What is a backflow device tester?
A backflow device tester is a licensed plumber who inspects and maintains equipment that protects the clean water supply. CRG uses specialised tools to confirm each unit works correctly and meets applicable requirements.
Why Backflow Prevention Devices Require Checking
Water should normally travel in one direction through a plumbing system.
However, pressure changes can cause water to flow backwards. This may allow contaminated water to enter the drinking water supply.
A backflow prevention device stops this reverse flow. Yet worn valves, damaged seals and other faults can affect its operation.
Regular testing confirms whether the device still provides the required protection.
When Is Testing Required?
High and medium hazard devices must be tested when they are installed. They must then be tested every year.
Testing may also be required after repairs or maintenance affecting the device.
You may receive a letter from Sydney Water advising that your device is due for testing. However, the property owner remains responsible for arranging the test and maintaining the device.
An accredited plumber must complete the test and submit the result to Sydney Water.
What Happens During a Test?
CRG will arrange a suitable time to attend your property. Our accredited plumber will inspect the device and connect calibrated testing equipment. The plumber then checks the valves and internal components.
The test identifies pressure loss, water leakage and other signs that the device may not operate correctly.
Once testing is complete, we will advise whether the device passed. CRG will then prepare the required report, submit the result to Sydney Water and provide you with a copy.
What Happens If the Device Fails?
A failed test does not always mean the entire device must be replaced.
In some cases, cleaning or replacing a worn component may solve the problem. Older or badly damaged devices may require more extensive repairs or replacement.
The device must pass a further test after the required work is completed.
CRG can explain the reason for the failure and recommend the appropriate next step.

How Much Does Backflow Testing Cost?
CRG charges $250 for the first valve and $170 for each additional valve tested during the same visit.
Repairs, replacement parts and retesting may involve additional charges.
The total price can also depend on the number of devices and their accessibility.
See our detailed guide to costs for more information.
Annual Testing Reminders
Annual testing dates can be easy to overlook.
This is particularly common when a business manages several properties, services or compliance requirements.
When CRG completes your test, we can record the next due date. We will then contact you approximately one month beforehand.
This provides enough time to arrange the next appointment before Sydney Water sends further reminders.

Backflow FAQs
What is device testing for?
Device testing checks your backflow prevention devices annually (as mandated by law) to ensure dirty or contaminated water does not flow back into Sydney Water’s supply. This problem can occur if the main system loses pressure for some reason. The testing can only be done by an accredited backflow plumber.
What is involved in device testing?
The testing process involves using a flow testing kit. Accredited plumbers will close valves and checking for changes in gauge movement, water leaks and other signs. The flow testing kit is tested and calibrated by an approved authority annually.
Is device testing necessary?
By law, a boundary backflow prevention device must be checked annually by an accredited and licensed plumber in NSW.
How much does it cost to have a backflow device checked?
Testing costs $250 for the first valve, and $170 for each additional valve. Yearly testing is mandatory, and it ensures that your system blocks the backflow into Sydney Water. A report is submitted to Sydney Water for registration, and some plumbers provide yearly reminders as well.
How often is device testing required?
In NSW backflow prevention devices are required to be tested annually (and upon installation or repair).
Who is responsible for arranging a device test?
The property owner is responsible for ensuring the correct device is installed, maintained and tested when required. A property manager, tenant or facility manager may arrange the appointment. However, the owner remains responsible for ensuring the property meets applicable backflow prevention requirements.
Who can perform testing on backflow devices?
Testing must be completed by a licensed plumber with the appropriate backflow accreditation. General plumbing experience alone does not qualify someone to test and certify a testable device. CRG Plumbing & Maintenance provides accredited testing and completes the required reporting.
What happens after the device has been tested?
CRG will advise whether the device passed or failed. We will then complete the required report and submit the result to Sydney Water. You will also receive a copy for your records. If the device fails, we will explain what repairs may be needed.
Can CRG test more than one device during the same visit?
Yes. CRG can test several backflow prevention devices during one appointment. Testing multiple devices together may reduce the cost per device. Please advise us how many devices are located at the property when arranging your booking.
Can a backflow device be repaired if it fails?
Many failed devices can be repaired by cleaning the unit or replacing worn components. However, severely damaged or outdated devices may require replacement. The device must be retested after repairs before it can receive a passing result.
