Once you’ve located your stopcock, it’s a good idea to regularly test it to make sure it doesn’t get stuck in one position, and will always be ready to use in an emergency.
It is important to turn off your boiler before you shut off the water to your home, to reduce any chance that your boiler may attempt to run without an adequate water supply.
To turn off your internal stopcock:
- turn the top clockwise until you can feel resistance, the same as when you turn off a tap.
