WATER DRAIN PLUG AND O-R KIT

The kit includes a drain plug plus a matching O‑ring gasket, designed to seal the drain port on a pool or spa filter housing or pump. When installed properly, the plug closes off the drain securely and the O‑ring ensures a watertight seal — preventing leaks during normal operation. When you need to service, empty, or winterize the system, removing the plug allows water to safely exit through the drain port, making maintenance easier without disassembling the entire housing. This simplifies tasks like cleaning, sand replacement (in sand filters), or winter prep, and helps protect the equipment from internal pressure build‑up or accidental water retention after shutdown.
