The company is advising customers to check and insulate water pipes in their homes and businesses ahead of the colder winter weather hitting.
Sub-zero temperatures can cause pipework to freeze and when the weather starts to warm again, it can put strain on the pipes causing them to crack, leak or burst.
United is promoting the acronym PIPE to help customers remember their advice: Prepare, Insulate, Protect, Easy.
This includes knowing the location of your stop tap, checking its functionality, insulating pipes in cold areas, and protecting exposed equipment like outside taps.
Pipes in garages, cellars, outside, and loft spaces are most at risk of freezing.
A spokesperson for United Utilities said: “There’s lots of fantastic advice and simple instructions on our website, which can really help avoid the heart-breaking and costly situation of dealing with burst pipes.”
