Confirm Before Ordering
Please confirm your existing valve brand, model, size, and part number before ordering. Check valve replacement parts can look similar but may not fit every valve body. Match the valve body and current flapper assembly before purchase.
Installation Note
Shut off pool equipment and relieve system pressure before servicing any check valve. Inspect the valve body, lid, gasket area, and internal sealing surface before installing the replacement flapper assembly. Professional installation is recommended if the valve is part of a complex pool/spa plumbing system.
Warranty & Compatibility
Compatibility depends on the existing valve body and installation. Installed plumbing parts may not be returnable. Always verify fitment before opening or installing the replacement assembly.
