The valve that stops dirty water flowing the wrong way back in
Water only flows one way because a device somewhere insists on it. When that device gets old, fouled or forgotten, the protection quietly stops being protection. One calibrated visit sorts it, and you can reach us on (02) 9072 0504 to book it.

What we handle every week
Annual compliance, new devices, failed internals and strata registers all fall under the one licence, and every job is quoted in writing first:
Annual compliance testing
The yearly reading. Annual compliance testing checks that your reduced pressure zone device, double check valve assembly or other testable backflow preventer still holds under pressure, with the readings lodged to Sydney Water so your commercial or residential property stays certified and protected.
Testable device installation
New devices, correctly rated. Testable device installation and replacement suits renovated kitchens, new irrigation lines, fire hose reels or any system change that triggers a Sydney Water requirement, with the correct device selected, fitted neatly and commissioned against the hazard rating of your connection.
Failed device repair
Fixing what the test finds. Failed device repair deals with the spring or check valve faults that a test uncovers, and because a single gummed-up check valve is usually the culprit, most repairs cost far less than replacing the whole assembly and restore full certification quickly.
Strata and commercial scheduling
Whole registers, one visit. Strata and commercial scheduling keeps unit blocks near the station and highway precincts compliant year after year because the register records every device on site and a missed annual test can lead to enforcement rather than a simple catch-up booking.

Common backflow device problems
Two failures account for most of the calls, and both are fixable the same afternoon:
The test that comes back failed
Gummed internals. A device that fails its annual test often means a worn check valve, a fouled spring or debris caught in the seat, and because the suburb's older supply runs shed old scale, gummed internals are the commonest cause we find here.
The device nobody knew existed
Inherited compliance. A forgotten device surfaces when a property is sold, tenanted or renovated, and Ku-ring-gai's share of century-old homes means many owners inherit one without knowing, so we trace the register, locate the fitting and bring the certification up to date.
Why staying certified matters more here
Skipping the annual test is not a neutral choice, because the consequences land on the owner, not the device: a contaminated supply, an enforced compliance order and a certification trail that frightens buyers are all far simpler to prevent than to unwind.

How it works
Our backflow 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 and certify
We connect the calibrated test kit to the device's test cocks, run the readings through each check valve and relief valve, compare the numbers against the standard, then lodge the result with Sydney Water the same day.
- 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 Pymble
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 Pymble 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 testing pairs naturally with leak detection, where the same pressure-testing instincts apply, and with the planned checks in maintenance plumbing. The full trade sits under the plumbing hub.
Where we work
Where else we work around the Upper North Shore
From Gordon and Killara down the line to West Pymble, St Ives and Turramurra, the same licensed team carries the same calibrated kit, so every device across the wider Ku-ring-gai area gets tested to one standard by one accountable crew.
Good questions, straight answers
Backflow questions Pymble locals ask
What is backflow and why does it matter?
The basics. Backflow is water flowing backwards through a connection and carrying contaminants into the drinking supply, which is why Sydney Water requires testable devices wherever irrigation, fire services or commercial equipment connect to the potable mains.
Does my property legally need annual backflow testing?
The legal bit. Any property with a registered testable device must have it tested each year by an authorised plumber, and the results go to Sydney Water so the certification stays current on the register.
How long does a backflow test take?
Time on site. A routine annual test usually wraps up within the hour, because the device is isolated, the readings are taken through the test cocks, and the paperwork is prepared while the equipment is still on the line.
What happens if my device fails the test?
Failed devices. A failed device needs repair or replacement before certification can be issued, and because most failures trace to a worn check valve or fouled spring, we carry the common parts and quote the fix first.
Are backflow devices common in older local homes?
Inherited devices. They are, because a century of renovations around the area's Federation homes added irrigation systems, pool fills and outbuildings, and any of those additions can trigger a device requirement that owners inherit on the register.
Who is allowed to test a backflow device?
Who can test. Testing must be done by a licensed plumber who holds Sydney Water backflow authorisation, carries the calibrated kit the standard demands, and lodges the results directly, which describes exactly how our testing team works.
