Keep your bird bath full of fresh water with the Allied Precision KozyFill Automatic Bird Bath Filler. Without electricity or batteries, the Kozyfill refills your bird bath only when water is needed. Simply attach the mounting clip to any bird bath and watch as air pressure forces water from the reservoir to rise to the same height in the bird bath. This fully assembled reservoir comes complete with a spigot Y-coupler with shut-offs, 50' of tubing that can be buried, if desired, and a 36" mounting pole. Never have to carry water to your bird bath again with the Allied Precision KozyFill Automatic Bird Bath Filler. One year warranty.
