How can you install a RPZ Backflow Preventer?
Nu-Trend is a qualified Plumber and licensed Backflow Technician that can help commercial property owners ensure their kitchen, restaurant or cafe are compliant with current regulations.
We were called to a site because the owner of the restaurant received a letter from Sydney Water to install a Backflow Test Device for the property. It is compulsory for a restaurant, laundromat or hospital to have this device installed. These type of commercial working areas are classified as high hazard which requires a high hazard Backflow device such as an RPZD needs to be installed.
This valve protects the Sydney Water mains from any back charge that may occur in the line in the rare case of disinfectants, cleaners, oils or grease are syphoned from the property, kitchen or grease trap areas during cleaning or maintenance.
The valve has two testable check valves, which close when they sense a Backflow in water pressure. It also has a vent on the bottom which expels any residual water in the valve when this occurs, meaning the valve is more suitable outside, but can be installed indoors with a tub dish drain beneath the vent.
On inspection of this property we found one valve needed to be installed on the main water meter. Another two valves needed to be installed on the two hose taps closest to the grease trap, as these taps would be considered high hazard because they could be used for cleaning during maintenance of the grease trap.
The valves will need to be tested annually to ensure the check valves and vent are in working order.
The type of backflow prevention device you require will depend on your site
The hazard rating of your site’s processes will determine which type of device you need to install. If the hazard rating varies due to multiple processes, you must apply the highest hazard rating.
Reduced pressure zone device (hazard rating – high)
This device has two independent action, non-return valves that are force-loaded to the closed position. A relief valve is positioned between the non-return valves and is arranged to be force-loaded to open to the atmosphere.
Break tank/air gap (hazard rating – high)
This device has an air break (physical gap) between the lowest water service pipe outlet and any upstream tank, fitting or container.
Testable double check valve (hazard rating – medium)
This device has two independent action, non-return valves that are force-loaded to the closed position. It is fitted with three test taps for yearly testing.
