A real person answers, day or night
Clean water stays clean only while the device between the mains and your taps holds
A backflow prevention device is the one-way valve standing between the mains supply and everything downstream of it. When it fails, contaminated water can siphon backwards into clean lines. Call (02) 9072 0504 and we will sort it.

What we test, fit and certify
Testing, installing and certifying are three different jobs, and each one follows the same pattern: assess the hazard, do the work properly, and leave you with certification paperwork that stands up to scrutiny from the authority. Everything here sits inside the broader plumbing services we cover across the area.
Annual testing and certification
Every device is tested against Sydney Water's requirements, the results go on the test tag and report, and your certification is lodged with the water authority so the annual compliance cycle closes on time without a second visit from us.
New device installation
Renovations, new irrigation and added fixtures all change what a property needs, so the right testable device is selected for the hazard level, installed to the Australian Standard and certified from its very first day of service at the property.
Device repair and replacement
A device that fails its annual test is not automatically a replacement job, because many units are rebuilt with new internal check valves and seals, given a fresh test and returned to service with a passing certificate the same day.
Irrigation and commercial devices
Garden irrigation on large blocks and small commercial tenancies around the village each carry their own contamination risks, so devices on those lines are tested, maintained and documented to suit the specific property and its water use all year round.
From the station to the village shops
Tenancies with their own obligations. The retail strip around the village shops and the streets feeding the railway station hold small commercial tenancies, and food premises in particular carry stricter backflow requirements than a standalone house. A cafe's coffee machine and dishwasher lines, an irrigated verge or a hairdresser's basins can each shift a property into a higher hazard rating, which changes the device it needs and how often it must be tested. We test, replace and document those devices so the annual paperwork is one less thing to chase.
When a device raises a red flag
A failed annual test
A device that will not hold pressure usually has worn check valves or debris caught in the seat, and most of these faults are repaired on the spot with the correct kit before a fresh test confirms the fix.
Visible corrosion or weeping
Older assemblies sitting in damp garden beds or corroding plant rooms weep at the joints, and because replacement bodies are always stocked on the van, a tired device is swapped and certified during the one visit.
Notice from the water authority
A compliance letter in the mail starts a clock, so the device is tested promptly, the report is lodged correctly and the property stays on the right side of the annual requirement without any added stress.
Why it matters more than the tag on the pipe suggests
A backflow device is the last line of defence between contamination and the glass on your bench: when it holds, the supply stays clean, and when it fails, the consequences reach every outlet in the home.
- Protecting every tap in the house A failed device can let garden chemicals, greywater or stagnant water draw back into the drinking supply, and the first sign is often a strange taste nobody can explain. Annual testing removes the guesswork.
- Keeping the compliance clock quiet Sydney Water notices arrive with deadlines, and a lodged test report closes the requirement for another year without penalty risk or follow-up letters.
- Small faults, caught early A device serviced on schedule rarely fails suddenly, so the annual visit doubles as an early warning for the wider pipework, sitting naturally alongside leak detection and a booked maintenance plumbing round. Households focused on water quality often pair the check with water filters as well.
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
Inspect and test the device
The device is isolated from supply, tested with calibrated gauge equipment, and where a fault shows it is repaired or rebuilt with the correct internals, then the line is returned to service and the results are recorded properly.
- 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 Roseville
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 Roseville 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.
Certification visits are one slice of the trade, and the same crew handles everything from dripping taps to full drainage renewals.
Where the test van travels
Backflow testing runs from the village out through Lindfield, Killara, Chatswood, Roseville Chase and Castlecrag, with the same fixed written pricing and $0 call out applying wherever the van stops across these North Shore streets every week of the year.
Good questions, straight answers
Backflow testing questions from Roseville locals
How often does a backflow prevention device need testing?
Sydney Water requires most testable devices to be tested annually, and the report must be lodged by a licensed plumber with backflow accreditation before the compliance deadline on your notice passes.
What happens if my device fails its test?
Most failed devices are rebuilt with new check valves and seals and given a fresh test before the paperwork is lodged, and a body beyond repair is swapped out the same visit.
Does my property actually need a backflow device?
Properties with irrigation, certain appliances or commercial water use generally do, and a licensed plumber can assess the hazard level and tell you honestly whether a testable device is required at your address.
How much does backflow testing cost?
You receive a single fixed written price before any work begins, the call out fee is $0, and the invoice always matches the quote with no hourly rates or overtime additions.
Are your testers licensed for backflow work?
Every plumber who tests or installs a device holds the appropriate licence and accreditation, works under licence #275278C and lodges the certification paperwork with the water authority on your behalf.
Can you test devices in older heritage homes?
Yes, devices are tested and replaced in heritage streets without disturbing period gardens or brickwork, and any new assembly is fitted to suit the existing pipework and the character of the property.
