How It Works
Precise Testing Services
Backflow testing in Cessnock involves checking the operation of your prevention device using calibrated gauges to monitor pressure changes and valve function. This process is essential for commercial and certain residential properties with irrigation systems, fire hose reels, or tanks connected to town water.
The service begins with an on-site inspection and identification of the device type and location. From there, the plumber isolates the unit, performs pressure tests in stages, and records all required data to submit to the council. If the device is faulty or non-compliant, you’ll be informed of your repair or replacement options with clear explanations and no-pressure advice.
Subat Plumbing Services aims to keep this process straightforward and non-disruptive for Cessnock property owners. We work efficiently to minimise downtime and take care of form submissions and due-date tracking. Our approach prioritises safe outcomes, responsible service and easy communication for all parties involved. When completed regularly, this service helps support long-term water system performance across homes and businesses in the region.
What is backflow and why is it dangerous?
Backflow occurs when water flows in the opposite direction through pipes, potentially allowing contaminants to enter the clean water supply. This can happen due to a drop in water pressure or a back siphon effect, such as when a hose or connected system sits below a contaminated source. If pesticides, chemicals, or wastewater are drawn into the system, it can pose health risks for anyone using that supply. This is why backflow prevention devices and regular testing are essential in many properties, especially those with irrigation, fire systems, or commercial plumbing connections.
Who needs backflow testing?
Backflow testing is required for any property that has a registered backflow prevention device. This commonly includes commercial properties, apartment complexes, schools, healthcare centres and some residential homes with irrigation or rainwater tanks connected to mains. Local councils and water authorities typically maintain a register of properties that require testing, and it's the owner's responsibility to ensure tests are carried out annually by a licensed plumber. Failing to meet this requirement can lead to penalties or water supply issues.
How often does backflow testing need to be done?
In most areas of Australia, backflow prevention devices must be tested every 12 months by a licensed plumber accredited in backflow testing. This schedule is set by local councils or water providers and is legally enforced. A reminder is typically sent by the authority, but it’s up to the property owner to arrange the test and ensure documentation is submitted. Some commercial settings with higher risk may require more frequent checks depending on the system and classification.
