Hayward PLUG WINTER CMPL

The Hayward Winter Plug Complete is designed to seal off pool plumbing lines during the off‑season, helping protect the system from freeze damage and preventing water from entering pipes while the pool is closed. It typically features a durable body with a reliable sealing mechanism—often a rubber expansion design—that creates a tight, secure fit in return lines, skimmers, or other openings. By blocking water intrusion and maintaining an airtight seal, it supports proper winterization and helps ensure the plumbing remains intact until the pool is reopened in warmer months.
