Where's my stop tap?

It’s important to know where your stop tap (sometimes called a stopcock or water mains tap) is, how to use it, and who to contact you when you have a problem. It lets you turn off your water in emergencies, and so plumbing work can be carried out in your home.

Stopcock, stop valve and stop tap

These names are used interchangeably. Learn where to find both your internal and external stop tap, when to use them and who to contact if there's an issue.

Internal stop tap

You’ll have an internal stop tap somewhere in your property. Your internal stop tap should be used as the main way to turn your water on and off. You'll need to use it if you have a leak or when carrying out plumbing or general renovations. 

Where to find your internal stop tap 

It's usually found under the kitchen sink, but you may also find it under the stairs or in the downstairs toilet. If you live in a flat, there may be a communal stop tap that supplies several flats. Or, you may have a stop tap in your flat where your water supply enters.

What if there’s a problem with my internal stop tap?

As it’s in your home, it’s your responsibility to install, maintain, fix and replace your internal stop tap. If it’s faulty or needs to be repaired, you will need to call a plumber to fix it.

Home renovations

We will not attend to faulty stop taps. If you are carrying out work on your home, you can use your internal stop tap to turn your water off. It if isn’t working, you'll need to call a plumber who can freeze a section of the internal pipe or fit an Aladdin valve to shut the water off.

External stop tap

Outside your property, you’ll also have an external stop tap which can be used to shut off the water in the event of an emergency. You shouldn't rely on it to turn the water off inside your home, you should use your internal stop tap for this. 

Where to find your external stop tap

External stop taps are normally found under a cover outside your home on a footpath, driveway, garden or grass verge. They control the cold-water supply going into your home. 

What if there’s a problem with my external stop tap?

We’re responsible for external stop taps. We’ll consider fixing or installing a new external stop tap if:
•    there's an urgent risk to health such as no water going in to your property
•    there's a confirmed serious leak. 

To make sure we invest in the areas that need it the most, we cannot attend if your stop tap is broken, to help locate your external stop tap, isolate the water supply or make a chamber accessible unless there is a leak which you're unable to isolate yourself. If your stop tap isn't working, the quickest way to turn your water off is to contact a plumber.

What to do if I have a leak? 

Higher than usual bills, low water pressure, or a damp patch may suggest you have a leak but there aren’t always obvious signs. To find out if you have a leak, you may need to do the water meter test. 

If you do have a leak:

  • turn off your water using your internal stop tap and open all taps to drain the water from your pipes
  • switch off any electrical items if the water is close by
  • use towels to soak up or block off any water
  • turn off your boiler if you have a burst pipe.

Contact an approved plumber as soon as possible. 

If the leak is outside your home or from your external stop tap, then turn the external stop tap off and report it to us
