Backflow Prevention Georges River
Need help with backflow prevention? EKORP services Georges River. Call to discuss the property, the work and current availability.
Where’s the job?
Backflow prevention in the Georges River area has a particular flavour: the mix of Federation and post-war homes across postcodes 2207 to 2223 means plenty of properties still carry ageing brass valves on garden tap and irrigation lines that have never been assessed.
Requirements can vary by property and authority. We will help you confirm what applies before work begins.
Backflow risks in older Georges River homes
Older galvanised and copper supply lines combined with mains-connected garden taps and irrigation are the classic Georges River backflow pathway. Add mature gardens in Oatley and Lugarno running irrigation off the mains, and plenty of properties carry more risk than their owners realise.
A pressure event on the network is all it takes. Sydney Water maintenance around Riverwood regularly drops mains pressure, and without a working device an irrigation line sitting in soil becomes a contamination pathway back to the tap.

- Older galvanised and copper supply pipework
- Mains-connected irrigation on Federation blocks in Oatley and Lugarno
- Shared backflow assemblies on Hurstville and Kogarah strata
Testing and certification across the council area
Annual testing runs the same everywhere: operational test, differential pressure measurement, valve and seal checks, and a same-day Sydney Water certificate. We cover Hurstville, Kogarah, Allawah, Carlton, Penshurst, Mortdale, Oatley, Riverwood, Lugarno, Beverly Hills and Peakhurst.
Urgent jobs, a failed RPZD or a compliance notice with a deadline, get prompt service. Call early and we aim for a morning slot.
Strata blocks and commercial premises
The containment device on a strata connection is almost always common property, which puts testing squarely with the owners corporation. We manage annual programs for Hurstville and Kogarah strata blocks, lodge the reports and keep the paperwork straight so the committee has one less thing to chase.
Commercial premises with trade waste, kitchens or cooling systems carry higher hazard ratings and usually need a double check valve or RPZ valve on the service connection, tested every year.
Installs and repairs done in one visit
A standard residential installation takes between one and three hours depending on the device and where it sits relative to the meter. Older homes in Hurstville, Oatley and Mortdale occasionally take a little longer when the original supply pipework needs attention. Vans stock parts for the common device types, so most failed devices are repaired and re-tested the same visit.

Questions
Common questions about backflow prevention.
Here are clear answers to common questions. Call us if you need help with something else.
How do I know if my property requires backflow prevention devices?
Properties that require backflow prevention include those with in-ground irrigation systems connected to mains water, fire sprinkler or hose reel systems, swimming pools with mains top-up connections, commercial equipment such as dishwashers or cooling towers, and any connection involving chemicals or non-potable water. If you are unsure, we can conduct a risk assessment to determine exactly what your property needs. Sydney Water may also have placed a requirement notice on the property title if a backflow device was required at a previous stage.
What are the different types of backflow prevention devices and which one do I need?
The main types are Reduced Pressure Zone Devices (RPZD), Double Check Valve Assemblies (DCVA or DCV), Pressure Vacuum Breakers (PVB), Atmospheric Vacuum Breakers (AVB) and Dual Check Valves. The right device depends on the hazard rating of your connection. High-hazard connections such as chemical systems require an RPZD. Medium-hazard connections such as irrigation systems on commercial properties typically require a DCV. Low-hazard connections may be served by a dual check valve or vacuum breaker. Our plumbers assess the hazard level on site and specify the correct device class.
How long does backflow prevention device installation take?
A standard residential backflow device installation takes between one and three hours depending on the device type and where it needs to be installed relative to your water meter and existing pipework. Commercial and industrial installations can take longer, especially where new pipe runs are required or the device needs to be installed in a confined space. We provide a time estimate as part of the quote so you know how long your water supply will be off during the installation.
Who is responsible for backflow testing in a strata building?
The containment device sits on the property's connection to the Sydney Water main, which is almost always common property, so the owners corporation is normally responsible for testing it. Individual lot owners are not usually billed directly. Check the strata plan and the Common Property Memorandum if the boundary is disputed.
