Winter Duck Plugs (Case of 100)

Allows plumbing lines to be winterized without draining the pool. 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 back into the lines.

HOW TO USE:

• Install plugs into all lines. The double-seal system provides a water tight seal at the face plate or inside the fitting.
• Use a blower to clear all lines. The Winter Duck Plug provides adequate back pressure to allow all returns to be cleared at the same time without "burping."
• Once all returns have been bubbling for several minutes turn off the blower. Water will not enter the pipes from the pool.
• Add optional antifreeze to lines and turn on the blower again until you see some antifreeze blown into the pool.
• Install optional yellow caps for a finished look (caps are not necessary to prevent water from flowing back into lines).
