Simpool AGSD-H Standard-Mouth Skimmer Plug – Above-Ground Pool Winter Seal
Part # AGSD-H — a purpose-built skimmer plug designed for standard above-ground pool skimmers. This plug provides an airtight seal that helps prevent freeze damage in the skimmer and simplifies winterizing without draining the pool below the skimmer level.
Key Features
- Fits standard above-ground skimmer openings, typically 5-7/8″ wide × 5-5/8″ high faceplate size.
- Rigid ABS outer plate with an integrated seal designed to lock into the skimmer throat for a watertight, air-tight winter closure.
- Tool-free installation—simply press the plug into the skimmer opening and let the seal expand to grip securely.
- Protects skimmers from freeze/crack damage by isolating the skimmer water column during pool shutdown.
- Reusable season after season for maintenance ease and cost savings.
Typical Applications
This skimmer plug is ideal for above-ground pools that use standard faceplate skimmers (e.g., common 6″ wide skimmer openings) and need a reliable winter seal or temporary closure during service or off-season storage.
Installation & Compatibility Notes
Before inserting the plug, turn off the pump and ensure the pool water level is at or below the skimmer throat as recommended. Clean the skimmer throat and faceplate area of debris. Align the plug and press it firmly into place so the sealing layer sits flush with the skimmer opening. At season start-up, remove the plug, reinstall the skimmer plate, and resume normal operation.
Why Choose This Plug?
The AGSD-H plug offers a convenient, dependable method to winterize your skimmer or isolate it during service. Its strong seal helps avoid costly skimmer damage, reduces labor, and makes seasonal transitions easier for pool owners and service professionals alike.
Maintenance Tips
- Inspect the plug before each use—ensure the seal is free from nicks, deformation or hardening.
- Store the plug in a dry, cool place when not in use to maintain the foam sealing layer’s elasticity.
- Keep the skimmer throat clear of debris during install so the plug seats properly.
- When removing the plug at the start of the season, inspect the skimmer throat for wear or damage and replace if needed.
