A real person answers, day or night
The one valve standing between your taps and everything behind the meter
A pressure change can pull water backwards through a pipe, carrying whatever it touched along with it. A testable prevention device stops that, and the law says it must be proven working every year.
It is one of the quietest jobs on the Kirribilli plumbing calendar, and one of the easiest to let slip. Call (02) 9072 0528 and we will tell you where your property stands.
Salt, slope and stacked supply lines
Backflow devices behave differently on this peninsula than they do inland, for reasons the geography writes itself.
- Salt eats the hardware Salt-laden harbour wind corrodes test cocks, springs and valve seals years ahead of inland service life, so devices on foreshore-side buildings fail their annual test more often than the paperwork expects.
- Steep ground changes the pressure story The peninsula falls sharply toward the water, which means supply pressures and siphonage risks vary street by street, and the correct device rating changes with them.
- Density multiplies the stakes Census figures put roughly 87 per cent of dwellings here in the flats or apartments column, so one contaminated riser in an interwar block is never just one kitchen's problem.
How it works
The testing work, start to finish
Backflow testing covers several distinct jobs, and the right one depends on what sits on your meter today.
Each property is assessed on its own supply before any device is touched, because the hazard rating decides what compliance actually requires.
- 01
RPZ valve testing
We test reduced pressure zone devices by isolating the supply, connecting a calibrated gauge kit and recording both pressure differential readings, confirming the valve would hold under back-siphonage before lodging the compliant result with Sydney Water on your behalf.
- 02
Dual check valve testing
Dual check valves protect smaller supplies, and we test them the same rigorous way, isolating the line, attaching the kit and verifying both check seats seal, so a tenanted flat's meter stays compliant year after year without disruption.
- 03
Testable device installation
Where a property lacks a compliant device, we size and install testable backflow prevention matched to each property's hazard level, working through rendered double-brick walls and tight older plant rooms common in the peninsula's interwar apartment stock and heritage-era buildings.
- 04
Annual certification and lodgement
Sydney Water requires testable devices to be certified annually, and we schedule the reminder, perform the test and lodge the official paperwork, so compliance never lapses across a busy strata scheme or commercial tenancy portfolio.
- 05
Whole-building testing programs
Apartment blocks, cafes and heritage properties each carry different hazard ratings, and we survey the supply, recommend the right assembly for the risk and keep every device in the building on one coordinated annual testing schedule tailored to each building.
From heritage pubs to harbourside strata
The mix of premises here makes testing schedules genuinely varied, and we plan around them rather than treating every call the same.
- The Art Deco Kirribilli Hotel, standing since 1937 beside the rail line, carries the heavy commercial hazard rating that hospitality demands And its device gets the full differential test with minimal disruption to trade.
- Food and drink premises along the village strip above the water need annual certification timed to their audit calendar So we book ahead and keep certificates current rather than reacting to notices.
- Walk-up blocks near Milsons Point railway station often hold shared devices on a single meter And we coordinate testing with the owners corporation so one visit covers the whole building.
Where devices fail and certificates lapse
Most backflow problems announce themselves quietly, and knowing the signs is most of the battle.
A device that fails its test
A device that fails its annual test usually shows a leaking relief valve discharge or a stuck check seat, often after years of salt-laden harbour air corroding springs and seals, and it can normally be rebuilt or replaced quickly.
An overdue certificate
An overdue test certificate triggers Sydney Water notices and, left long enough, enforcement action against the property owner, a stressful position we resolve by testing promptly, repairing what fails and lodging the fresh result the same week.
The wrong device for the risk
A device rated below the property's actual hazard level fails council and utility audits during renovations or tenancy changes, and we match the assembly properly to the risk rather than patching hardware that was never adequate.
What an overdue certificate risks: three reasons to stay ahead of it
Contaminated water is a health issue, not a paperwork issue
A failed device can let garden fertiliser, cleaning chemicals or greywater siphon back into drinking supply, and in a building sharing one riser, that reaches every tap at once.
Enforcement lands on the owner
Sydney Water chases lapsed certificates through the property owner of record, and unresolved notices escalate to penalties and, in serious cases, supply restriction until the device is proven.
Sales, leases and renovations all ask for it
A current certificate is one of the first documents requested at settlement or tenancy change, and a missing one stalls deals while the testing gets done in a hurry.
Staying current pairs naturally with other supply protections too, from water filters for drinking quality to leak detection for the losses a test will not show.
How it works
How the annual test works, 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, certify and lodge
We connect the calibrated kit to the testable device, capture upstream and downstream readings, rebuild or replace anything outside tolerance, and lodge the certified result with the utility, so the certificate lands in your inbox without a chase.

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 Kirribilli
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 Kirribilli 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.
Accredited testing is the part most general plumbers cannot offer at all, and it sits inside a full plumbing service rather than beside it.
Where we work
Areas we service
The testing rounds reach wherever the van is needed across the peninsula's neighbours: Milsons Point and Lavender Bay just over the boundary, Kurraba Point along the foreshore, plus McMahons Point and Cremorne Point, each covered by the same accredited, fixed-price service.
Good questions, straight answers
Questions locals ask about annual testing
How often does a backflow prevention device need testing?
Sydney Water requires every testable device to be certified once a year by an accredited plumber, and the registered result must be lodged before the deadline or compliance notices start arriving.
What happens if a device fails its test?
A failed device gets isolated, rebuilt or replaced with hardware matched to the property's hazard rating, and the fresh result is certified and lodged so the site returns to full compliance.
Do apartment blocks need backflow prevention too?
Every property with a testable device on its meter, including strata schemes in older walk-up buildings, carries the same annual obligation, and the owners corporation typically books and pays for the test.
Can cafes and commercial premises fail an audit?
Food premises near the ferry wharves and the village shops carry higher hazard ratings, and an untested or undersized device fails utility audits, so we match the hardware to the risk.
What does an annual backflow test involve?
A licensed plumber isolates the supply, attaches a calibrated gauge kit, records the pressure differentials across the device and lodges the result, all without disrupting the property's water for long.
How much does a backflow test cost?
Pricing is given upfront and in writing before any work starts, covering the test, any minor repairs the device needs and the lodgement, with no call out fee added to the invoice.
