RPZ FAQs: Notification

When do I notify the installation or relocation of an RPZ valve?

Details of the proposed work/installation shall be sent to the relevant water undertaker no less than 10 working days before work is due to start. Installing or using RPZ valves without the required consent could result in enforcement action being taken by the water undertaker.

Please note that failure to provide the minimum level of information required may delay consent. Contact the local water undertaker for further information.
