Plumbing and maintenance

Finding and testing your stopcock before you need it

The single most useful five minutes in home maintenance is finding the internal stopcock and checking it actually turns.

Common questions

What if it will not turn?

Do not force it. A seized stopcock should be replaced under controlled conditions rather than during a leak.

Is there an outside one too?

Usually, at the boundary. It needs a key and is worth locating in advance.

What to check

Point 1

Internal stopcocks are usually under the kitchen sink, in a downstairs cloakroom or near where the supply enters the house.

Point 2

Stopcocks seize when never used; turning them fully off and on once or twice a year keeps them workable, and reveals a failing one before an emergency does.

Working out what is realistic in your space?

Room dimensions, the position of the window and where the waste leaves the building decide most of it. Send those and we can be specific.
