Installation, Testing & Repairs

Servicing Brisbane, Ipswich, Logan, & Redlands

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

Backflow prevention devices are essential where there is a risk of cross-connection to the water supply—such as irrigation systems, commercial kitchens, and industrial facilities. These devices must be properly installed, maintained, and tested to remain compliant.

Our team manages the entire process, including installation, annual testing, certification, maintenance, and repairs—giving you peace of mind that your system is safe and compliant at all times.

What is Backflow?

Backflow occurs when water flows in the reverse direction from a property’s plumbing system back into the mains water supply. This can potentially carry contaminants such as chemicals, waste, or bacteria, posing a risk to public health.

Backflow is typically caused by sudden changes in water pressure, such as a drop in mains pressure or increased demand on the system.

To prevent this, backflow prevention devices are installed on your water supply. These devices are designed to stop contaminated water from entering the mains and must be tested annually by a licensed plumber endorsed in backflow prevention to ensure they remain compliant and functioning correctly.

Big thanks to the guys (led by Eric) who came out to my place! They didn't just rush through the job—they stayed a bit longer to make sure everything was actually sorted and even cleaned up after themselves. It’s a huge relief to have it done properly. Really appreciate the extra effort, guys!"
