Insulated extension tube keeps your water line from freezing! Highly insulated tube shields incoming ground water from cold as it passes through the frost level. Polyethylene construction ensures years of trouble-free use. One 30-inch tube and 3 feet of 12-inch plastic drainage tile provides a sufficient heat well in most locations. For northern locations, two 30-inch heat tubes may be required. Outside dimensions are 14” X 30”. 2” Insulation.
