Pool Winterizing & Closing Supplies

Closing your pool properly is the cheapest insurance you will ever buy. The right pool winterizing supplies keep water out of your plumbing, ice off your skimmer walls, and debris out of the water you will be looking at next April. PST Pool Supplies carries everything a fall closing needs in one place — winter plugs, skimmer protection, air pillows, water tubes, cover pumps, and closing chemicals for both inground and above ground pools.

Freeze damage almost always starts in the same three places: return lines, the skimmer throat, and the pump and filter equipment pad. Anderson and Technical Products winter plugs seal returns and main drain lines after a blowout, in standard closed, extended, and open styles from 1/2" through 2½" pipe. For the skimmer, an Original Gizzmo, an Aquador faceplate cover, or a blowout plug absorbs ice expansion so the skimmer body does not crack — browse the full skimmer cover and Gizzmo range. Anderson has been manufacturing pool winterizing plugs in the USA for decades; see their line at Anderson Manufacturing.

Above the waterline, an air pillow or water tube does the structural work. GLI and Swimline air pillows from 4' x 4' up to 4' x 15' float under an above ground winter cover and absorb the lateral push of expanding ice, while single- and double-chamber water tubes hold an inground cover down without putting holes in your deck. A cover pump from Little Giant, Superior Pump, Danner, or Swimline then keeps rain and snowmelt off the cover all winter. Round out the closing with Jonas, Pool Trol, or SeaKlear winter kits, polyquat algaecide, WinterPill, and non-toxic antifreeze rated to -50°F. For seasonal maintenance guidance, the Pool & Hot Tub Alliance is a good industry reference.

Order your pool winterizing supplies before the first hard freeze — closing early with the right plugs, pillows, and pumps costs a fraction of repairing a cracked skimmer or split return line in the spring.
