RPZD & backflow Testing

Backflow testing is imperative to ensure the prevention of water contamination.

This process is vital for protecting bathing and drinking water, and making sure it safe for human use.

Backflow can be prevented by the installation of an averting-valve, a one-way device that stops the backwards movement of water through pipes. These devices require regular maintenance to ensure they are operating correctly and their effectiveness has not deteriorated due to age or wear.

On all Commercial and industrial properties, that have Restricted Pressure Zone Device (RPZD) system installed, the Water Corporation require testing be carried out annually on the system by an accredited Backflow Testing agent, using a calibrated testing device.

Mackie Plumbing and Gas test and repair all backflow prevention devices, sized from 20mm to 300mm.

We also install RPZD devices on new builds and properties as required.
