RPZ Valve Testing and Installation

What is RPZ valve testing and installation?

An RPZ (Reduced Pressure Zone) valve is a type of backflow protection device. Backflow of water poses one of the biggest risks of contamination to the mains water supply. Backflow happens when there is a reduction of pressure, sucking contaminated water back into the drinking water supply. RPZ valve installation prevents this from happening.

RPZ valve meaning

RPZ stands for Reduced Pressure Zone and an RPZ value is a cost-effective device that prevents the backflow caused by reduced pressure.

Who needs to use RPZ valves?

RPZ valves are suitable for fluid category 4 risks which typically include the following:

  • Swimming pools
  • Launderettes
  • Food processing plants
  • Premises with significant dishwashing facilities such as restaurants, hotels, and bars
  • Car washing facilities

Organisations in the leisure and hotel sectors are particularly at risk.
