Product: Pool Skimmer Plug What it does and why you need it Prevents skimmer housing cracks in freezing weather by compensating for expansion of ice and frozen water. Reduces risk of costly skimmer repairs and pool liner damage during winter. Makes winterization simple and reliable with an integrated freeze compensator that absorbs pressure from ice expansion. Durable design lets you winterize repeatedly without deforming or failing, so the skimmer remains protected season after season. Key features and benefits Freeze protection: Inhibits expansion of freezing materials inside the skimmer, protecting the skimmer housing from cracking. Strong ABS construction: Made from quality ABS for a rigid, longlasting plug that resists cold and retains shape over repeated use. Dualsize compatibility: Fits 3.8 cm (1.5 in) and 5.1 cm (2 in) skimmer inlets, supporting large and deep skimmers commonly found in most inground pools. Easy installation: Install quickly once skimmer pipes are fully dry. Tighten by hand—no need to run water under the pool or perform complex winterization steps. Lowmaintenance protection: Once installed, provides continuous protection through freezing conditions without ongoing adjustment. Simple installation steps 1. Drain and dry skimmer pipes and inlet area completely. 2. Insert the Pool Skimmer Plug into the skimmer inlet. 3. Tighten the plug until snug—no special tools required. 4. Leave in place for the winter season; remove when reopening the pool. Practical applications / use scenarios Seasonal winterization of inground pools in cold climates: Install the plug before the first freeze to protect skimmer housings from ice damage while the pool is closed. Shortterm absence or vacation: Secure the skimmer before leaving for extended periods when temperatures may drop, giving peace of mind without daily checks. Routine pool maintenance and repairs: Use as a replacement plug after skimmer service or while working on pool equipment to keep the opening sealed and protected. What to expect Reliable physical protection for skimmer housings during freezing conditions. A simple, repeatable winterization step that reduces the chance of expensive repairs. Compatibility with most ground pool skimmers thanks to the two supported inlet sizes. Note Ensure skimmer pipes and inlet are fully dry before installation for proper sealing and performance.
