Backflow Prevention Devices and Inspections

Backflow is the reversal flow of water in your pipes. If Power and Water’s water supply system drops pressure it can cause the flows direction to change and become contaminated.

A severe blackflow incident can put you and your families health, and lives, at risk.

Backflow Testing and Services

Tap & Drain Doctor NT are backflow accredited plumbers and can assess your property to define the hazard level. Our devices are tested and maintained annually to ensure that there will no contamination.

There are a number of approved devices available, including:

  • A break tank with a registered air gap
  • Reduced Pressure Zone Device (RPZD)
  • Double Check Valve (DCV)
  • Dual Check Valve (DuCV)

We will perform all works start to finish and provide documentation directly to power and water. If works do not pass, we will provide a hazard test report and quote on further repairs.

What Can Cause a Blockflow of Water:

Above ground water pipe

❌ A water supply systems pressure dropping due to a break.
❌ An excess of water pumped from the water main causing the pressure to drop.
❌ A connected pump that causes a reverse flow.
