Applications & Compatibility
This skimmer is intended for use in spa environments—particularly liner and fiberglass spa walls, and new concrete wall systems. Its front access design is beneficial when access behind the wall is limited or when servicing from the spa side. Ensure the wall thickness and piping connection size match the skimmer’s intake port before installation.
Installation Instructions
- Turn off circulation and remove system pressure before servicing.
- Cut or prepare the wall opening to align with the skimmer faceplate and plumbing ports.
- Apply primer and solvent cement or appropriate adhesive to match the spa wall material and pipe type.
- Install the skimmer unit, aligning the gasket and faceplate, secure mounting screws evenly.
- Connect the plumbing to the 1½″ socket or 2″ slip port using proper fittings and sealants.
- Re-pressurize the system and inspect for leaks around the skimmer body and port connection.
Troubleshooting Tips
-
Water level fluctuations near skimmer: Check that the skimmer weir is installed correctly and not obstructed.
-
Air bubbles in spa return pipe: Inspect the skimmer seal and gasket for proper seating and use of recommended sealant.
-
Debris not being collected: Confirm the basket is the correct part, the faceplate screws are tight, and the skimmer opening is not covered or blocked.
Maintenance Tip
At each service interval, remove the skimmer basket and clean out debris. Inspect the weir for free movement and check the gasket for signs of wear or compression. Tighten the faceplate screws as needed to maintain a watertight seal. If the spa is closed for winter, ensure the skimmer and plumbing are drained to prevent freeze damage.
