Description
Watts 0888832 First Check Kit 8″ To 10″ renews the primary check section of Series 994 backflow preventers by replacing internal sealing and moving parts that become damage through regular operation within HVAC and water distribution systems. The replacement components allow the check mechanism to open during normal forward flow and close securely if reverse flow occurs, preserving proper one-way movement through the assembly. Each part is matched to the original dimensions for accurate fit and smooth operation inside the valve. Routine installation of this kit restores dependable backflow protection and maintains stable flow conditions throughout the connected piping system.
