2 Pack 9'' Pool Skimmer Plugs with 2 Pack 1.5'' Threaded Winterizing Plugs, Complete Ice Compensator Kit for Above & In-ground Pool Winterization, Spa Return Line Guard, Includes O-Rings

Features: Engineered for Maximum Freeze Protection Winter pool damage often starts in the skimmer box and return lines where trapped water freezes and expands. Our 9-inch skimmer winterization plug is specifically engineered to solve this problem. When installed in a drained skimmer, its unique design allows it to absorb the crushing pressure of expanding ice, acting as a sacrificial buffer that protects the skimmer's structural integrity. This makes it an indispensable pool skimmer guard. A Complete, No-Miss Solution Why risk incomplete winterization? This kit covers the two most vulnerable points: The Skimmer: 2 long-lasting, 9-inch pool skimmer plug units secure your skimmer openings. The Return Lines: 2 standard 1.5-inch threaded plugs, each with a sealing O-ring, screw securely into your pool or spa return inlets to block water entry. By sealing both ends, you create a dry, protected system that can safely withstand freezing temperatures. How to Use for a Worry-Free Winter Drain the System: Before installation, ensure all plumbing lines and the skimmer are completely blown out and free of water. Install the Plugs: Insert the 9-inch pool skimmer plug firmly into the bottom of the dry skimmer. Screw the 1.5-inch threaded plugs hand-tight into the return line openings, allowing the O-ring to create a perfect seal. Open with Ease: When warmer weather returns, simply remove the plugs. Their robust design ensures they come out cleanly, ready to be stored for next season.
