Assuming the worst has happened, the first thing you should do is turn off all water at the stop tap (sometimes called stop cocks or stop valves).
The stop tap controls the water entering your home and is often sited under the kitchen sink, but it depends on where the service point enters the property. Sometimes you will have an additional stop valve in your loft or airing cupboard.
A good tip is to find these stop valves and label them before any plumbing emergencies occur. Try to gently turn them off and back on again. If it won’t budge, don’t force it - you’ll need to get a plumber to replace it.Watch our film on how to find and turn off your stop tap.
The next thing you should do is open all cold water taps so the pipework and storage system drains quickly, this will help to reduce the damage. Do not turn on hot taps. Turn off the central heating system and, if it uses a solid fuel boiler, allow the fire to die out. Switch off any electric immersion heater, and then call a WaterSafe plumber.
