We offer affordable pricing and speedy service to keep your plumbing systems running at their best. When plumbing problems like backflow occur, call us for assistance.

Repairs And Replacements

Damaged backflow prevention valves can be hazardous to your health, may reduce flow of water, and ultimately will cost you money in a new system, potable water distribution and further necessary water sources.

To minimise your liability, QLD Coastal Plumbing will attempt to restore and reconstruct every make and model using original vendor parts, except in the case when a full replacement is cheaper. If that is the case, we’ll install a new government-approved backflow prevention device and properly file it with the local authority.

Our certified plumbers are here to ensure your drinking water quality, water pressure, and other water services including backflow prevention is exceptional and suits your needs and requirements.

Annual Testing

Your backflow valve must be annually tested and filed with the local authority to reduce the risk of contamination or backflow.

Our qualified backflow technicians can schedule and conduct annual checks, in addition to completing all the necessary paperwork for you.

QLD Coastal Plumbing Maintenance


Backflow prevention is one of the steps you can take to ensure the quality and safety of your home’s water supply. Backflow occurs when contaminated water reaches your pipes.

At QLD Coastal Plumbing, we include annual testing and servicing as well as backflow device repairs in case of emergencies.

We are here to make sure that your backflow protection system is operational and your water delivery is protected. Our professionals ensure that your water distribution systems are working effectively, thus preventing hazards like backflow from occurring in the future.
