Pipe-thawing options: There are several things you can do to thaw your home's pipes. Here's a list: Probably the most popular and safest pipe-thawing option is to use hot water. Wrap and secure heavy towel or burlap bag around pipe to concentrate and hold heat against it.
Open a Hot Water Valve
First, turn off the main water valve to take the pressure off the frozen pipe. Then, open multiple hot water outlets if possible (including the one closest to the frozen pipe). By opening faucets, water will have a path to flow as the pipe unfreezes.
In many cases though, using the right heating tools can unfreeze your pipes in a matter of 30-45 minutes.
You can try to thaw a frozen pipe by increasing the temperature in your home. Turning the thermostat up may help the ice blockage to melt. Not only will you have frozen pipes, but you may also start a fire. It can also cause the water inside the pipe to boil which will cause an explosion.
Keep the faucet open. As you treat the frozen pipe and the frozen area begins to melt, water will begin to flow through the frozen area. Running water through the pipe will help melt ice in the pipe.
Pipes will eventually unfreeze on their own naturally, but this takes far more time and before thawing occurs the freezing could become much worse. This could eventually lead to the pipe bursting and causing significantly more damage. It's better to proactively thaw a frozen pipe size than let it persist.
Tip #7: A Thaw Machine Will Be Your Savior
It's exactly what it sounds like: a portable device that plumbers use to thaw pipes quickly.
The job goes more quickly by pouring hot water or a mixture of vinegar, baking soda and salt water down the drain. Space heaters, hair dryers and heating pads are highly efficient tools for unfreezing a drain pipe. If a frozen drain line ruptures, turn off your home's main water supply.
Turn off your water supply: When a pipe freezes, it's crucial to shut off the main water supply for the property. If the frozen pipe bursts, the leak may not be noticeable until the water inside it thaws. Turning off the water supply is essential to limit water damage.
Prevent Frozen Pipes
Moving water keeps pipes from freezing. Find shut off valves for emergencies. Insulate pipes in unheated areas. Open cupboards and vanities to warm pipes.
A foul smell from the drain or faucet is a less-obvious warning sign. Odors are unable to filter out of the frozen pipe and instead are forced back into the home's faucet. No water or a slow trickle when a faucet is used. Whistling and banging coming from pipes, or strange bubbling sounds when you flush a toilet.
Thawing in a hot-water bath
Defrosting in cold water is faster than fridge defrosting, and is the standard quick-thaw advice. But new research has shown that using hot water (which the USDA does not currently recommend) is an even speedier and safe way to defrost smaller pieces of meat (an inch thick or less).
Your pipes will eventually begin to thaw on their own once the temperatures rise above freezing.
If you suspect your water heater may be frozen, touch the outside of the unit with your hand until you locate a spot where it's ice cold. If you don't find such a spot on the tank or tankless unit, you may have ice in the pipes leading in and out of the unit rather than in the heater itself.
Possible Issue: One of the most common culprits for this predicament is a malfunctioning differential valve. This valve is responsible for controlling the flow of hot and cold water in your plumbing system. When it's not functioning correctly, it can lead to an imbalanced water supply, leaving you with cold water only.

Don't dump any chemical drain cleaners down either, as it likely won't make it through the frozen blockage and it will just sit in the pipe. The acid from it could start to corrode over a short time. If you want to take some boiling hot water and dump that down, it could potentially help a minor problem.
It will take roughly 30-40 minutes of using a heat source to thaw exposed pipes. If the pipes are enclosed it will take longer for heat to penetrate the insulation between your heat source and the pipe.
Burst pipes will need to be replaced and a plumber is best equipped to handle the job. The average hourly plumber rate is around $330, depending on where you live and the size of your job. As long as your frozen pipes haven't burst, a plumber will likely charge a flat fee of around $100 to thaw them out.
Should You Drip Faucets In Cold Weather? Yes, according to the Red Cross, the short answer to that question is you should.
Pipes typically burst when exposed to extremely low temperatures for an extended period of time (anywhere from 1-3 days depending on temperature). This is especially true for pipes located on exterior walls. A frozen pipe is likely to burst when any water or liquid trapped within it freezes and begins to expand.
Pipes: Turn off water supply to the house and drain pipes to protect them from freezing. You can empty pipes by running the water and flushing the toilets after the water has been turned off. After draining the pipes, it is a good idea to leave the faucets open to prevent pressure build up from any water that remains.
Turn on all faucets: Checking each faucet in your home will help you narrow down your search. The faucets that have little or no water pressure likely have a frozen pipe in their supply line. If every faucet is showing low water pressure, the frozen pipe may be near the water meter.
