overnight my water pipes froze and now my house has no running water. how do i fix this? i tried using a blow dryer on it for a while but nothing happened. am i just fucked until the weather heats up?
Run the heat in the house. Warm up the space where the pipes are frozen.
Pipes freeze when the space drops below freezing or when hit by continual drafts from the outside.
To speed things along you can get some heat tape for the pipe. Get a length of tape NO LONGER than the length of the run of pipe. Attach it to the BOTTOM of the pipe and wrap loosely with fiberglass insulation if suggested by the manufacturer.
As long as you get the space heated up the pipes will thaw. Crack open one of the faucets so that when water does start flowing it has somewhere to go. Not full blast, just a trickle.
Pipes usually burst when frozen. In fact you might have this problem and not realize it until the thaw. Though I should note that Ive never seen this problem not present itself immediately.
As for fixing it depends on where the pipe is blow dryer wont cut it. Last time this happened to me it was a down stairs office in our family business. No one used it anymore and the heat was off. I stuck space heaters in the bathroom in question to force a thaw.
You need to familiarize yourself with the mechanisms to cut off the water.
Cause it might get worse before it gets better when you start to thaw. But that is the solution thaw and cut off the water. Leave it off until you can keep the pipe from freezing either insulation or just keeping your heat at a certain level.
Hairdryer or heat gun. Run it along all sections where there is a cold draft of air that froze it. The pipes may be burst, so look for that. Turn your water off if you find cracks so you can fix them without water going all over when it thaws.
At least your sewer didn't freeze off. That is, "no fun".
I had this happen to me twice before, and both times it caused the pipes to burst after the water thawed.
If you don't know how to turn off the main water line to your house, figure that out right now and get on it. Listen carefully for running water, it will lead you to the leak(s).
After you get the pipe's fixed you should look into getting proper insulation for the pipes and walls. In my case, both times it was due to having naked pipes in exterior walls leading hose spigots. Make sure your pipes are wrapped up and your walls properly insulated before you seal them back up.
You either have the heat to low or the pipes are outside exposed in some way without insulation.
I use a mr buddy heater and point it at the wall on low. Not to close, just a couple feet away, you dont want fire. Warm the wall up and it will thaw, if its in the basement or a crawl space do the same but monitor it. Get some heat tape for any exposed pipe and some foam pipe insulation for future use.
This is super common in cold places. People are just idiots when it comes to cold, house design, and water pipes. Like having water pipes running up an outside wall, OUTSIDE the insulation, or through the vented crawlspace OUTSIDE the insulation. That isn't even the beginning.
Design it so that pipes are going through inside walls and ceilings instead of bottom floors and outside walls. Using PEX instead of copper or PVC. Using pipe insulation and/or electrical pipe heating tape. These last two are not needed if the place has been designed correctly. But, pipe insulation is nice to have for the pipes in case the heating is off for a while.
