• Durable high-strength ABS construction — built to resist chemical exposure, UV light, and long-term water contact.
• Large capacity skimmer throat and basket — handles heavy leaf and debris loads while maintaining flow efficiency.
• Includes basket (without float) and built-in plumbing ports — a complete OEM skimmer assembly for new builds or replacements.
• White finish for a clean, traditional pool skimmer look — matches many pool interiors and decks.

When to Install or Replace

Use or replace this skimmer when building a new concrete or gunite pool, installing a new suction intake, or replacing a damaged/failing original skimmer. It’s also ideal when upgrading to a more modern, higher-capacity surface skimmer to improve debris removal and water circulation.

Installation & Maintenance Tips

• Install per manufacturer and local plumbing code guidelines — ensure slip fittings are solvent-welded tightly and water-level is correct for proper skimmer function.
• Position the skimmer lid flush with pool deck or coping for safe access and best suction performance.
• Regularly check and empty the basket — especially during heavy leaf or debris seasons — to maintain flow and prevent pump strain.
• Inspect skimmer throat and housing periodically for cracks, leaks, or chemical wear; replace if integrity is compromised.
