Water supply line frozen again

Fresh water white hose line has new heat tape's installed and line has frozen twice. These tapes are "Easy Heat" brand and don't seem to be working. Bought the tapes new in October at local Lowe's store at recommendation of plumbing associate who says that "lot's of RV'ers use them. Temperatures here are just a tad under 20 degrees F. We are full time in 5th wheel and must stay put here until next summer when wife retirees and we go on the road. Thinking about using the fresh water tank and adding water daily as it has a built in heater but don't want to chance causing damage to it. What do you all think about his situation?

  • In the twenties I have filled the tank and put an electric heater on low in the basement. Worked well for me. The heater also keeps the floor nice and warm.
  • Heat tape on hose doesn't distribute the heat evenly. I wrapped my hose with aluminum foil first then taped the heat tape on with electrical tape. Walmart sells an aluminum tape that probably would be easier to use. I used heat tape on the hose using aluminum foil down to 15 degrees with no problems when I full timed. Much colder than 15 and the fauset would freeze.
  • Do you have insulation over the tape/hose?
    And yes even if the hose works I would keep the on board tank at least half full.
  • Maybe just get one of the hoses that has the heat tape built in then all you have to worry about is making sure it is plugged in.
  • we've camped in some similar temperatures although not by choice. Didn't have any protection for the outside water hose so did as you mentioned. Put water in tank and used that. I may have turned on the tank heaters, but can't remember. Using water from the tank keeps things from freezing up also.
