All plumbing systems have a backflow device known as an RPZ [Reduced Pressure Zone] Valve, which protects your water supply from contaminants and pollutants.

On installation, the RPZ Valve must be tested and certified to confirm protection against back pressure of contaminated water and thereafter should be re-tested annually to ensure it is still in full working order and no-one is at risk from consuming poor-quality water.

Only licensed professionals can test the operation of RPZ Valves, which is where the team at Enviroliance can help.

As industry leading specialists in water systems management and mechanical engineering, Enviroliance engineers boast extensive experience in working with commercial organisations to ensure their plumbing systems are up to par and that their water quality meets the required standards for safe public consumption.

A key part of this process includes the initial installation and certification of RPZ Valves, together with annual re-testing, where the latter can be completed in as little as half an hour.

Enviroliance work hard to establish long-term relationships with our clients and would welcome the opportunity to discuss the monitoring and maintenance of your water systems, which includes servicing and testing of RPZ Valves.
