Backflow Prevention

Protecting Sydney’s water supply, one property at a time.

Expert Backflow Prevention in Sydney

Is your backflow prevention device due for its annual test? Building a new property with an irrigation or fire system that needs one installed? Whatever the case, let Flusso Plumbing be your trusted partner for backflow prevention across Sydney.

We specialise in installing, testing, and maintaining backflow prevention devices for residential, commercial, and strata properties, keeping your water supply protected and your site fully compliant.

What is Backflow Prevention?

Backflow happens when water flows in the wrong direction through your plumbing system, potentially pulling contaminated water back into the clean water supply. It’s a bigger risk than most people realise, particularly on properties with irrigation systems, chemical use, or commercial processes connected to the mains.

A backflow prevention device stops this from happening, and depending on your property’s hazard rating, regular testing is required under local water authority regulations to keep it working correctly. Combined with our leak detection services, we help make sure your water supply stays clean and your plumbing stays compliant.

OUR BACKFLOW PREVENTION SERVICES

At Flusso Plumbing, we offer a complete range of backflow prevention services, from first installation through to ongoing compliance testing.

  • Backflow Preventer Installation
    We install the right device for your property, whether that’s an RPZ valve, a double check valve, or another assembly, sized and positioned correctly to meet compliance requirements from day one.
  • Backflow Prevention Device Testing
    Our certified technicians carry out annual compliance testing in line with AS/NZS 3500.1 and local water authority requirements, with results reported promptly to the relevant authority on your behalf.
  • Backflow Preventer Assembly Repairs & Maintenance
    If testing identifies a worn or faulty assembly, we repair or replace it quickly, keeping your property compliant without unnecessary downtime.

When You Might Need Backflow Prevention

A cross-connection in your plumbing system can put your water supply at risk in a number of situations, including:

  • New construction or renovation involving an irrigation or fire system
  • Commercial kitchens, medical facilities, or industrial sites using chemicals
  • Annual compliance testing that’s due or overdue
  • Strata or commercial buildings with existing backflow devices
  • A cross-connection flagged during a routine plumbing inspection


If you’re not sure whether your property needs a backflow prevention device, or it’s simply been a while since your last test, it’s worth getting in touch before it becomes a compliance issue.

Backflow Prevention for Every Property

Backflow prevention applies across a wide range of properties, from residential homes with irrigation systems through to commercial buildings, strata complexes, and construction sites.
