Your internal stop tap is usually found near to the point where your water supply pipe enters your home. Stop taps are most commonly found: under the kitchen sink, in a kitchen cupboard, in the bathroom, WC, cloakroom, garage/utility room, cellar or under the stairs. External stop taps form part of our water distribution system. If you can't find your external stop tap, give us a call on 0345 702 3797 and we check our mapping system and help you locate it. Some properties don't have external stop taps at all, if this is the case a qualified plumber will be able to carry out any necessary repair work by clamping or freezing your pipes.
