BACKFLOW TESTING SYDNEY - TESTING, REPAIRS & INSTALLATION

If your property is connected to Sydney Water’s network, your backflow prevention device is a legal requirement, and it needs regular backflow testing to prove it still works. GAP Trade Services provides accredited backflow testing, repairs and installation for homes, businesses and strata buildings across Sydney.

Backflow happens when water pressure drops and creates negative pressure in the pipes. Dirty water can then be drawn back into the clean drinking water supply from toilets, basins, sinks, swimming pools or the ground.

A working backflow prevention device stops that happening, protecting your building and the wider water supply.

Only certified plumbers with accreditation from a registered training organisation can test or work on backflow prevention devices. GAP Trade Services is fully accredited for this work, including reduced pressure zone devices (RPZDs).

Once your backflow test is done, we submit and certify the results through Sydney Water’s online lodgement system, so your compliance is on record and you don’t have to deal with the paperwork.

BACKFLOW TESTING

We test your backflow prevention device, including RPZDs, to confirm it’s working as it should. Testable devices must be checked at least once every 12 months to stay compliant.

SYDNEY WATER LODGEMENT

Once your backflow test is complete, we submit and certify the results through Sydney Water’s online system. You’ll receive a copy for your records, so there’s no paperwork for you to chase.

REPAIRS & SERVICING

If your device fails its test, we’ll explain why and quote the repair before we start. Once it’s fixed, we retest it and lodge the passing result with Sydney Water.

BACKFLOW DEVICE INSTALLATION

We supply and install new backflow prevention devices sized to suit your property’s hazard level. Every new device is tested after installation, and the results are lodged with Sydney Water.

BACKFLOW TESTING SYDNEY - APPLICATIONS

HOSPITALS, HEALTH AND COMMUNITY FACILITIES

Hospitals | Medical Centres | Dental Clinics | Vet Clinics | Aged Care | Schools | Childcare Centres

Protecting vulnerable people

Health and community buildings serve the people most at risk from contaminated water, such as patients, elderly residents and young children. That’s why these sites are usually given a high hazard rating, and why backflow testing is such an important part of keeping them compliant.

Equipment connected to the mains. Sterilisers, dialysis units, dental chairs and vet surgery equipment all draw from the water supply, and each one is a potential backflow point.
Higher consequences. A backflow event could expose patients, residents or children to bacteria, chemicals or bodily fluids.
RPZDs are common. Most hospitals and medical sites need a reduced pressure zone device, the highest level of backflow protection.
Annual testing required. Testable devices must be tested at least every 12 months, and after any repair or relocation.
Compliance on record. We lodge your results with Sydney Water, so your facility has the records it needs for audits and accreditation.

COMMERCIAL AND HOSPITALITY

Restaurants | Cafes | Commercial Kitchens | Hotels | Shopping Centres | Laundries | Hairdressers

Backflow prevention is essential in commercial kitchens

Keeping food, drink and customers safe

Commercial kitchens and service businesses use water in dozens of ways every day, and much of that equipment connects straight to the mains. Backflow testing protects your customers, your staff and your reputation.

Kitchen equipment. Coffee machines, dishwashers, glass washers and combi ovens can all allow backflow if pressure drops.
Post-mix drink systems. These need protection to stop carbonated water flowing back and reacting with copper pipework, which can contaminate drinks.
Laundries and salons. Washing machines and salon basins mix water with detergents, dyes and chemicals that must stay out of the drinking supply.
Stay compliant. Annual backflow testing keeps your business meeting Sydney Water’s requirements and avoids problems at inspection time.
Minimal disruption. Testing can be scheduled to suit your trading hours.

STRATA AND PROPERTY MANAGEMENT

Apartment Buildings | Strata Complexes | Office Buildings | Commercial Property | Homes with Pools, Irrigation or Rainwater Tanks

Staying compliant across your buildings

Managing backflow compliance across one or more buildings means keeping track of devices, due dates and reports. We take care of the testing and the paperwork, so strata managers, property managers and owners can tick it off the list.

Devices at the meter. Most multi-unit and commercial buildings have a testable backflow device at the water meter that must be tested every year.
Pools, irrigation and fire services. These often need their own backflow devices, each with its own testing requirements.
Hidden risks. Pool top-up lines can draw back chlorinated water, and irrigation can draw back fertilisers, pesticides and soil.
Testing and lodgement handled. We test each device, lodge the results with Sydney Water and let you know if anything needs attention.
Reports for your records. You’ll receive a copy of each test report for your building or strata records.

INDUSTRIAL AND FIRE SERVICES

Factories | Workshops | Laboratories | Car Washes | Fire Sprinkler Systems | Fire Hydrant Systems

Containing chemicals and process water

Industrial sites and fire services carry some of the highest backflow risks, because the water in these systems can contain chemicals, detergents or additives. Reliable backflow protection and regular testing keep that water where it belongs.

Chemicals stay contained. Chemicals, detergents and process water from factories, workshops, laboratories and car washes must never reach the mains.
High hazard sites. Most industrial sites are rated high hazard and need an RPZD, which must be tested at least every 12 months.
Fire service water. Water that sits still in sprinkler and hydrant systems can become stagnant or contain additives, so it must be kept separate from the drinking supply.
Testing alongside fire safety checks. Fire service backflow devices need regular testing, which can be planned around your annual fire safety inspections.
New and existing devices. We install, test and repair backflow prevention devices for new fit-outs, upgrades and existing systems.

FAQs - BACKFLOW TESTING SYDNEY

How often does backflow testing need to be done?

Testable backflow prevention devices, such as RPZDs and testable double check valves, must be tested at least once every 12 months. They also need testing straight after installation, repair or relocation. The results must then be lodged with Sydney Water.

Who can carry out backflow testing in Sydney?

Only a licensed plumber with backflow accreditation from a registered training organisation can test, repair or install backflow prevention devices. The plumber must also submit and certify the results through Sydney Water’s online lodgement system. GAP Trade Services is fully accredited and handles this for you.

What happens if my backflow device fails its test?

A failed test means the device may not be protecting the water supply, so it needs attention. We’ll explain why it failed and quote the repair before starting any work. Once the device is repaired and passes a retest, we lodge the result with Sydney Water.

Do I need backflow prevention at home?

Most homes are protected by the backflow device built into the water meter. Homes with irrigation, a pool, a mains-connected rainwater tank or a home business may need extra protection. Not sure? We can inspect your setup and let you know what’s required.
