RPZ Valve Testing

What’s the Issue?

How do I recognise if I have an RPZ valve on my premises that requires regular testing?

How can I arrange annual certification of my RPZ valve?

2

What is your obligation?

It is a legal requirement to have RPZ Valves checked on a regular basis, at least yearly, to ensure they provide the backflow protection required.

The Water Suppliers’ Approved Installation Method AIM-08-01 states that commissioning and testing of these types of valves can only be carried out by an accredited tester approved by the Water Supply Industry.

Risks

There have been numerous well documented cases where backflow has resulted in contamination incidents which were harmful to the health of others. It is a criminal offence to contaminate the water supply or to use fittings which cause or are likely to cause contamination. This applies equally to backflow causing contamination of water in the Water Supplier’s mains or in the customer’s premises before use.

By not undertaking regular testing of your RPZ valve you could leave yourself open to possible contamination of your water supply.

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.

The Water Suppliers’ Approved Installation Method AIM-08-01 states that commissioning and testing of these types of valves can only be carried out by an accredited tester approved by the Water Supply Industry.

RPZ Valves are used to protect water supplies from contamination or pollution. Each valve is required to have its own unique reference number for identification purposes and should be permanently attached or engraved on the body of the valve.

If an RPZ valve is part of an equipment, such as, a standpipe or cement-batching plant and is routinely moved around, then this valve must be tested on being transferred from one place to another or at intervals not exceeding six months, whichever occurs first.

In the event of an RPZ valve failing a test, it should be repaired or replaced and then re-tested until satisfactory. If this cannot be completed within a 72-hour period then the Water Supplier must be informed immediately. They will then assess the nature of the failure and decide whether it is appropriate to shut off the water supply or if other measures can be undertaken to minimise the risk.

On completion of a test, a ‘test report’ certificate must be completed by the tester in accordance with the requirements detailed within ‘The Water Suppliers’ Approved Installation Method AIM-08-01’. Copies must then be provided to the person responsible for the device and to the Water Supplier within 10 working days.
