The Winter Duck Plug is the key product in Anderson Manufacturing Company's no-drain winterizing system, designed make it possible to winterize plumbing without draining water.
The Duck Plug's patented duck bill valve allows a large flow of air and water to be blown from return plumbing while simultaneously preventing water from coming back into the lines. This eliminates the need for draining water below returns and 'burping' the lines, making winterizing a much more efficient process.
Winter Duck Plugs also come with an optional yellow cap for a finished look. The heavy duty rubber is resistant to anti-freeze and other chemicals. Winter Duck Plugs are designed to be used with the Big Blue Blower, also available from Anderson Manufacturing.
