What You'll Learn
Using a hair dryer
Before attempting to thaw a frozen pipe, it is crucial to locate and turn off the water at the main shut-off valve in your home. This is because the expanding water can cause the pipe to burst, leading to potential flooding. Once the water is shut off, you can begin the thawing process using a hair dryer.
To start, turn the hair dryer to its maximum setting. If you are using a heat gun, choose a medium temperature setting to avoid melting PVC pipes. Hold the hair dryer a few inches away from the frozen pipe, starting near the edge of the frozen area, closest to the nearest kitchen or bathroom. This allows any steam or water generated by the heating to escape the pipe.
As you apply heat to the pipe, use a piece of sheet metal or aluminium foil behind the pipe as a heat deflector to keep the heat contained in the frozen area. A cookie sheet can also work well for this purpose. Ensure that the water does not come into contact with the hair dryer, and be cautious to avoid any dripping water coming into contact with electrical outlets or bulbs.
Once the pipe is thawed, turn on the faucet so the melted water can drip out. Leave a little water running to prevent the pipe from freezing again. It is important to note that if the pipe springs a leak while thawing, shut off the main water valve immediately until the leak is fixed.

Applying heat tape
Heat tape is an electrical cable, not an adhesive tape, and it works to protect indoor or outdoor metal or plastic pipes from freezing. It is a flexible, flattened cable that typically plugs into a GFCI outlet. It is recommended that you use a heat tape kit for your first installation, rather than raw cable, as the kits come in a variety of lengths and have the plugs already attached to ensure a proper connection.
When installing the heat tape, make sure to read the manufacturer's instructions carefully and follow any recommendations. The heat tape should run along one side of the pipe or tightly wrap around the pipe in a candy cane pattern. Unless the instructions allow it, do not double wrap or overlap the tape, as this could cause it to overheat and short circuit.
If you are using heat tape to thaw a frozen pipe, it is important to be at home during the process in case the pipe ruptures. Start by opening the faucet connected to the frozen pipe to allow water to flow when it starts to thaw. Attach the heat tape to the pipe using electrical tape, ensuring that it does not wrap around the pipe. Connect the heat tape to a heavy-duty extension cord and plug it into a GFCI outlet.
It may take several hours for the pipe to thaw, and it is important to be cautious and follow safety guidelines to prevent fires. Once the pipe has thawed, make sure to check for any leaks and shut off the main water valve if necessary.

Turning up the heat
If you suspect that your pipes are frozen, turn on the faucets to see if the issue is affecting your entire home or just a specific area. If the problem is isolated to one or two faucets, you will need to trace the pipe back from the faucet to find the frozen part of the pipe. Frozen pipes can lead to burst pipes, so it's important to thaw them out as quickly as possible to minimize damage.
One way to thaw a frozen pipe is to turn up the heat in your home. This method can take a while, so be prepared to wait at least 30 to 60 minutes. You can also use a hair dryer, heat tape, or a space heater to speed up the process. If you use heat tape, wrap it around the affected area of the pipe and then plug it in. If you use a hair dryer or space heater, direct the warm air at the pipe so that it hits the frozen part. Even after the water pressure is fully restored, keep the heat on the pipe to ensure that the ice in the line is completely melted.
Another way to thaw a frozen pipe is to pump hot water into it. You can use a jet snake, which pushes a jet of hot water at about 1000 psi. Alternatively, you can use a small plastic pipe to fish down the frozen pipe and then turn on a pump to flush hot water through the blockage. This should eat right through the frozen line. Remember to turn off the main water supply before attempting this method, unless you're very quick!
If you can't access the frozen pipe, you can try to heat the space around it. Grab a couple of space heaters and close up the vents and doorways to trap the heat. You can also rent torpedo heaters to heat the wall from the outside, but avoid doing this if your home has vinyl siding or another material that can't withstand the heat. Be careful not to use too much heat, as this can damage the pipe or create a fire risk.

Using a hot water flush
If you have frozen plastic pipes, you can try to thaw them using a hot water flush. This method is effective and safe, but it can be time-consuming and messy. Before you begin, make sure you have shut off the water supply to your home. You can do this by turning the main water supply valve clockwise to its "off" position.
Next, turn on all your faucets and flush your toilets to drain the water remaining in the system. Place a bucket under the frozen pipe to catch any drips. If the frozen pipe is accessible and it is safe to do so, you can start the hot water flush by pouring hot water over the affected area. Start near the faucet and gradually work your way towards the frozen blockage.
You can also try using a jet snake, which pushes hot water at high pressure through the pipe. This method is faster and more effective but requires specialized equipment. If you are unable to locate the frozen area, access it, or thaw the pipe, it is best to call a licensed plumber for assistance.
Remember to act quickly if you suspect a frozen pipe, as it could burst and cause significant water damage to your home.
