Protect Your Water Supply with Professional Backflow Testing

Backflow prevention devices play an important role in protecting drinking water supplies from contamination. Regular backflow device testing ensures your prevention device is operating correctly and continues to provide the protection it was designed for.

At Hydro-Jett Plumbing, our experienced plumbers provide professional backflow prevention testing, servicing and repairs for commercial, industrial, residential and body corporate properties across Melbourne and the Eastern Suburbs.

Why Do You Need Backflow Testing?

Backflow prevention devices contain valves, seals and mechanical components that can deteriorate over time. Impurities in the water supply, general wear and tear, pressure changes and ageing components can all affect the performance of a device.

The seals within backflow prevention devices must remain watertight and capable of withstanding pressures of up to 1500 kPa. Many devices also contain spring mechanisms that can lose tension over time. If the spring mechanism fails to operate correctly, the valve may not function as intended, potentially defeating the purpose of the backflow prevention device.

Regular testing helps identify these issues before they become a compliance or water contamination risk.

Professional Backflow Prevention Testing

Backflow prevention devices require specialist knowledge, calibrated testing equipment and experience to test accurately.

Our qualified backflow plumbers have the expertise and equipment required to:

• Test backflow prevention devices

• Check valve operation and performance

• Identify worn or faulty components

• Check seals and pressure performance

• Service and repair backflow devices where required

• Provide testing documentation and reports

• Assist with ongoing backflow compliance requirements

We also maintain current knowledge of backflow prevention equipment by liaising directly with device manufacturers and keeping up to date with equipment requirements and testing procedures.

Annual Backflow Device Testing Requirements

Under AS/NZS 3500.1, backflow prevention devices are required to be tested by a qualified backflow plumber at least annually, with no more than 12 months between tests.

Following testing, reports are submitted to the relevant authorities where required as part of the property's backflow compliance obligations.

Backflow testing equipment must also be calibrated annually to help ensure accurate and consistent test results.

Keeping your backflow device testing up to date can help you maintain compliance, identify potential faults early and ensure your backflow prevention system continues to protect the water supply.
