Not Having Adequate Protection Can Be Catastrophic!

Preventative Maintenance for your Backflow Valves

A backflow prevention device is used to protect water supplies from contamination or pollution. Backflow is more likely to occur if there’s a drop in pressure in the main or water pressure at the property is higher than at the main.  Back flow prevention is an essential service and the results of not having adequate protection can be catastrophic.


As a property owner, the last thing you want is to be caught out with a major plumbing disaster. It is the owners responsibility to arrange a qualified person to conduct ongoing annual servicing, testing and lodgement of test results forms for testable devices with the relevant Network Utility Operator. We can schedule a backflow valve preventive maintenance program that will suit your needs.
