As the water level drops, the float opens until filled with water allowing for a complete PECK FREE solution for your birds! PVC Pipe Installation The threaded cup allows for connection to PVC pipe, allowing the drinkers to be placed at virtually any height required for different sized birds. Gravity Bucket Installation The wing nut provided allows to mate the drinker cups to virtually any water storage container such as the common 5 gallon bucket. A rope or chain to support the bucket allows to modify the height required as birds grow larger in size.
