Backflow Testing

Backflow prevention testing service

Have you received a notice from the council to test your backflow prevention device? Our expert backflow testers can complete the backflow testing and submit the report to the local council on your behalf.

Backflow prevention devices require annual inspection. Any fault in the rpz or dc valve can reduce the water pressure flow, and pollute the drinking water which can result in being penalised by your local council. Get your backflow prevention devices tested by Ryan Old Plumbings fully qualified and endorsed backflow plumbers. Book our expert backflow testers now.


What are Backflow Prevention Devices?

Backflow devices prevent harmful contaminants from entering the city’s main water supply. If back-siphonage or back-pressure occurs, it can pollute the potable drinking water and cause local residents to fall sick.

Double check backflow device (DC) and Reduced Pressure Zone Backflow device (RPZ) are commonly used to prevent backflow. At Ryan Old Plumbing, we install, test and maintain DC valves and RPZ backflow preventers. RPZ valves are installed in high-risk areas whereas DC backflow preventers are installed in low-risk areas. Your backflow prevention device will be installed in accordance with the hazard rating of the property.

  • Irrigation system connected to mains water supply
