How to turn off your water supply

1. Get your tools ready

Before you get started, make sure you've got:

• some protective glasses
• some rubber gloves
• some penetrating oil, such as WD40

2. Find your stopcock

The stopcock is the valve which lets you shut off the water supply to your home. You can usually find it under your kitchen sink, but it's sometimes found in a cupboard in the hallway instead.

3. Close the handle

You may find that the handle on the stopcock has seized up over time, especially if it hasn't been used in a while. If that's the case, you can spray it with some of the penetrating oil to help loosen it up. Once you've got it moving, turn the handle clockwise until it's fully closed to turn off the water supply.

4. Find your outside stopcock

If you need to turn off the water supply outside, just look for this square metal cover. It might be at the end of your drive, or it might be near the public pavement. Carefully prise the lid open with a screwdriver, and turn the handle inside clockwise until it's fully closed. If you've followed these steps, you should now know how to turn off your water supply.
