A real person answers, day or night

Clean, safe water protection that starts at the meter, not the tap

Every property with a testable device owes the utility a certified result each year, and missing it invites fines. Ring (02) 9072 0520 and we will test, certify and lodge the paperwork, usually within the hour. The broader plumbing work sits on our plumbing hub, and everything we do is reachable from Carlton.

Why this suburb carries more testable devices than most

A suburb of first-generation connections

This is one of the St George district's earliest railway suburbs, so a huge share of properties were connected to the reticulated supply when it first reached the area, and those arrangements have been patched, extended and re-plumbed through every decade since.

Older pipework raises the stakes

Federation cottages still running galvanised supply lines and post-war walk-ups with shared water both present exactly the cross-connection conditions testable devices exist to guard against.

Compliance has caught up with the plumbing

Testable device registrations are now tracked property by property, and an old, densely built suburb like this one carries more registered devices than any newer subdivision ever will.

Backflow work we handle

Backflow compliance is a small, precise field: devices are installed, tested against calibrated gauges and certified to the authority, and we handle every part of that cycle for residential and commercial properties alike.

Annual testing and certification

Every testable device gets exercised each year with calibrated gauges across both check valves, the results are logged against the device serial, and the water authority receives the signed compliance certificate before the due date passes so your registration never lapses.

New device installation

Where a property has no device or an obsolete one, we assess the hazard level, supply and install the right testable valve, whether a reduced pressure zone unit or a dual check, then register and certify the new install properly.

Repairs and replacements

Devices that fail get stripped, cleaned and rebuilt with matched seals and springs where the body allows, or swapped for a new certified unit where they do not, with the retest and the paperwork always completed in the same visit.

Commercial and strata compliance

Cafes, salons, laundromats and unit blocks carry the highest ratings, and we build a register of every device across the site, test them on an annual cycle that suits your operation, and keep certificates ready for any local council inspection.

Fabricating new pipework on site

The shop strip and the walk-ups: where devices cluster

The station-side businesses

The cafe, salon and takeaway strip near the railway station carries the suburb's highest hazard ratings, and every boiler, dishwasher bank and commercial coffee machine on those connections needs a working, certified device behind it.

Shared supply in the brick walk-ups

In the post-war flats, one registered device on a shared line protects every unit connected to it, which makes the annual test a whole-building obligation rather than a single household's paperwork.

A register beats a shoebox of certificates

For strata and commercial owners juggling multiple devices, we keep a dated register so nothing quietly slips a year and nobody discovers it at renewal time.

Where backflow compliance goes wrong

A device that fails its test

A device that fails its annual test usually means debris holding a check valve open rather than a dead unit, so a strip and clean brings most back into range, though bodies with pitted seats genuinely need replacement.

Overdue test notices

Notices arrive from the utility with deadlines attached, and an overdue test can risk fines or supply restrictions, so we prioritise lapsed registrations, test promptly and lodge the certificate the same week to close the notice out.

Contamination after a failure

Cloudy water or an odd taste after a device fails or a repair disturbs the line can signal backflow already occurring, and we flush, retest and, where the risk is real, upgrade the property's protection.

Why staying certified matters

  • The supply is shared A cross-connection at one property can pull contaminants back into the mains serving the neighbours, which is why regulators treat an untested device as seriously as a missing one.
  • Small faults hide inside working devices A valve can pass visually for years while its check valves quietly lose their seats, and only calibrated testing proves it would actually hold in a backflow event.
  • Clean water starts upstream The same thinking that drives filtration, leak detection and water filters applies here: protecting the supply at its source beats reacting after the water has already turned.

How it works

How a backflow test works, step by step

  1. 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.

  2. 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.

  3. 03

    Test and certify

    The device is isolated, connected to calibrated test equipment and put through its full forward and reverse sequence, every result recorded, and the compliance paperwork lodged with the water authority before your plumber packs up the van.

  4. 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 Carlton

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 Carlton 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.

Where we work

Where else we work

Alongside backflow testing in our own patch, we cover Allawah, Beverley Park, Kogarah Bay, Kogarah and South Hurstville, where the same mix of Federation cottages, post-war walk-ups and shopfront businesses keeps testable devices due yearly on nearly every decent-sized site.

Good questions, straight answers

What locals ask us about backflow testing

What is backflow and why does it matter?

Backflow is water flowing backwards through a connection and drawing contaminants into the drinking supply, and a testable device stops it, which is why the utility requires certified annual testing.

How often does a backflow device need testing?

Most testable devices require annual certification, with the due date set on your registration, and high-risk commercial properties can face shorter cycles depending on the hazard rating attached to the connection.

Who needs a testable backflow device?

Any property with a connection the utility rates as a hazard needs one, covering things like irrigation, fire hose reels, boilers, commercial kitchens, medical equipment and shared supply lines in unit blocks.

What happens if my device fails the test?

A failed device cannot simply be logged and left, so we strip or replace the valve, retest it into range and lodge the passing certificate, all normally within the one visit.

What does a backflow test involve and how long does it take?

Your plumber isolates the line briefly, connects calibrated gauges and runs the device through its checks, and most residential tests are finished inside an hour with paperwork lodged the same week.

What happens if I ignore the test notice?

An overdue registration can attract penalties and, in serious cases, supply action from the utility, so the better move is booking the test before the due date and keeping your certification continuous.
