Backflow Testing

Backflow testing, commonly known as RPZ testing is an annual test to ensure that all backflow prevention devices are working correctly on a property. Backflow occurs when the normal direction of water flow in your plumbing is reversed. In addition, backflow is a hazardous when your water supply is inadvertently interconnected to a source pollution. Moreover, as a building or property manager, backflow testing is important to ensure your backflow devices are working correctly.

Albeit, backflow issues do not occur regularly because of the regular testing. Backflow only occurs when the water delivery main is at a lower pressure than your plumbing system. For example, a burst or ruptured mains can cause a Backflow problem. As well as excessive demand during firefighting operations. It can also occur if a pump is connected to your water plumbing system.

Each backflow prevention containment device must be tested on an annual basis as a condition of connection to the water supply. As a result of regular professional testing, the backflow device will operate effectively. Backflow testing ensures the drinking water supply is safe from backflow.

If a device is defective or faulty, it may:

  • Not prevent a contaminated source entering the drinking the water supply
  • Cause water to be wasted through leaking devices
  • Impact on water pressure supplying the property
