Protect your pipes from bursts as the thaw arrives

12th February 2021

As temperatures are expected to rise this weekend after a long period of cold weather, South West Water is reminding customers how to prevent leaks caused by frozen pipes thawing out.

A sudden change in temperature can result in water-related issues, such as frozen pipes thawing out and bursting. This can often result in leaks and bursts causing flooding and damage.

To avoid expensive repair bills, South West Water is advising customers to check if they have frozen pipes.

What to do if you have frozen pipes:

1. If you don't have any water check with neighbours. If they still have water, your pipes may be frozen

2. Check pipes for signs of a split – a leak or burst will not occur until the water has thawed

3. Turn off the supply using the internal stop tap

4. If the central heating and any other water heating appliances are already on, keep on. However, if they are currently turned off do not be tempted to switch them on to thaw frozen pipes as this could cause damage

5. Drain the cold water system only by flushing the toilet and opening cold taps over sinks and baths

6. If you don't find any damage, turn on all the taps and thaw the frozen pipe using a warm towel or hot water bottle wrapped in a towel

7. When the pipes have thawed and you're sure no damage or leak has occurred, turn off the taps and slowly switch the supply back using the internal stop tap

8. Check the pipes again now that they are under pressure and check again for signs of damage or a leak before switching on water heating appliances

If you discover a leak or burst pipe, call a reputable plumber immediately. South West Water supports approved contractor schemes and a list of approved contractors can be found on the WaterSafe website or by calling 0333 207 9030.

It’s important to know that any big freeze is followed by a thaw which can cause interruptions to your water supply. Would you be able to access an alternative water supply during a disruption?
