Installation & Compatibility Notes
Before installing, isolate and depressurize the valve body. Remove the old lid and worn components. Clean the seating surfaces. Install the new O-ring, ensure the new flapper moves freely, and fasten the screws evenly. Tighten to recommended torque. After reassembly, restore flow and verify the valve seals and functions correctly under operating conditions.
Maintenance Tips
- Inspect the valve lid and O-ring annually for cracks, warping or wear.
- For resin pool systems, ensure the flapper is not sticking or showing wear patterns.
- Replace the kit if flow reduction or back-flow is observed—worn flapper or seal may cause performance issues.
- Keep spare kits on hand for fast service turnarounds.
