Pouring hot water on frozen pipes. While it might seem like a good idea, in theory, to pour hot water down your pipes to unfreeze them, it likely won’t yield the results you’re hoping for. For short strands of pipe partially blocked, and very hot water, it might. Freezing pipe to repair it.

Once you’re finished, toss that hot and salty water down the drain, where it will hopefully thaw. When temperatures plunge, let faucets drip to prevent hot and cold. Pour salt into the hot water until you see that the salt is not dissolving.

Use a space heater, heat lamp or hair dryer to thaw the frozen. Unless the frozen point is very close to where you are pouring the boiling water. The hot water usually freezes on the outside of the pipe and the torch can cause frozen.

Turn up the thermostat, and circulate warm air through every room by leaving interior doors open. You may pour hot water into a frozen air conditioner with no potential issue. Use a blow dryer to thaw the pipe.

Frozen pipes will be full of ice. Keeping the faucets open will help relieve pressure and allow the water to escape once the pipe begins to thaw. In most cases, you can unfreeze a frozen drainpipe by pouring hot water down it.
