Installation & Compatibility Notes
Before installation, ensure your filter tank is compatible with a top-mount valve and uses 1½″ plumbing. Shut off the pump and relieve all pressure from the system. Remove the old valve, clean the filter tank closure surface and install the new valve using the supplied O-ring and clamp collar. Confirm proper alignment of the handle and verify all plumbing connections are secure. After startup, rotate the handle through each position to purge air and verify correct flow direction for each function.
Maintenance Tips
- Keep the O-ring lubricated with a suitable pool-safe silicone grease to maintain a proper seal.
- Inspect handle mechanism and port gasket annually for wear or cracking and replace if needed.
- During backwash cycles check for leaks around the clamp collar or valve base; retighten if necessary.
- If the system shows loss of flow or unexpected pressure rise, inspect the valve for internal blockages or worn diverter components.
