Installation & Maintenance Tips
- Always shut the pump off and relieve filter pressure before opening a multiport valve.
- Clean the lid O-ring groove and the mating surface before reassembly. Dirt and sand can cause leaks and premature O-ring wear.
- Lightly lubricate the O-ring with silicone pool lube (do not use petroleum-based grease).
- If the valve handle feels rough or positions don’t “index” cleanly, inspect/replace the spider gasket and internal sealing surfaces as needed.
- Never change multiport positions while the pump is running—this can damage the gasket and internal components.
