As we move into the new year and the colder winter months approach, it may become more and more common for pipes (especially external pipes) to freeze over. Boiler Boys London have outlined the safest way to defrost (thaw) a frozen pipe so you can get your central heating back up and running again in no time!
Locate frozen pipe
If you have found that when you turn on the taps in your home and no water comes out, then there is likely to be a frozen pipe somewhere in the system. Take a look at the exposed pipes under the sink, in the basement and around the exterior of the house to see if any appear frozen. Usually, they will be coated in frost or bulging slightly. If one if frozen, it is likely others are too, so check thoroughly.
Open the faucet
Before thawing the pipe, you need to open the faucet that the pipe leads to in order to relieve pressure and allow the water to escape as the pipe slowly thaws.
You should start thawing the pipe near the faucet and work towards the blockage. This ensures the melting ice/steam will be able to escape through the faucet. Starting close to the blockage increases the risk of your pipe bursting, as the pressure builds.
Different thawing methods
The simplest method of thawing is to use a hairdryer or a portable heater to thaw a pipe. If you have a hairdryer that can remain plugged in while reaching your frozen pipe, then all you need to do is to point the heat at the pipe, starting close to the faucet and slowly moving towards the blockage. You should be careful not to let the hairdryer come into contact with the water.
If you would rather opt for a more safer option without the use of any electrics, then we suggest that you use hot towels to thaw your pipe. Dip towels in warm water and wrap them around the pipe to slowly thaw the blockage. Although a safer option, please be aware that this process may take a lot longer than a hair dryer or portable heater.
You can also apply electrical heating tape directly onto the pipe in order to thaw it. This will distribute heat throughout the pipe allowing it to slowly thaw.
What to do if your pipe bursts?
If a water pipe in your home does burst, we advise that you switch the mains water line off immediately, to prevent any more water leaking and causing damage.
