and sealing elements rebuild the check mechanism, allowing forward water flow while preventing reverse movement through the unit. Built into water distribution networks associated with HVAC systems, this kit maintains the intended directional flow within the protected piping circuit. The service components are fitted inside the valve body and secured in the designated locations so the assembly resumes normal operating conditions.
