A real person answers, day or night
The quiet valve standing between your garden and your drinking water
Year after year the device on your supply line does nothing at all, until pressure drops and it becomes the only barrier protecting your household taps. The annual test proves that barrier still holds, and Sydney Water requires it every twelve months from an accredited plumber.
Devices on leafy blocks and along the highway strip
Irrigation on generous gardens
Commercial tenancies near the station
Fire services on larger holdings
Backflow testing services
Here is what the job covers with us: the annual test and lodgement, servicing and rebuilds when a device fails, new installations and registrations for renovated properties, and the recovery of hardware that earlier renovations buried or boxed in.
Annual testing and lodgement
Registered devices protecting irrigation systems, fire services and commercial fitouts are tested every twelve months using calibrated gauges, and the passing result is lodged with Sydney Water promptly so your property's compliance record stays current without any follow-up notices arriving.
Servicing and rebuilds
Device servicing and rebuilds restore worn check valves and fouled relief valves with matched parts, which usually brings a failing unit back to standard without the cost of full replacement, and the retest gets lodged straight away rather than weeks later.
New devices and registration
New device installation and registration covers renovations and new connections that trigger a backflow requirement, with the hazard rating assessed, a compliant unit fitted and the registration lodged so the testing schedule starts on the correct footing from day one.
Finding forgotten devices
Forgotten device location and recovery suits older holdings where renovations boxed in or buried equipment decades ago, and once the unit is exposed it either returns to service or gets replaced with a modern, properly registered and fully compliant equivalent.

What the test picks up
Check valves that fail
A device that fails its check valve test is usually letting water creep backwards past debris or a worn seat, and a service or rebuild restores the seal in most cases without needing a complete replacement unit.
Relief valves that weep
A relief valve that discharges or weeps points to pressure fluctuations or a fouled valve, a fault common where reactive clay soil movement stresses buried supply runs, and it is corrected before it floods a garden bed.
Why it matters: the cost of letting compliance lapse
- Drinking water you can trust A failed device can draw irrigation water, fertiliser or garden chemicals back into household supply, and the people who drink it sit at your own table.
- Notices that escalate Sydney Water tracks overdue tests against registered properties, and an unresolved notice becomes a real problem when you sell or renovate.
- Replacement avoided A device left untested corrodes and seizes until testing becomes replacement, so the annual visit keeps a small job small.
How it works
The testing process, step by step
- 01
Call and tell us
Ring (02) 9072 0504 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, lodge and confirm
We connect the gauges, run the check and relief valve sequence and record every reading, then either lodge the passing report with Sydney Water that week or explain the fault, quote the fix and retest once it is resolved.
- 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 Killara
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 Killara 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.
Compliance work suits us because it rewards the same habits as every other job here: careful diagnosis, honest reporting and paperwork that stands up when someone official reads it.
Backflow testing sits within our wider plumbing services, pairs naturally with leak detection since both read pressure behaviour, and folds neatly into scheduled maintenance plumbing visits. Where a device chamber sits near old earthenware drainage, our CCTV drain inspections team often works the same trench line.
Where we work
Areas we service
Testing covers the whole local area and the neighbouring suburbs of Gordon, Lindfield, East Killara, Roseville and Pymble, with accredited plumbers, calibrated gauges and report lodgement carried in every van, whether the device protects a garden irrigation system or a commercial fitout.
Good questions, straight answers
Backflow testing questions Killara locals ask
How often does a backflow prevention device need testing?
Once a year, in most cases. Annual testing is the standard requirement for registered devices in NSW, and the exact interval applying to your property is confirmed on the registration notice Sydney Water issues.
Who can test a backflow prevention device?
Accredited licensed plumbers only. Testing and report lodgement require a licensed plumber holding backflow accreditation with Sydney Water, and every plumber we send to your property carries that accreditation.
What happens if my device fails the test?
We quote the fix first. The failed component is explained plainly, a fixed written price for the repair or replacement is approved before any work begins, and the retest is lodged promptly once resolved.
Do I need a backflow device on my property?
It depends on your connections. Properties with irrigation systems, fire hose reels, commercial kitchens or certain plumbing arrangements usually require a device, and an assessment of your setup confirms what applies.
Does testing disrupt the water supply?
Briefly, and by arrangement. Testing shuts the water off while gauges are connected, usually for well under an hour, and the visit is scheduled at a time that suits your household.
What does backflow testing cost?
A fixed price, approved upfront. The call out is $0 and you receive a fixed written price covering the test and report before any work begins, so the figure you approve is the figure you pay.
