Winter Skimmer Covers, Plates & Gizzmos

The skimmer is where most winter pool damage actually happens. Water sits in the skimmer throat, freezes, expands, and splits the housing — a repair that means cutting concrete or pulling a liner. A winter skimmer cover, faceplate, or Gizzmo gives that ice somewhere harmless to go. PST Pool Supplies stocks all three approaches for above ground and inground skimmers, so you can protect the skimmer whether you drain below it or leave the water level up.

The Gizzmo is the classic solution: a hollow threaded bottle that screws into the skimmer's 1½" outlet and crushes inward as ice forms, absorbing expansion instead of transmitting it to the skimmer wall. The Original Gizzmo covers 1½" MPT, and the Super Gizzmo handles 1½" or 2". Compensators work the same way for above ground and Ultimate 1½"/2" MPT applications. Numbered winter plugs with integrated blowout valves (#8, #9, #10, #13) seal the skimmer line while letting you re-blow it later without pulling everything apart.

Aquador faceplate covers take a different approach — they seal the skimmer opening at the pool wall so the skimmer body stays dry all winter and you can keep the water level up near the tile. We carry complete Aquador kits and replacement lids for above ground standard, wide mouth, Doughboy and Lomart skimmers, plus inground kits for Hayward SP1084 and SP1085 and Aqua Genie. If you would rather block the throat directly, winter skimmer plugs are sized to specific openings — 6" and 8" round standard, 11.5" x 5-3/16" and 15-3/16" x 5-3/4" wide mouth. Pair with matching winter return plugs and see the complete pool winterizing supplies range. For skimmer parts outside of winter, browse our pool skimmer parts. Industry closing guidance is published by the Pool & Hot Tub Alliance.

Protect the skimmer before the first freeze — a winter skimmer cover or Gizzmo costs less than thirty dollars, and a cracked skimmer housing costs hundreds to replace.

Frequently Asked Questions

What does a Gizzmo actually do?
A Gizzmo is a hollow plastic bottle that threads into the skimmer's 1-1/2" outlet and stands up inside the skimmer throat. When water in the skimmer freezes and expands, the Gizzmo's thin walls collapse inward and absorb that expansion — so the force goes into a $15 piece of plastic instead of your skimmer housing. It also seals the plumbing line at the same time. Use the Original Gizzmo for 1-1/2" MPT and the Super Gizzmo where you need 1-1/2" or 2".
Should I use a Gizzmo or an Aquador skimmer cover?
It depends on where you leave your water level. A Gizzmo assumes you drain the water below the skimmer, and protects the empty skimmer from any water that still collects in it. An Aquador faceplate seals the skimmer opening at the pool wall, which lets you keep the water level up near the tile all winter — better for vinyl liners and for solid covers that need water support. Many closers use an Aquador on the wall and still put a plug in the skimmer line for redundancy.
How do I know which Aquador kit fits my skimmer?
Match by skimmer model and opening size, not by pool brand. For above ground, we stock kits for standard skimmers (AQ1090), wide mouth 11.5" x 5-1/8" (AQ1010), Doughboy (AQ1020) and Lomart. For inground, kits are model-specific: Hayward SP1084 (AQ1084), Hayward SP1085 (AQ1085) and Aqua Genie. Measure your skimmer's faceplate opening and check the model number stamped on the skimmer or faceplate before ordering. Replacement lids are sold separately if your kit body is still good.
What size winter skimmer plug do I need?
Measure the skimmer throat opening at the pool wall. Common sizes are 6" round for most above ground standard skimmers, 8" round for most inground standard skimmers, and rectangular wide mouth openings at roughly 11.5" x 5-3/16" (above ground) or 15-3/16" x 5-3/4" (inground). We also stock a 5-3/4" x 5-1/4" size for some above ground skimmers. Measure the opening itself rather than the faceplate, and order the plug that matches those dimensions.
Can I skip skimmer protection if I drain the water below the skimmer?
Not entirely. Draining below the skimmer removes the standing water, but rain and snowmelt still find their way into the skimmer throat through the cover and the deck lid over the winter. That water collects in the bottom of the skimmer, freezes, and can still crack the housing — which is exactly the failure a Gizzmo or blowout plug is designed to prevent. It is the cheapest single item in a closing kit and the one that protects the most expensive repair.
