Backflow Testing and Prevention cost guides & tips

Answers to Your Common Questions

Can I test my own backflow preventer?

In most Australian states, only licensed plumbers with backflow accreditation are legally allowed to test backflow preventers. DIY testing isn’t recommended, as it requires specialised equipment and must comply with local water authority regulations.

How often should a backflow preventer be tested?

Backflow prevention devices should be tested annually as required by many local councils and water authorities across Australia. Regular testing ensures your water supply stays safe from contamination.

Do I need a backflow preventer on my water line?

You may need a backflow preventer if you have irrigation systems, pools, rainwater tanks connected to mains, or commercial equipment. A licensed plumber can assess your setup and advise on legal requirements in your area.

Is a backflow preventer expensive?

Backflow preventers typically cost between $150 and $500, depending on the type and size. Professional installation and yearly testing may add to the cost, but it's a small price for protecting your drinking water.

How do I know if my house has a backflow preventer?

A plumber can easily confirm this, but you may also spot one near your water meter or main plumbing line. It usually looks like a metal valve with test cocks and a serial number plate.
