Waterway Flo-Pro II A/G Skimmer Wide Mouth Mounting Plate, White | 519-4110

Waterway 519-4110 Wide Mouth Skimmer Mounting Plate / Faceplate (White, 18-Hole)

The Waterway 519-4110 is a replacement wide mouth skimmer mounting plate (faceplate) used on select Waterway Flo-Pro / Flo-Pro II above-ground skimmer and front-access skim filter assemblies. This plate clamps the skimmer opening to the pool wall/liner gasket stack, helping create a secure seal and a clean, finished skimmer opening.

• 18-hole screw pattern for even clamping pressure and a more consistent seal
• Helps prevent leaks around the skimmer opening when properly installed with correct gaskets
• White finish to match common above-ground skimmer components
• OEM-style replacement part for correct fit on compatible Waterway assemblies

Maintenance Tips

• When tightening faceplate screws, snug them in a crisscross pattern to apply even pressure and reduce leak risk.
• Avoid overtightening—too much torque can crack the plate or distort gaskets.
• Inspect and replace flattened, brittle, or torn gaskets whenever the faceplate is removed.
• Keep the skimmer basket cleaned regularly to maintain steady flow and reduce stress on skimmer components.
