RPZ FAQs: General

W​ho can install an RPZ valve?

There are no legal restrictions on who can install an RPZ valve. But anyone installing one should be competent to do so and the valve installed and tested in accordance with all the condition of consent which apply.

Water undertakers recommend a competent installer, such as an approved contractor, is engaged to undertake this work.

If there are any questions about the conditions of consent, contact the local water undertaker for further information.
