Winter Duck Plugs - Save Time - Save Water - Save Covers!

Designed for use with inground pools, the unique design of the Winter Duck Plug allows you to prepare your plumbing lines for the winter without draining the pool first! The patent-pending "duck-bill" valve allows a large flow of air and water to be blown from the return plumbing but does not allow water to flow back into the lines.

Features:

• No need to drain your water level below the return jet(s) when closing or winterizing your pool
• Unique double seal system provides a water tight seal on all 1.5 inch threaded fittings
• Includes safety cap for protection against ice
• Heavy-duty rubber construction is resistant to anti-freeze and other pool chemicals

Warranty Period: 1 Year Manufacturer's Warranty
