Backflow prevention in Capalaba and Brisbane

Backflow is when water flows the wrong way in a pipe and dirty water enters the clean supply. A backflow prevention device is a one-way barrier that stops it. They are common on commercial sites, irrigation systems, fire services and some homes.

Plumbing in a Hari holds a QBCC Plumbing and Drainage licence with a Backflow Prevention endorsement, so we can install, test and repair these devices. We check that the device suits the site, is fitted correctly and works as it should. If an existing device has failed or leaks, we can repair or replace it and explain what we found.

If you manage a property, or have been told you need a backflow device or a test, ring 0414 564 007. Send the address and a photo of the device if there is one, and we can tell you what is involved.

Yes. Plumbing in a Hari holds a QBCC Plumbing and Drainage licence with a Backflow Prevention endorsement, so we can install, test and repair backflow devices for homes and commercial sites. The licence and the Master Plumbers Association membership are shown in the licences section on the home page.
