    What must I use to make sure the extension cord I used is safe?
    Community Answer
    At the very least, plug it into a GFCI protected outlet, or use an extension cord with GFCI protection built in.
  • Question
    Should I heat wrap all of the pipes under my mobile home?
    Community Answer
    Yes. It couldn't hurt.
  • Question
    Do electric heating coils around water pipes only work at a certain temperature?
    Community Answer
    No. They work as long as they are plugged in. Unless you plug in an additional thermostat especially made for the electrical tape warmers, they will turn on only when needed.
  • Question
    What do I do if the pipes are too close to the outside wall to get anything behind them?
    Community Answer
    If your pipes are tight against the outside wall, you definitely have a possible freeze issue. Lay the tape flat on the pipe, taping it with foil tape to hold it in place, then cover it with foam noodles.
  • Question
    Can I use plastic zip ties to secure the heating cable to the pipe?
    Community Answer
    Zip ties should be avoided because strapping them too tight will pinch the insulation, making it thin against the wire, which could cause it to crack over time or damage the wire inside.
  • Question
    Is wrapping a pipe with electrical tape a fire hazard?
    Community Answer
    Generally, no. Heater tapes are specifically designed for that and used in the northern parts of the U.S. during freezing weather. If the pipe is not leaking and the source of the electricity is protected from possible dripping from the pipe, all should be ok.
