How to Find the Area and Unthaw Your Frozen Pipes
Items You May Need
- Heat tape
- Heat lamp
- Hand held hair dryer
Step By Step Solution
- 1By checking all the faucets in the house, you can figure out where the freezing has occurred. It's the pipes on the outside of the house, that freeze up first, especially the north facing wall, so if your shower is on an outside wall, or your sink, that's a good place to start. If you discover the problem only exits with one faucet, then you know the problem is in the pipes under that sink. If the problem extends to all the faucets, the most likely place is where the water comes into the house. This would be either through a basement wall or in the crawlspace under the house.Isolate the problem.Advertisement
- 2This will not only let you know when you have succeeded in thawing your pipes, but also when the water flowing will aid in clearing all ice out of the pipes.Open all faucets.Advertisement
- 3Once you've found the site of the freeze, you can apply heat and thaw out the pipe. How long the pipe has been frozen will determine how far the freezing extends. Usually, if a pipe has frozen overnight, the entire length won't be frozen. For maximum efficiency, start at the most likely place the freezing occurred. You should be able to determine this by examination of the areas exposed to cold or the wind.Thaw the pipe.
- Use a hand-held hair dryer to thaw the pipe.
- Aim a heat lamp at the pipe and let it do its work.
- 4Be patient - it may take an hour or more to thaw frozen pipes safely.
- 5When the water is running again, you can stop using the hair dryer, or put the heat lamp away, and let faucets run for a few minutes.
- 6When the temperatures are expected to be uncommonly low in your area, take the following precautions.A little preventive home maintenance can prevent frozen pipes in the future.
- Leave faucets dripping.
- Wrap vulnerable pipes with heat tape.
- Wrap pipes with insulation (year round).
- If pipes go through an unheated garage, leave the door from garage to house open.
- Going to be away from home for several days? Turn off the water and drain pipes to prevent freezing.
- Keep cabinet doors open to expose pipes under sinks to more warmth.
Tips & Warnings:
- If you use heat tape, when you wrap the pipes, don't overlap it.
- If you use a heat lamp, do not place it anywhere near flammable materials and do not leave the house while it is still turned on.
- Do not place a heat lamp directly below the pipe. When the pipe thaws out it may leak onto a lamp positioned underneath it, which can cause a fire, due to it shorting out.
- Don't leave the house until the pipes thawed, and water is running freely. When pipes freeze, there's always a chance they'll burst - and if you leave the house without knowing for sure they haven't, you come home to a nightmare.
- Don't risk using a blowtorch or any open flame.
Questions and Answers
Do you leave the faucet on when thawing a frozen pipe in wall overnight?
Yes, this can help your situation to prevent the ice from forming. Leave a faucet on in order to keep it from freezing as easily. If you leave the water - just a slight drizzle - it will keep it from freezing as easily during a cold night, because moving water has a lower freezing temp. If the pipe is already completely frozen then turning water on may just cause it to burst as the water builds up pressure behind the ice. If the pipes are thawing themselves out, it's recommended to leave the cabinet doors open with the heat on in your home in order to allow the pipes to thaw out safely.
A lot of people suggest you do just the opposite - turn the water off to the part of the house that contains the frozen pipe, or to the entire house. The ice might be acting as a plug, and the rush of water that comes when it thaws, might cause leaks or a burst pipe.
How long will it take for pipes to thaw?
This depends on how badly the pipes were frozen. A moderately frozen pipe might take up to two hours to thaw, just from the heat of the house, however taking action, my help avoid a burst pipe.
There is no real solid answer I can give you on this. The amount of variables involved would be too high. It all depends on which pipes in the house are frozen. Whether or not they are above ground level makes a big difference. Overall the location of the pipes in the house both vertical and horizontal, as well as the temperature and amount of sun all have an effect on the thawing time.

Should I let frozen pipe thaw out by itself?
Yes, it is recommended for you to allow the pipes to thaw naturally, without applying any water or extra techniques for this can cause the pipes to burst, which can cause more harm to your pipes, damage to your home and put a dent in your wallet.
It's totally fine for you to let it thaw on its own, but it will depend on the severity of how frozen the pipes are in this situation. If you are not in a rush then you can allow them to thaw out on their own, also if the pipes are frozen to the point the pipe is cracking then you will need to replace the pipe immediately.
How to fix a frozen water pipe if the water is frozen in the pipe leading to only one sink? Do I need to turn off the water for the whole house?
No, it is not necessary. If the pipe you're talking about goes down to the drain other than the pipe that the water comes from in this situation. If the pipe you are talking about is not used to direct water to the faucet then you will not need to turn off all the water in the house.
No, if the pipe is only leading to the sink there will be no need to have to turn off the water to the whole home. But understand that the pipe can still burst and cause a problem if not attended to whether or not the water is on or off.
Is it safe to leave the house unattended with a frozen pipe? #18?
No, depending on how frozen the pipes you may in fact have an issue where your pipes will burst thus spilling water all over the house non stop with no one to help cut the water off or change the pipe once it starts spilling out.
No, you should not leave frozen pipes unattended. You should always try to ensure that you have adequate heating to ensure the pipes don't freeze. If they freeze bad enough, it may end up leading to the pipes bursting the next time someone tries to turn them on.
Can a pipe freezing cause the pipe to burst?
Yes, depending on the severity of the freezing, the pipes can in fact burst. This happens when the pipes freeze without being attended to properly to thaw them out. This often happens when pipes freeze in people's homes without them knowing it's happened. Later on the pipes are founded to be burst.
Can you put heat tape inside a pipe to thaw it out?
Absolutely you can, this will be your last option if the other methods of thawing you're frozen pipes aren't working. This tape will come in handy, but in order to apply this tape, you must first ensure that you are on the right spot and apply the exact amount of heat needed to thaw the frozen pipe.
I noticed that my pipes in basement kitchen are frozen, and water is not coming out of the faucet.
Those pipes are against the exterior wall, and I am heating them almost 8 hours
It can take up to 12 hours or more to unthaw exterior wall pipes, especially if the ground is frozen solid against the exterior wall and your basement is not insulated. Make sure that the taps are open and in the future drip the faucet on super cold days.
I live in the country in a mobile home. Will my pipes thaw on their own?
My pipes have been frozen as of Sunday morning. I have a heating lamp in my pump house and I'm able to get water from the faucet located in my pump house. None of my pipes have busted, so that is good. My question is - will and can my pipes unfreeze on their own?
Eventually they will thaw on their own when the weather warms up. The pump house heating lamp is only heating the pipes. Close the pump and your frozen pipes are further away. If the weather is going to warm up soon, you can wait it out. You still could have busted pipes though, especially if the weather warms in the day and then drops significantly at night.
How long to keep water running in kitchen after plugging in the heat tape?
Unknown to me, the heat tape on the pipes was unplugged by relatives. In the nick of time, I got a trickle running from the kitchen faucet, which now has been running for 3 days almost non stop. This faucet is on an outside wall. Yesterday I accidentally shut it off for 4 hours, and again, in the nick of time, I got a trickle running from the kitchen faucet. Just now I discovered the unplugged heat tape and plugged it in. How will I know if a pipe is frozen or not and when I can shut off the kitchen faucet trickle? Thank you.
When your taps are wide open for maximum flow, and the flow is consistent for at least two minutes, your pipes are not frozen. The heating tape should keep your pipes flowing, even if it is shut off for a few hours.
My water is not working I bought a space heater to put in the room. Where should I put it?
Where I think the problem is, I just am worried that it may get too hot, does that matter? I have tried: Have faucets open and space heater where I think pipes may be frozen. I think it was caused by: Was away for the weekend and it was very cold
The pipes will not get too hot. Keep an eye on the area with regular spot checks just to monitor any fire risk from the space heater. Your pipes carry hot water from the hot water tank and most space heaters do not get to a temperature above 90 F.
Hi, It is a single handle faucet in the bathroom. The hot water (Left) runs but the cold (Right) is frozen and the toilet won't fill. Where do I put the handle to keep the water running until it thaws? Do I position the handle to the cold water side even though nothing is coming out? I opened the vanity doors. Thank you.

Position the handle in the middle for lukewarm water if the pipes were operating normally. You may need to check the pipes in your basement and look for burst or frozen pipes that need to be thawed.
