Backflow Prevention Systems
Backflow prevention is essential for safeguarding our drinking water. In commercial and multi-residential properties, backflow prevention systems stop contaminated water from flowing backward into the mains supply – a vital protection for public health. MPJ Plumbing Group offers professional backflow prevention services across Sydney, ensuring your property’s backflow devices are properly installed, regularly tested, and fully compliant with local regulations. Whether you need a new backflow preventer fitted on your incoming water line or an annual test of existing valves, our accredited plumbers are here to help. We work with all types of backflow prevention devices (such as RPZ valves, double check valves, and vacuum breakers) and ensure they perform flawlessly so you, your occupants, and the wider community can trust the water coming from every tap.
Our Backflow Services
Installation & Replacement
Annual Testing & Certification
Sydney Water and local councils require testable backflow devices to be certified annually by accredited plumbers. MPJ Plumbing Group’s team includes backflow-accredited specialists who will perform your annual test. We use calibrated equipment to check that the valve is preventing backflow as it should – ensuring the check valves hold pressure and the relief valve (for RPZ) opens at the correct point. After testing, we provide you with a detailed report and a compliance certificate. We can also submit the necessary paperwork to Sydney Water on your behalf, so your records stay up to date.
Maintenance & Repairs
Backflow devices have internal seals and springs that can wear out or get fouled by debris. If our testing uncovers any issue (for example, a valve that’s leaking or not sealing properly), we can often repair it immediately by cleaning the device or replacing parts like rubber seals, seats, or springs. We carry common repair kits for major brands to get things fixed on the spot. Regular maintenance, like cleaning out strainers and exercising valves, is also part of our service to prolong the life of your backflow preventer.
Site Assessment
Not sure if your building has the required backflow protection? We offer site assessments where we review your plumbing setup and identify any cross-connection hazards. We’ll advise if and where backflow preventers are needed according to regulations (for instance, on your main water meter, on fire services, or on specific equipment like chemical cleaning outlets). This is especially useful for older properties or when undergoing renovations or new compliance checks.
