Approved catering installers have passed an assessment certifying their ability to install commercial catering equipment, such as vegetable cleaners and dishwashers.
These contractors are certified to install cold water chillers or water coolers connected directly to the mains, in compliance with the Water Fittings Regulations and Byelaws.
Reduced Pressure Zone Testers are trained and authorised to test Reduced Pressure Zone valves, otherwise known as RPZ valves or Type BA backflow protection devices.
These devices stop water flowing in the wrong direction.
By law, these devices must be tested at least once a year to ensure they are working properly to protect the water supply.
The installation, commissioning, and testing of RPZ valves should only be carried out by accredited and approved testers, in accordance with the Water Suppliers’ Approved Installation Method AIM-08-01.
