The included cover, flapper, spring, pin, and O-ring restore dependable valve sealing and smooth operation while extending the service life of the existing valve body.
Pro Tip
Inspect the valve body for debris or scale before installing the new assembly. Cleaning the sealing surface helps ensure proper valve operation and extends component life.
Installation Tips
Turn off the circulation system and relieve plumbing pressure before servicing the valve. Lubricate the O-ring with pool-safe silicone lubricant and verify the flapper swings freely before returning the system to service.
