Why our pipes burst

Last reviewed:

We’ve over 20,000 miles of water pipes – enough to wrap around the moon twice – and 60% of these are cast iron. Many of these pipes have been in the ground since Victorian times, and even though they serve us really well, they still sometimes burst.

As the weather gets colder the amount of burst pipes increases, you can see why this happens in the film below. You can also report a burst or leak, or find out if we already know about it here.
