I recently moved into a mobile home and with the temperature dropping below freezing I wanted to make sure my water line was protected. It has a electric heat tape wrapped around it with insulation. A short, 3-4", section of the insulation wrap is missing. Should I be concerned about missing a short piece or will the heat wrap still keep the water warm enough to prevent freezing. The skirt is in place under the home.

  • Hello, and welcome to Stack Exchange. It's hard to know, as there are so many variables (water temperature, usage; air temperature, wind; etc). Sounds like you'd at least feel more secure if you fixed it. – Daniel Griscom Nov 10 '18 at 22:07

Welcome to DIY! You should replace the missing piece of insulation. The insulation works with the heat tape to prevent freezing.
