Under the kitchen sink

In most Irish houses the internal stopcock is in the cupboard under the kitchen sink, where the mains enters the house.

In most Irish homes the stopcock is on the pipe coming up through the floor under the kitchen sink.

Other places to check

Under the stairs, in a utility room, in the hot press or, in apartments, in a riser cupboard in the hall.

The outside shut-off

There's also a shut-off in the water meter box set into the footpath outside. It needs a long key, which most plumbers carry.

If it's stuck

Don't force it with pliers, because old stopcocks can snap. Ring us and we'll replace it with a modern lever valve so it's easy to turn next time.
