Installation, Testing & Repairs

Servicing Brisbane, Ipswich, Logan, Redlands & Redcliffe

O’Brien Electrical and Plumbing Coopers Plains are fully licensed and qualified to provide expert backflow prevention services for residential, commercial, and industrial properties. With over 35 years of experience in South East Queensland, we help protect your drinking water supply from contamination and ensure full compliance with council and Queensland Urban Utilities requirements.

Backflow prevention devices are essential for properties with potential cross-connections to the water supply, such as irrigation systems, commercial kitchens, and industrial facilities. Annual testing is mandatory for most devices, and we’re here to take care of it all—installation, certification, testing and repairs.

What is Backflow?

Backflow occurs when water flows in the reverse direction from a property’s plumbing system back into the mains water supply, potentially carrying contaminants such as chemicals, waste, or bacteria. This can happen due to sudden pressure changes in the system.

To prevent this, backflow prevention devices are installed on your water service. These devices must be tested annually by a licensed plumber endorsed for backflow prevention.

The after-hours plumbing service on Friday 3rd of July provided by Lachlan was excellent. His work provided a solution to the problem and allowed time for a more permanent solution to be undertaken.

Excellent service. I have had them look at and fix my roof a number of times. They are efficient, punctual and professional. The recent experience was to locate and fix where my roof might be leaking in various places. My roof is high and vast and the task challenging. They quoted well and returned several times to further investigate and fix, without extra cost. They answered emails and phone calls on Sunday. David, In particular, was very helpful and accomodating. Highly recommend.

10/10 would recommend. Obie and Anthony attended and did a great job with installing my new air conditioner. Both very kind and professional. Scott the electrical manager helped answer all of my questions and the receptionist girls were lovely on the phone and very helpful.
I will definitely be getting O’Brien out again.
