Introducing the Winter Duck Plug, a revolutionary product designed to purge water and air from your lines without the need to lower the water level or risk water re-entering your lines. Featuring an innovative patent-pending duck bill style valve, this plug allows for the effective expulsion of water and air while creating a watertight seal that prevents water from returning into the lines. Specifically crafted for in-ground pools, the Winter Duck Plug seamlessly threads into 1.5” threaded fittings to ensure a secure seal. Constructed from heavy-duty rubber, it withstands chemical exposure and freezing temperatures, addressing these common concerns with ease. For added safety, the plug includes a yellow safety cap to provide extra protection against ice formation.
