FAQs
What is backflow and why is prevention important for commercial properties in Newcomb?
Backflow is the unwanted reversal of water flow in a plumbing system, which can allow contaminants such as chemicals, bacteria, or industrial waste to enter the public drinking-water supply. Commercial sites in Newcomb—restaurants, factories, medical centres, and apartment blocks—often have complex plumbing that connects to equipment like boilers, fire-sprinkler systems, and chemical wash stations. Without a properly installed and maintained backflow prevention device, these cross-connections pose a significant health risk to staff, customers, and the wider community. Backflow prevention protects your business from legal liability, avoids costly shutdowns by the water authority, and safeguards Newcomb’s potable water network.
What types of backflow prevention devices are commonly required in commercial buildings?
The correct device depends on the hazard rating of your site, but the most common units we install and service in Newcomb are: • Atmospheric Vacuum Breaker (AVB) – used for low-hazard outlets such as irrigation systems. • Double Check Valve Assembly (DCVA) – suitable for medium-hazard applications like apartment blocks or light commercial premises. • Reduced Pressure Zone Device (RPZD) – mandated for high-hazard environments such as chemical plants, commercial laundries, hospitals, and food-processing facilities. • Break Tank & Pump Sets – used where a physical air gap is required, often on processes with highly contaminated liquids. Your licensed plumber will assess your risk category and specify the compliant device in accordance with AS/NZS 3500 and Victorian Building Authority (VBA) guidelines.
How often does my business need to have backflow devices tested and certified?
Under the VBA Plumbing Regulations and Barwon Water trade waste rules, every testable backflow prevention device on a commercial property must be inspected and certified annually by a licensed Backflow Prevention Specialist. The technician completes a performance test using calibrated gauges, records the results on the official test report, and submits the certificate to Barwon Water within 10 business days. Failing to keep current certification can lead to fines, disconnection of water services, or even closure notices.
What signs indicate that my backflow prevention device may need repair or replacement?
Common warning signs include: • Continuous discharge of water from the relief valve on an RPZD. • Sudden drop in downstream water pressure. • Visible leaks, corrosion, or cracked housings. • Unusual tastes, odours, or discoloured water at outlets. • A failed annual test. If you notice any of these issues, isolate the device if safe to do so and call a licensed plumber immediately. Prompt repairs prevent contamination incidents and usually cost less than emergency replacements or regulatory penalties.
Are there local regulations in Newcomb that govern backflow prevention in commercial premises?
Yes. Commercial properties in Newcomb fall under: • Victorian Plumbing Regulations 2018 – require installation of backflow prevention appropriate to the hazard rating and annual testing of testable devices. • AS/NZS 3500.1:2021 – details technical standards for cross-connection control. • Barwon Water’s Backflow Prevention Policy – mandates registration of each device and submission of yearly test reports. • City of Greater Geelong Council health bylaws – enforce safe water supply practices for food and healthcare businesses. Non-compliance can result in infringement notices, suspension of trade-waste permits, or shutdown orders.
What is involved in a professional backflow prevention service visit and how can I prepare my site?
A standard service visit includes: 1. Site assessment and device location check. 2. Isolation of upstream and downstream valves. 3. Performance testing with calibrated differential gauges (for DCVA/RPZD). 4. Cleaning or replacement of internal seals, springs, and check valves if necessary. 5. Recording results on an approved test sheet. 6. Submission of certification to Barwon Water and issuance of a copy for your records. To prepare: • Ensure clear access to the backflow device (no locked cages or stacked materials). • Provide any prior test reports for reference. • Advise staff of a brief water shutdown (usually 15–30 minutes per device). • If the device protects critical equipment, plan for downtime or arrange a temporary bypass with the plumber. Proper preparation streamlines the visit, minimises business disruption, and ensures your plumbing stays fully compliant.
