Ok don't panic we will help first pick up the phone and call us. We have put together a small guide to how you can shut down your problem before it spreads. We have talk you through by phone or you can simple local on the guide to where your emergency shut off valve may be.
Under the Sink
The first place to look for your Stop Valve, is just under the sink where you will find a brass looking Valve. Then you need to turn this clockwise to turn off. Sometimes the Stop Valve is found to be very stiff when turning off so you may need some grips to add extra pressure while turning off. A dry cloth can be a great idea.
Sometimes you may find the Stop Valve behind your washing machine, whether it is in the utility room or located in the kitchen.
In the living room, especially in some council houses, you may find your Stop Valve located either built in a box or on a wall fitting.
It's unusual to find the Stop Valve under the stairs, but in council houses this is a popular location when you have 2 cupboards where the Water Mains Pipe runs just below the concrete under the living room floor, then up through the cupboard.
Sometimes you will find the stop valve behind the toilet, especially when it comes to flats.
