My mains water stopcock is not under my sink. Where can I find it?

All modern homes are fitted with both inside and outside mains water stopcocks, so don’t worry if yours isn’t under the kitchen sink.

Here are some common places to check inside your property:

  • In an airing cupboard

  • Under the bathroom sink

  • Inside a utility cupboard

  • Under floorboards near the front door

  • In a garage or cellar

  • Behind a panel near the boiler

If you live in an apartment building, the mains water stopcock might be shared between homes. If you're not sure where yours is, it’s worth checking with your neighbours, they might be able to help you find it!
