Regular reporting of maintenance of your backflow prevention device is required by local governments in Queensland to ensure compliance. At S&J Plumbing and Gasfitting, we supply, install, maintain and test backflow prevention devices. There are testable and non-testable backflow prevention devices and which one is fitted to your network will depend on the contamination risk level of your property. If your property requires or already has a backflow prevention device, get in touch with us today.
What is Backflow and How Does it Occur?
Mains water is designed to be supplied under pressure to a property. Backflow occurs when water flows from a property’s mains plumbing network flows back into the mains supply and potentially poisons the water supply for other users. A backflow prevention device is a one-way valve that prevents water from re-entering the mains water supply once it has entered a property’s plumbing network. This can occur in one of two ways:
- Back siphonage – occurs when the pressure in the mains supply drops due to a leak or a draw that significantly reduces the flow of water, such as a fire hydrant being used upstream.
- Backpressure – this occurs when the pressure within a property’s plumbing network exceeds the pressure of the water supply.
- an irrigation system
- fire hose reels or fire hydrants
- commercial or industrial equipment or activities that could pollute the drinking water supply (air conditioning cooling towers, chemical cleaning areas etc.)
- water outlets in proximity to pollutants, grease traps or chemicals
- an alternate water supply
Without a backflow prevention device, there is a risk of chemicals, sewerage or other foreign contaminants entering the water supply.
We provide regulation testing along with a report that is suitable for providing to your local council. For example, in Brisbane, the Brisbane City Council requires all backflow prevention devices that are testable to be checked annually.

"I needed a plumber on short notice on the weekend. James arrived quickly and detected the problem and addressed it in a very professional manner. he was very focused in his work and the result was outstanding. Thank you James."
"These guys were prompt when we called them with no hot water and a blocked drain. They were reliable, honest and took pride in their business. I called 5 local plumbers and they were the only ones who picked up and then made space for us as we needed urgent help. And in the following days, only one of the other plumbers called back. I was very impressed with their work and will definitely be going back to them with any future plumbing needs. Thank you for everything!"
