Applications & Fitment
This skimmer is built for in-ground pools with vinyl or fiberglass shells that require a wide-opening skimmer throat and outside-mount installation. Verify that the pool plumbing supports a 1½″ FIP inlet and that the skimmer opening in the wall is compatible with the wide-mouth design before purchasing.
Installation Instructions
- Shut off the pool pump and relieve system pressure before installing.
- Prepare the pool wall opening, ensuring proper thickness, flatness, and waterproofing around the skimmer flange.
- Slide the skimmer body into place, align the mounting screws, and seal the flange according to manufacturer recommendations.
- Install the collar and cover, adjust the height until flush with the deck or liner, attach the 1½″ FIP plumbing connection and tighten securely.
- Restore circulation and observe for proper water surface suction at the skimmer throat and no leaks at the flange or plumbing joint.
Troubleshooting & Maintenance
-
Skimmer not drawing water at surface: Ensure the collar height is correctly adjusted and the weir is functioning freely.
-
Leak around wall flange: Confirm proper mounting, flange sealant, and that the skimmer body is adequately supported from behind the wall.
-
Debris bypassing skimmer basket: Check that the wide opening is mounted flush, the basket fits properly, and the weir is installed.
Maintenance Tip
Inspect the skimmer basket regularly and clean debris to maintain flow. Check the collar adjustment each season to ensure it remains flush with the deck or liner surface. A properly mounted and maintained skimmer like the SP10851OM extends equipment life and helps keep the pool surface clean.
