If you do encounter frozen pipes, you must first identify where the pipe is frozen. To do this, you should turn off the main water supply to keep water from gushing into the house once the pipe is thawed. You should then open all of the faucets in your home. If there is no water flowing from any of the faucets, your pipes are most likely frozen near the meter. If you have water in part of your home, the frozen pipe is probably located along an outside wall or uninsulated space. Try to warm the pipes by opening cabinet doors to allow warm air to circulate around the pipes. You can also thaw frozen pipes gently using an electric heating pad, hair dryer, or even a portable space heater. You should never use an open flame device such as a blow torch or kerosene heater. Start thawing your pipes at the section closest to the faucet. The faucet should be kept open to direct water through the frozen area to help with the thawing process.
If your pipes have burst or you see evidence of significant damage, you should contact a plumbing professional as soon as possible.
