The Ice Sweeper™ replaces the overflow tube. Simply pull out the overflow tube and replace with an Ice Sweeper™. The basic Ice Sweeper™ is the same diameter as a 2” overflow pipe. A method of extending the normal length is available with notice. Adapters are available for 3” slip drains and 3” threaded drains as in Johnson Concrete Products Company™ troughs. Rubber adapters are available for vertical installation in Ritchie® Water Master™ troughs and Miraco® 6000 series troughs. Superior™ waterers equipped with an adjustable slip drain, require the insertion of a simple metal washer stop. Ice Sweepers™ with 2” pipe threads on bottom are also vailable. When ordering the Ice Sweeper™, knowing the diameter and length of the overflow tube will result in proper sizing.
