A real person answers, day or night
The quiet valve standing between your rainwater tank and the town main
Compliance letters are how most owners meet their backflow prevention device, yet it is the one fitting standing between your rainwater tank, irrigation line or workshop equipment and the water the whole street shares. Asquith properties carry more of these devices than most people realise. Ring (02) 9072 0520 and we will handle the device, the test and the paperwork in one visit.
Tanks, irrigation and the connections nobody filed
Residential cross-connections here usually arrived with renovations rather than plans. Detached family homes commonly inherited rainwater tanks and mains-fed garden irrigation from decades of weekend improvements, sometimes plumbed in long before anyone filed a device registration.
The fitting on the line is what decides the obligation, and finding it is the first job. Townhouses nearer the railway station rarely carry tanks at all, so their exposure sits elsewhere, usually at appliance connections or garden taps. Either way, the mechanism either holds pressure or it does not.
What our backflow testing covers
A backflow device is a mechanical fitting with internal springs and check valves that wear with time, so an annual test is a genuine check that the mechanism still holds, not a rubber stamp. Our licensed plumbers test, service, repair and certify every device class:
Annual compliance testing
Every testable device gets isolated, connected to calibrated test equipment and walked through the full pressure sequence, and the certified report is lodged with the water utility promptly, so the annual cycle never slips and the record stays current.
Device repair and rebuilding
Springs, seals and check valves wear with the years, so when the gauge shows the mechanism no longer holds, we strip and rebuild the unit with matched parts instead of defaulting to a full replacement the property may not need.
New device installation
Where a cross-connection turns up on a tank outlet, an irrigation line or a workshop fit-out, we select the correct device class for the hazard rating, install it to standard and register it so the compliance record starts properly documented.
High-hazard and commercial devices
Clubs, schools and workshops carry higher-hazard fittings on their own renewal dates, and we manage that scheduling for owners across the year, so a bowling green's irrigation or a hose reel never becomes the reason a compliance letter turns nasty.
Where we work
Where the testable fittings actually live around here
Compliance letters tend to arrive from predictable corners. Irrigation feeding the local bowling club's three greens is a textbook testable connection, as are the grounds at the schools and the workshops in the industrial pocket. A surprising share of the suburb's devices sit outside ordinary backyards, each on its own annual cycle.
Faults we find during testing
A check valve that no longer seats
Debris and scale stop the internal check valve seating fully, which the pressure test exposes immediately, and because most mechanisms are serviceable a thorough rebuild usually restores full compliance without the cost of replacing the entire fitting.
A connection nobody ever registered
Improvements from decades past sometimes left a tank or irrigation line plumbed in with no device at all, and we fit the correct device class, register it properly and bring the whole property into the compliance system cleanly.
A device buried or boxed in
Fittings hidden behind landscaping or built over during decades of garden improvements cannot be tested until access is restored, so we relocate or rehouse the unit neatly, wherever the regulations and the layout of the property both allow it.
Why it matters: more than a compliance box
- Protecting the drinking supply A mechanism that has let go can allow tank water, irrigation residue or chemical lines to siphon back into the mains, affecting not just your household but the neighbours sharing the same street's supply.
- Avoiding utility penalties An overdue test on a registered device is an enforceable matter, and a routine annual visit costs a fraction of the trouble a lapsed registration brings.
- Catching faults while they are small Annual testing finds a worn seal or a sticky valve while it is a minor rebuild, rather than discovering a corroded, unsaveable device years down the track.
How it works
Our testing process, step by step
- 01
Call and tell us
Ring (02) 9072 0520 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, service and certify
We locate the device, isolate the supply and run the full pressure sequence with calibrated gauges, rebuilding the mechanism where the readings demand it, then lodge the certified report with the regulator so your compliance record is complete and the annual cycle restarts cleanly.
- 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 Asquith
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 Asquith 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 work sits inside our wider plumbing service, alongside maintenance plumbing that keeps household fittings honest and leak detection for supply lines losing water where you cannot see it.
Where we work
Areas we cover for backflow work
Testing runs across the local area and out to North Wahroonga, Hornsby, Mount Colah, Waitara and North Turramurra, with the same licensed testing, fixed pricing and regulator paperwork carried to every property, whether it sits on the ridge or down toward the valley.
Good questions, straight answers
Backflow testing questions Asquith locals ask
How often does a backflow prevention device need testing?
Sydney Water requires most testable devices to be inspected and tested every twelve months, and we set a renewal rhythm for your property so the compliance paperwork never lapses or arrives as a surprise.
What properties actually need a backflow device?
Any property with a connection that could push water backwards into the supply, covering homes with rainwater tanks, garden irrigation, pool fills and fire hose reels, plus the commercial fit-outs around the station.
Do you handle the Sydney Water paperwork as well?
Yes, we lodge the test report and any device registration directly with Sydney Water after the inspection, so your compliance trail is complete without you filling in a single form yourself.
What happens if my device fails its test?
We give you a fixed written price to repair or replace the failed mechanism before any work begins, then retest it so the certification can be lodged and your property is compliant again.
Can older houses have backflow risks too?
They can, particularly established family homes with rainwater tanks, pool fills or garden irrigation plumbed into the mains, all common additions on the older detached blocks around the ridge.
How long does a backflow test take?
A routine annual test on an accessible device usually takes under an hour including the paperwork, and we schedule it around your day rather than leaving you waiting on a vague arrival window.
