The installation and use of RPZ Valves must be notified in advance to the Water Supplier  and may be subject to additional terms and conditions made by the Water Supplier when granting consent. Potential users of RPZ Valves must be made aware of all the terms of consent regarding installation and maintenance. RPZ Valves create a pressure drop across the device and may not be suitable for use on low pressure supplies. The water pressure at the intended location of the valve must be known before it is installed and must be suitable.

If you need to have an RPZ Valve installed, or are unsure of the regulations, Bluewater Valves can advise and in most cases help to complete the required paperwork prior to installing and commissioning your RPZ Valve.

Our many year's experience will enable us to select the most appropriate valve arrangement for your particular application.

A full list of WRAS Approved products, including RPZ valves, can be found in the 'Water Fittings and Materials Directory', on the WRAS website www.wras.co.uk
