Individual approved RPZ Valve Testers will not be Approved Contractors as defined in the Water Fittings Regulations.
In regards, to notification or other work associated with installing or replacing RPZ valves, these activities are outside the scope of the approved RPZ Valve Tester sector.
When installing or replacing RPZ valves every installer must meet the requirements as set out in the AIM and the Regulations. Where installers are separately approved as an Approved Contractor, they must meet their scheme’s requirements.
