How do I turn off my water supply
Internal stop cocks can usually be found in the pipework under your kitchen sink or in the downstairs bathroom or cloakroom. They are sometimes located in basements.
External stop cocks are normally found in the footpath just outside your property. In some cases there will be only one stop cock serving a number of properties (a shared supply), so it may not be right outside your property.
External stop cocks are owned by Irish Water and should only be operated by people who are working on behalf of Irish Water, except in the case of an emergency and/or if everyone whose water supply is controlled by the stop cock has agreed to the supply being turned off.
Stop cocks usually have a plastic or metal cover marked "Water" or 'Uisce'. however. If you do have difficulty locating your stop cock please contact Irish Water at the details below.
