A real person answers, day or night
The quiet valve your water supply depends on
Backflow prevention devices sit on supply lines and only matter when water tries to run the wrong way, so they get forgotten until a compliance notice lands. One call sorts the test, the paperwork and any repair, and the broader picture lives on the North Sydney home page.
Where testable devices cluster locally
- The commercial spine The office and retail strip through Miller Street carries restaurants, medical suites and gyms, the exact premises classes Sydney Water requires to hold registered, testable devices on their supply lines.
- Facilities with serious hazard ratings The Mater Hospital on Rocklands Road is the clearest local example of a property where protecting the potable supply is not negotiable, and its devices earn meticulous annual attention.
- A clock that never stops Every registered device owes a test each year, the result gets lodged against its registration number, and we track due dates for commercial clients so the reminder letter never arrives first.
What we test, repair and certify
Every job below starts with a proper diagnosis and ends with paperwork you can file, whether the property is a single café tenancy or a tower with a dozen registered assemblies.
Annual testing and certification
Each testable device, from a simple dual-check valve to a full reduced pressure zone assembly, gets isolated, gauged and verified against the standard, with the passing result lodged and your compliance certificate issued before we pack up.
New device installation
Renovations, tenancy fit-outs and irrigation connections often trigger a requirement for a new testable assembly, so we size the right device for the hazard rating, register it with Sydney Water and certify it from its very first day.
Device repair and rebuild
A device that will not hold its test usually needs fresh seals, springs or check internals rather than whole replacement, and we carry common rebuild kits on the van so most failed assemblies pass again the same visit.
Lodgement and record keeping
The test means nothing until it is filed, so we handle the registration paperwork, keep copies of every certificate and flag the next due date so the property never drifts into non-compliance unnoticed.
Strata and commercial programs
Buildings carrying multiple devices, like the mixed-use complexes through the commercial core, get a coordinated annual program where every assembly is tested in one scheduled visit and the committee receives a single consolidated report.
When a device fails or goes missing
Failed test internals
A device that drops pressure across a check valve or dumps water through its relief port has worn internals or debris caught in the seat, and a rebuild with quality parts usually restores it without replacing the whole assembly.
Unregistered older devices
Buildings from the pre-1940 terraces to the 1960s walk-ups often carry devices nobody ever registered, and we identify them, register them and bring them into the annual cycle before an inspection finds them first.
Overdue compliance notices
A notice from Sydney Water or council starts a clock, so we prioritise those jobs, test or replace whatever is needed, lodge the result and hand over the paperwork that closes the notice out properly.
Old stock, hidden assemblies
The 1960s-1980s walk-up flats were plumbed before cross-connection control tightened up, so forgotten check valves still surface on laundry and boiler lines at first inspection. Heritage terraces converted to cafés along the character streets often carry a device fitted during the fit-out and never registered, which is how a compliance notice arrives years later.
Why staying certified matters
A skipped test is not a victimless delay, because the consequences land on the drinking water, the ledger and the building itself, usually all three at once:
- Protects the drinking water A cross-connection without a working device can pull contaminated water back into the potable supply, and a verified annual test is the only proof it will hold when a pressure drop actually happens.
- Keeps you legally compliant Testable devices are a Sydney Water requirement, and an untested or failed device leaves the owner exposed to compliance action, so the annual certificate is your record that the duty was met.
- Stops damage before it starts A failing device often signals broader supply problems, and catching it during the annual visit means small repairs now instead of a contaminated line or a flooded plant room later.
How it works
How the visit works
- 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, repair and lodge
We isolate the line, fit the gauge and verify the assembly against the standard, rebuilding any internals that fail, then retest until it holds and file the certificate with Sydney Water the same day.

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 North Sydney
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 North Sydney 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 certification pairs naturally with our broader maintenance plumbing program, where annual device testing can be bundled with the routine checks that keep a building's whole supply side healthy, and our water filters work covers the downstream side of protecting what pours from the tap.
Where we work
Properties we cover around the area
We test devices across the area and the adjoining suburbs of McMahons Point, Crows Nest, Cammeray, Neutral Bay and Waverton, where the mix of commercial fit-outs, older terraces and modern towers means every street carries a different combination of registered devices and hazard ratings.

Good questions, straight answers
Backflow questions North Sydney locals ask
How often does a backflow prevention device need testing?
Testable devices must be verified every twelve months by a licensed plumber with backflow accreditation, and the annual rhythm is set by Sydney Water rather than by the property owner.
What happens if my device fails its test?
We repair or replace the failed internals, retest until the device holds, and lodge the passing result so your property stays compliant without a second call out.
Do apartment buildings around here need backflow testing?
Yes, the tower and walk-up stock around the station precinct commonly carries testable devices on shared supply and fire lines, and strata managers are usually the ones who book the annual visit.
Who is responsible for the device on my property?
The property owner carries the legal responsibility for the device and its annual certification, whether that owner is a homeowner, a strata scheme or a commercial tenant under lease terms.
How long does a backflow test take?
Most single-device tests wrap inside an hour including the paperwork, and we give you a fixed written price before any tool comes off the van.
What does a backflow test cost?
The call out is $0 and the price depends on how many devices your property carries and their condition, so we inspect first and quote the full job in writing before starting.
