Plan Ahead to Prevent Waterlines and Equipment from Freezing


Iowans should make sure the water supply to their house and livestock buildings is well protected from freezing.
The three most common approaches, according to Shouse, are adding heat with a heating device, insulating to conserve heat and adding heat by bringing in warm water.
The most basic advice is to empty all water lines that can be emptied, including hoses, sprinkler lines and pasture water lines. Insulation can be added to protect outside walls, and interior insulation can be removed, to allow heat from a heated building to reach the pipes.
In places that are unheated, Shouse gives options such as a small electric heater or heat lamp, or long strips of electrical resistance heating cable (heat tape).
