If you would like to know how to unfreeze pipes the you should first take a look at our Top Five Ways To UnFreeze Your Plumbing Pipes because that will give you some really effective ways to defrost your frozen plumbing. This guide will show you how to use everything from a portable space heater if your just an average homeowner that wants to do it themselves or if you are a professional plumber and want to use your B tank torch. Either way check out the guide and it is sure to give you some great tips.

In short there are a few things that we can tell you right now before you even get started unfreezing and thawing your pipes. If the pipe that is frozen is a water line you will want to shut the water source off now before the pipe winds up defrosting on its own and if it has damage from the freeze it will start to leak everywhere. This does not mean you have to shut your entire house or building down just locate what is frozen and then use the valve for that fixture or line.

For example, if the lines were frozen on your kitchen sink that was on the outside wall (which by the way is super common in many areas because the water lines were not insulated correctly) and you had a basement, you could go into the basement and shut the feed vales off that should be right under the kitchen. Most plumbers will install isolation valves in many areas of the house to make service calls easy.

Once you have located the water source you can use our handy guide that we mentioned about to unfreeze your pipes with regular household tools and supplies.

Also remember that if a drain line is frozen, you might not want to use that fixture until you unfreeze the actual waste line otherwise you could wind up with waste water or even possibly a sewage spill.


  1. Hello. We live in North FL in a Garage apartment. The water source is a well. I woke up this morning and the toilet will flush and refill but the tub/bathroom sink/kitchen sink all don’t work…no water. First time in 7 yrs this has happened to us. Today is a sunny day but high is only forecast to be in low 40’s and have a lower windchill factor. Any ideas for me? Not really expecting this living near ocean in Florida.

  2. We live in a mobil home and have not had any water for 2 days. It has been cold here for awhile and it has not frozen until now. I think that may be because we were haveing trouble with our ducktwork (big hole from a cat) and it was keeping it warm under there, well i fixed that last week and now its frozen. My thought is if I block off all the vents and let the heat run for a while, will it heat up the underside of the trailer and unfreeze the pipes. Maybe I should get back under and take down one side of the ducktwork and let it warm up the pipes. What do you think?

    • Hi Jamie,

      Sorry to hear about your frozen pipes!

      That could work, or you could get a small electric space heater and put it under the trailer. Make sure that the skirting is closed all the way around the trailer as much as possible to help the heat stay in.

      Let us know if you need more help!
