What is an RPZ Valve & why do you need one?
An RPZ valve (also commonly known as an RPZ assembly) is a vital component in protecting water supplies from contamination caused by backflow. These valves are a legal requirement in commercial premises where there is a potential risk of polluted water entering the mains supply.
Businesses such as healthcare providers, manufacturing plants, food and beverage production sites, and commercial kitchens, as well as the education sector, are typically required to install and maintain RPZ valves under the Water Supply (Water Fittings) Regulations 1999.
