Description
The Watts 0794099 Backflow Preventer First Check Valve Repair Kit restores the primary check stage within an 8-inch assembly by replacing the internal sealing and movement components responsible for directional flow control. It includes a disc setup, spring, and sealing elements that maintain proper seating and response under pressure changes. Installed during maintenance of potable water protection units, it allows the existing backflow preventer to maintain separation between upstream and downstream water paths. This kit is used in regulated water distribution lines and pressure protection setups commonly found in HVAC systems-connected hydronic installations.
