RPZ Valve Tester

What are RPZs?

Type BA backflow protection devices are more commonly known as Reduced Pressure Zone valves or RPZ valves. It is a legal requirement to have these devices checked on a regular basis, at least yearly, to ensure they provide the backflow protection required.

All installations, commissioning and testing must be carried out in accordance with the Water Suppliers’ Approved Installation Method AIM-08-01. The commissioning and testing of these valves must only be carried out by an accredited tester approved by the local water supplier.

Note: The Water Suppliers' Approved Installation Method AIM 08-01 is currently under review.
