Annual RPZ Testing – Sydney Water Requirements
Is Your Backflow Valve Due for Testing?
Sydney Water requires applicable medium- and high-hazard backflow prevention devices to be tested when installed and every 12 months afterwards by an accredited backflow plumber.
Test results for registered containment devices must be submitted to Sydney Water within the required timeframe.
If you've received a Sydney Water backflow testing reminder, contact Shire Care Plumbing to arrange the appropriate service.
Backflow Prevention for Local Businesses & Properties
We assist with backflow prevention enquiries for:
Cafés, restaurants and takeaway shops
Hairdressers, salons and retail premises
Medical and dental practices
Small workshops and commercial units
Strata buildings and apartment complexes
Residential properties with specialised plumbing or water systems
Not every property requires an RPZ valve. The correct backflow prevention device depends on the site's hazard rating and applicable plumbing requirements.
What Is an RPZ Valve?
An RPZ valve, also called a Reduced Pressure Zone Device (RPZD), helps prevent potentially contaminated water from flowing backwards into the drinking water supply.
RPZ devices are used for appropriate high-hazard applications.
Other properties may require a testable double check valve (DCV) or another approved backflow prevention arrangement.
Our team can help arrange an assessment of the appropriate protection for your property.
RPZ Valve Repairs & Replacement
Has your backflow valve failed its annual test, started leaking or been identified as faulty?
We can investigate suitable RPZ and backflow prevention devices and arrange repairs, servicing or replacement where appropriate.
Corrective work and retesting may be required before a device meets its applicable compliance requirements.

Frequently Asked Questions
How often does an RPZ valve need testing?
Applicable testable backflow prevention devices require testing on installation and annually thereafter under Sydney Water's requirements.
Who can test an RPZ valve?
Testing must be carried out by a licensed plumber with the appropriate backflow prevention accreditation.
Does every business need an RPZ valve?
No. The required device depends on the property's assessed hazard rating. Some properties require a testable double check valve rather than an RPZ device.
What happens if my RPZ valve fails?
The valve may need servicing, repair or replacement, followed by appropriate retesting and documentation.
Can you help with a Sydney Water reminder notice?
Yes. Contact us with the notice and details of your device so we can arrange the appropriate testing and reporting.
