Turning off the mains water supply is an essential skill for homeowners and can be crucial in emergency situations or when performing plumbing repairs. Here’s a general guide on how to turn off the mains water supply:
1. Locate the Main Water Shut-Off Valve:
The main water shut-off valve is usually located near the point where the water main enters your property. Common locations include:
- Basement: Look near the water meter or where the water line enters the house.
- Crawl Space: If your home has a crawl space, check there for the shut-off valve.
- Garage: In some homes, the valve may be located in the garage.
- Exterior Wall: It may also be located on an exterior wall of the house.
2. Types of Shut-Off Valves:
There are typically two types of main shut-off valves:
- Wheel-Type Valve: This valve has a round wheel that you turn clockwise to shut off the water. It’s commonly found in older homes.
- Handle-Type Valve: This valve has a lever or handle that you turn or rotate. Turn the handle clockwise to shut off the water. This type is more common in newer homes.
3. Shutting Off the Water:
a. For a Wheel-Type Valve: – Turn the wheel clockwise until it is fully closed.
b. For a Handle-Type Valve: – Turn the handle or lever clockwise until it stops.
4. Test the Water Supply:
After turning off the main water supply, it’s a good practice to test faucets and fixtures to ensure that the water is indeed turned off. This helps you confirm that you have successfully shut off the water.
5. Label the Valve:
Consider labelling the main shut-off valve so that you and others in your household can easily locate it in case of an emergency. This is especially helpful if you have guests or if someone else needs to turn the water back on.
Remember, in some cases, you may need a special tool, such as a water meter key, to turn off the water if the shut-off valve is located at the water meter. It’s a good idea to familiarise yourself with your specific plumbing system and, if necessary, consult a professional plumber for guidance.
