One Small Valve Carries a Big Legal Duty
A backflow prevention device is a one-way gate on your water supply, and it only earns trust while a licensed plumber tests it on the schedule the register sets. Skip the test and the paperwork lapses, and the mechanism wears unseen.
The property carrying the device wears the risk. We keep the routine simple: book, test, report, done.

Managers need dates they can trust
Backflow Services We Cover
Backflow work spans the whole life of a device, from first registration through yearly testing to eventual repair or replacement, and each service below feeds the one after it:
Annual device testing
Annual testing. Our tester isolates the supply, connects calibrated gauges, runs the pressure and relief checks the Australian Standard requires, records the readings honestly and lodges the report, because a marginal device today costs less than a contaminated supply tomorrow.
Device installation and registration
Installation and registration. New premises, renovations and changed hazard ratings trigger correctly rated devices, so we size and install the right containment or zone protection, register it with Sydney Water and leave the compliance certificate with your paperwork from day one.
Repairs and internal replacement
Repairs and internals. Worn seals, seized check valves and fouled relief ports sit behind most dropped readings, and replacing the internals of a serviceable device costs less than a full swap, so we quote the honest option in writing first.
Compliance reporting and lodgement
Reporting and lodgement. Every test generates a report that must be lodged with the water authority and kept on file, and we handle the lodgement, hand you a copy and flag the next due date so the register stays clean without you chasing.

Common Backflow Problems We Fix
The failed annual test
The failed annual test. A dropped reading usually traces to a worn seal or debris under a check valve, faults that develop quietly between visits; most are repairable the same call, and the retest confirms the fix on paper rather than in hope.
The device nobody can find
The device nobody can find. Older commercial premises and repiped buildings often hold units buried behind fitouts or in forgotten plant corners; we trace the supply, locate and identify every device, and bring the whole register up to date again.
The expired registration
The expired registration. A missed test date sits quietly on the authority's register until a notice arrives, by which point the property is formally overdue; we test promptly, lodge the report, clear the notice and set reminders so it never repeats.
Why Staying Compliant Matters
- Contaminated water travels backwards, not just forwards A pressure drop on the main can siphon whatever sits on your side of the device straight into the supply, and the property at the cross-connection wears the liability.
- The register follows the property Overdue devices surface during strata audits, business transfers and insurance claims, and clearing a legacy non-compliance always costs more than the annual test ever did.
- A small test beats a big replacement Yearly testing catches wear while it is still a seal and a service, rather than a corroded body and a full swap, and that gap is exactly what the yearly visit exists to close.
How it works
The Testing Process, Step by Step
- 01
Call and tell us
Ring (02) 9072 0528 and describe what's happening, and a licensed plumber, not an answering machine, will tell you what it likely means, what to stop using, and when we can realistically be there.
- 02
Quote before work
Your plumber inspects the job properly, runs whatever diagnosis it genuinely needs, and hands you a single fixed written price covering the complete fix, with a $0 call out fee and nothing added afterwards.
- 03
Test, fix and retest
Test, fix and retest. The device is isolated and tested with calibrated gauges against the standard's thresholds, and if the reading falls short, worn seals or valves are replaced from the van before the full test runs again so the report reflects a pass.
- 04
Backed for life
Everything we complete is covered by our Lifetime Labour Warranty, the promise that outlasts the job itself: if it's not right, we come back. No questions. No cost.
Why Choose Your Plumber Neutral Bay
Fixed prices, kept
Every job is priced upfront in plain writing before any work starts, the invoice always matches that number, and weekend or late-evening timing changes nothing, because overtime rates simply don't exist here.
Licensed and insured
Your Plumber Neutral Bay works under licence #275278C with full insurance behind every job, and the compliance certificates that protect your home's paperwork trail arrive with the invoice, without you ever needing to ask for them.
Lifetime Labour Warranty
Workmanship here is guaranteed for life under our Lifetime Labour Warranty rather than for a warranty card's fine-print window, which says more about how the work is done in the first place than any advertisement could.
Genuinely local response
We work these streets constantly rather than commuting in from across Sydney, so the van reaching you has usually just left a job nearby, stocked for the faults the local houses actually develop.
Backflow sits inside our wider plumbing services stream, and a test visit often flags the corroded fittings worth chasing through leak detection or the tired filter housing our water filters team can service on the same round.
Where we work
Areas We Service
Testing follows the devices, from the apartment blocks and tenancies around the Junction through Cremorne, Kirribilli, North Sydney, Cammeray and Kurraba Point, with strata and commercial registers kept on their renewal dates so multi-property owners never chase a missed test.
Good questions, straight answers
Backflow Questions Neutral Bay Owners Ask
How often does a backflow prevention device need testing?
Annually, in most cases. Sydney Water sets the cycle by each device's hazard rating, so we test on the schedule your property's registration demands and lodge the report for you.
Which properties need a backflow prevention device?
Any cross-connection property. Anything that could push contaminated water back into the supply needs a device, covering cafes, apartment blocks, buildings with fire hose reels and homes with irrigation or rainwater plumbing.
What happens if my device fails its test?
We repair and retest. A fixed written price covers the repair or replacement, the work happens the same visit wherever the van carries the part, and the retest signs the compliance paperwork off properly.
Do you test devices in apartment buildings and commercial premises?
Yes, constantly. Much of our work is testing containment and zone devices across the unit blocks and hospitality premises that dominate the suburb, coordinated with strata managers and business owners.
How long does a backflow test take?
Usually under an hour. A standard test covers isolating the line, running the procedure, refilling the supply and completing the report, so most premises barely notice the interruption to their day.
Who lodges the test report with Sydney Water?
We lodge it for you. As a licensed contractor we submit the report to the water authority and hand you a copy, which matters for strata registers, council audits and insurance documentation.
