Register with your supplier if you consider yourself to be vulnerable.

Prepare by keeping a supply of water that will meet your family’s needs, including your pets.

Check if your neighbours have lost services. If others are affected this will make a difference to what you should do.

Contact your water supplier to report the problem and ask for information.

Turn off all the taps and any central heating or electric immersion heaters.

Do not use your washing machine or your dishwasher.

Do not flush the toilet.

Use your supply of drinking water until the water is back on.

Be on alert for bogus callers posing as utility company workers. Always ask to see a Company Identification Card.

If it is a local issue, watch the local news and tune into BBC Radio Merseyside online for advice.

Contact your supplier for advice if your neighbours water supply has returned and you are still having problems.

Turn your taps on and let the water run until it is running clear.

Replace any supplies of water that have been used.
