Backflow Prevention Device Testing

Butler Plumbing- Commercial Plumber in Melbourne

For commercial buildings and large domestic complexes backflow prevention is a crucial part of protecting drinking water. Annual inspection and testing of your backflow devices by an accredited backflow prevention plumber is compulsory.

What Is Backflow?

Backflow occurs when water flows in the wrong direction through your metre assembly. This can result in contaminated water syphoning backwards into the water mains and contaminating the public water supply.

The risks associated with contaminated water are real and can have very serious consequences. It can cause serious illness, injury claims, and open the building owners up to liability claims. Backflow prevention is a crucial part of protecting your drinking water and water supply systems.

Your Legal Obligations

Under regulation 12 of the Water (Estimation, Supply and Sewerage) Regulations 2014, as the Owner/Occupier of a property, you must ensure that the correct backflow device(s) have been installed and are inspected and tested by an accredited and licenced backflow plumber.

Backflow Testing Compliance Regulations (Australian/New Zealand Standard 3500, National Plumbing and Drainage regulations) require annual inspection and testing of Backflow Prevention Devices.

Butler Plumbing has certified backflow prevention plumbers who are licensed to undertake inspection, testing and repairs of your backflow prevention devices. We will provide an inspection report that can be forwarded to your Water Authority, ensuring compliance with the regulations.

Time To Get Your Building Compliance Requirements In Order

This requirement has been in place for some time, however, the level of compliance in the industry has not always been up to standard. From our experience in working in the Melbourne plumbing industry for over 30 years, we have observed many buildings where the current standards are not being met, such as:

  • An appropriate backflow device has been installed, but there is no documentation of annual testing
  • The wrong type of device has been installed for the type of risk profile of the building
  • No device has been fitted at all

COVID-19 has resulted in an increased focus on Public Health and Safety. Water Authorities are paying greater attention to public health issues including Backflow Testing Prevention. Those without appropriate devices or fail to meet their annual compliance requirements are facing penalties and the potential that the water authority could disconnect the water until the building is brought up to code.

I have been using Butler Plumbing for years now. It is always easy to contact them and their plumbers turn up when they are scheduled to arrive. Repairs are always done professionally, and communication is excellent.

It was all excellent, from the initial phone call to the service person who came and checked my gas water heater, discussed it with me and then replaced the heater. A very good efficient and pleasant experience.

I dealt with Steve and Aaron in the process of getting a new hot water system. They were prompt, reliable and knowledgeable. Aaron completed the installation, he was on time, tidy, and a really nice guy to deal with. He seemed very experienced, was thorough, and was happy to answer any questions I had.

I would recommend Butler Plumbing

I was lucky enough to have Keelar ,(hope I am spelling that right) fix my bathroom tap, a problem plaguing me for quite some time. He calmly resolved the issue and even cleaned up the excess mould. Highly recommend these guys!
