A real person answers, day or night

The one-way valve that protects every glass you pour

A backflow device sits between the town main and anything that could contaminate it, and it only earns trust while it is tested. We carry calibrated equipment, lodge the results ourselves and keep the compliance record current, so the water at your kitchen tap stays the water the utility delivered.

Why the peninsula carries more devices than you would think

The hospital on the ridge

HammondCare's facility on River Road runs palliative care and rehabilitation equipment that sits squarely on a backflow register, the kind of connection that demands properly certified protection year after year.

Strata plant near the highway

The apartment blocks on the Pacific Highway edge carry irrigation systems, fire services and shared plant, all of which land on the register and all of which need an annual test to stay legal.

Old supply lines feeding old valves

Unrenovated Federation homes on the point still draw water through corroded galvanised services, and the scale those lines shed fouls check valves, which makes failed tests more common here than in newer suburbs.

What our backflow work covers

Every device on your register gets tested to Sydney Water's standard, with the results lodged and the paperwork sorted, covering annual certification, new installations, repairs and strata programs, all priced upfront before a tool comes off the van:

Annual testing and certification

Every testable device on your register, from boundary containment assemblies to zone protection valves, gets tested with calibrated gauges against Sydney Water's standard, the results lodged directly by us, and the next due date recorded so compliance never quietly lapses.

Device installation and upgrades

A renovation, new irrigation or a change in how a property is used can trigger a device requirement, and we size the right unit for the hazard rating, from a simple dual-check valve to a full reduced pressure zone device.

Repairs and replacement

A failed reading traces to a worn seal, a fouled check valve or debris in the seating rather than a dead device, so we strip, clean or reseat the mechanism on the spot and only replace where repair is uneconomic.

Strata and commercial programs

Apartment blocks and commercial sites carry multiple devices on different due dates, which is how registers get messy, so we build an annual schedule across the site, coordinate access with the strata manager and issue a certificate for every device.

Fabricating new pipework on site

Where local conditions shorten a device's working life

Salt near the water

Steep double-sided falls drop many devices into low, awkward positions near the foreshore, where salt in the air corrodes exposed test cocks and isolation valves faster than it would inland, so we flag corrosion before it becomes a failed certificate.

A century of services upstream

Pre-war earthenware drainage beneath character streets such as St Vincents Street is a reminder of how old this peninsula's infrastructure runs, and a cross-connection on an older property is never a theoretical risk here.

When a device gives trouble

Three failures account for most of the backflow callouts we run, and each has a straightforward path back to a passing certificate:

Readings out of tolerance

A device that reads out of tolerance usually has a worn seal or debris stirred up by corroded old supply lines, and because we carry the common service kits on the van, most failures are cleared and recertified within a single visit.

Lapsed or lost certificates

Properties change hands, strata managers move on, and suddenly nobody knows when the device was last tested, so we audit the register, test whatever is overdue, lodge the results and rebuild the schedule before reminders escalate to a formal notice.

Devices nobody can find

Older homes and long-held commercial sites often hide a device behind landscaping, under stairs or boxed in during a past renovation, and we trace the register, locate the hardware, restore access and quote a relocation where the setout no longer meets standard.

Why staying certified matters

  • Contamination travels backwards without warning A drop in main pressure from a break or a fire brigade drawing heavily nearby can siphon pool water, irrigation runoff or chemical lines into your household supply, and the first sign is often the taste of it at the kitchen sink.
  • An overdue test compounds Reminder letters become compliance orders, and for commercial and strata properties a lapsed register can affect insurance and sale settlements, which costs far more than an annual test booked on time.
  • A tested device protects the street Where century-old supply lines run between close-set peninsula homes, one unprotected cross-connection can push contamination back toward neighbours on the same run, which is why the register protects more than a single address.

How it works

The testing process, step by step

  1. 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.

  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, certify and lodge

    We isolate the supply, connect equipment to each device and record the check, relief and pressure readings against the standard, certifying passing devices on the spot while anything that falls short gets an explanation, a fixed quote and a retest.

  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 Greenwich

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 Greenwich 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 sits on the supply side of the trade, the same territory our leak detection team works when a line loses water somewhere it should not. The plumbing hub lists every service we run, and maintenance plumbing is where annual device checks can sit alongside a whole-house inspection.

Where we work

Where we test beyond the peninsula

Our rounds cover the whole peninsula and run out to Northwood, Wollstonecraft, St Leonards, Longueville and Waverton, with strata registers near the highway and commercial sites around the village shops held to the same annual program as a single home device.

Good questions, straight answers

Backflow questions Greenwich locals ask us

How often does backflow prevention testing need to be done?

Every twelve months for most devices. Sydney Water requires testable devices to be inspected and certified annually, and we handle the scheduling, the testing and the lodgement so your compliance never lapses without you tracking dates.

Does my property actually need a backflow device?

Usually yes, and we can tell you. Properties with irrigation, fire hose reels, commercial kitchens, medical equipment or shared strata systems generally need one, and we assess your plumbing against the hazard rating to tell you honestly.

What happens if my backflow device fails its test?

Repair, retest, recertify. We quote the fix with a fixed written price, complete the work, retest the device and lodge the passing certificate so your compliance record is restored.

Can you test devices in apartment blocks near St Leonards?

Yes, whole buildings at a time. We coordinate with strata managers and owners corporations to test plant-room and boundary devices near St Leonards in one visit, certifying each device on the register as we go.

Who lodges the certificate with the water utility?

We do, directly. As licensed backflow plumbers we submit your results through Sydney Water's own system, so the record sits with the utility and you never chase paperwork yourself.

How much does a backflow test cost?

Nothing to find out. The call out is $0 and you receive a fixed written price before testing begins, covering the inspection, the test and the lodgement, with nothing added afterwards.
