When a plumbing emergency happens, such as a burst pipe or an overflowing toilet, knowing how to shut off the water supply can be the difference between a manageable problem and serious water damage.
It is worth taking time to check where the main shut-off points are in your home before an emergency ever happens.
Start With Individual Fixtures
Many taps, toilets and appliances have their own local shut-off valves connected to the water supply pipes. These are often located directly under sinks, behind toilets or behind appliances like washing machines. In most cases, turning them clockwise will shut the water off to that individual fixture.
Find The Internal Stop-Cock
If you cannot locate a local valve, the next best option is the internal stop-cock for the house. This is often found where the cold water pipe enters the property, commonly in or near the kitchen. Turning it clockwise will usually shut off the water supply to the whole house.
Know The External Stop-Cock Too
There is often also an external stop-cock outside the property. This is generally for emergency use only and may affect neighbouring homes depending on the layout of the supply, so it should be approached with care.
Do Not Ignore Smaller Problems
Burst pipes and major water damage often begin with smaller issues that were overlooked. Small leaks, damaged pipework and repeated plumbing faults should be checked early before they become more serious.
Shutting off the water is an emergency response, not a fix. Once the supply is under control, it is best to have the problem checked properly by a registered plumber.
