Backflow Prevention

We understand the importance of protecting your water supply from contamination and pollution. Our team of licensed plumbers specialises in backflow prevention, ensuring your drinking water remains safe and compliant with Australian regulations.

Backflow occurs when water flows in the opposite direction through your plumbing system, potentially allowing contaminants to enter the main water supply. This can happen due to pressure changes in the system, such as during a water main break or when high water demand causes a drop in pressure. A backflow prevention device is critical in preventing this reverse flow and safeguarding your water supply.

Our skilled team can test, install, and maintain backflow preventers to ensure your system functions effectively. These devices maintain adequate pressure on the main water intake and prevent any backflow into the water supply network, keeping your drinking water safe.

 Trustindex verifies that the original source of the review is Google. I can’t recommend CGC Plumbing (Corey and Tim) highly enough. I’ve been relying on them ever since I moved into my property, and they’ve been consistently reliable and professional every single time. The very first time I called them was during an emergency — I had a burst pipe, and Corey showed up quickly and had the issue sorted within an hour. That level of responsiveness immediately gave me confidence I was in good hands. More recently, they helped remove old ducting from my home’s crawl space and fixed a leak from my bathtub. Both jobs were handled efficiently and with great attention to detail. They always explain what needs to be done, show up when they say they will, and leave everything clean and tidy. It’s such a relief having plumbers you can genuinely trust. Corey and Tim do excellent work, and I wouldn’t hesitate to call them again or recommend them to anyone needing quality plumbing services.

 Trustindex verifies that the original source of the review is Google. Highly recommend Corey from CGC Plumbing Services. His technical knowledge, specialised plumbing equipment and patience to explain the works required was the reason why we used his services. The trade industry is full of untrustworthy individuals looking to rip you off, often leaving you with a large bill and damage that only has to be repaired again. We were very fortunate to have been referred to Corey to rectify shoddy and misdiagnosed work undertaken by previous plumbers. Don’t  waste your time not knowing who to use go with CGC plumbing.
