Strata plumbing maintenance: a real annual program

If you're on a strata committee in Sydney's Eastern Suburbs, you already know plumbing problems don't announce themselves politely. A pipe weeps for six months, then a unit owner texts the building manager at 11pm because water is running down their bedroom wall. By the time anyone calls a plumber, the job is bigger and the levy is harder to justify.

A proper strata plumbing maintenance program is meant to prevent exactly that. Not paperwork for paperwork's sake. Not a quick walk-through that ticks a box. A real annual program finds the problems before they become claims, and gives the committee a clear written record of the building's plumbing health from year to year. Here's what one should actually involve, and how to tell whether the contractor your building is using is doing the work or just collecting a callout fee.

What a real annual program covers

Strata plumbing maintenance programs in Sydney vary wildly, and the price quoted is rarely a useful guide to what you're getting. A proper annual visit in a typical Eastern Suburbs apartment block should cover, at minimum:

• A walk-through of every common area. Car park, fire stairs, lift wells, garbage room, garden taps. Anywhere shared plumbing runs.
• An inspection of the hot water plant. Pressure relief valves, sacrificial anodes on storage tanks, exposed pipework for corrosion. These are the points that fail silently and produce the highest-cost claims.
• A check of the main meter and the building's incoming pressure. Eastern Suburbs supply pressure is high enough to chew through old fittings. If pressure-reducing valves are installed, they need to be tested.
• Drain inspections at the building's accessible points. For older blocks with cast iron or terracotta risers, this is where CCTV inspection earns its money.
• Visual checks of risers and stack vents wherever they're accessible. Stains, salt deposits, and damp patches on cement render are early signs of slow leaks behind walls.
• Tap, mixer, and isolation valve checks in every common-area utility cupboard.

The output of all of this should be a written report the committee can file alongside the strata records, with photographs of any defects and a prioritised list of work needed. The visit is the easy part. The report is the part that earns its fee, because it's the only thing left after the plumber drives away.

Common Eastern Suburbs strata failure points

Norton Plumbing has serviced strata buildings from Bondi to Maroubra to Randwick since 2019, and the same handful of problems come up year after year.

• Coastal copper corrosion. Buildings within a kilometre or two of the beach (so most of Bronte, Coogee, and parts of Bondi) eat through copper pipes from the outside. Salt-laden air attacks the metal where it runs through cement render or sits exposed in plant rooms. A pinhole leak in a hidden riser can run for months before anyone notices.
• Ageing cast iron and terracotta risers. Buildings from the 50s, 60s, and 70s still make up a meaningful share of the area's strata stock. Stack pipes crack at joints, scale up internally, or settle out of true. Roots and grease build up faster than they would in a modern PVC system.
• Hot water plant past its working life. Communal hot water systems sit in plant rooms with limited ventilation, so the corrosion clock starts early. We typically find a few buildings each year where the tank should have been replaced two services ago.
• Backflow prevention that's never been tested. Annual testing on testable backflow devices is required by Sydney Water and the certificates expire. Owners corporations are penalised for missed lodgements, so a good plumber tracks this calendar without being prompted.

None of these are exotic problems. They show up in nearly every committee building above a certain age, and they share a common feature: the worst damage happens between visits. Pinholes weep. Pressure relief valves seize. Backflow lodgements lapse. A proper annual program is built around catching exactly these slow failures before someone texts the building manager at 11pm. What separates a real program from a tick-the-box visit is whether the contractor goes looking for these failure modes before they show up on a complaint from a unit owner. The plumber who only inspects what's already broken is, by definition, working too late.

The reporting your committee should receive

After every annual visit, the committee should get a single written document. At a minimum it should include:

• The date of inspection and the licensed plumber's name and licence number.
• A list of what was inspected, room by room and system by system.
• Photographs of any defects or wear, with location notes the building manager can follow.
• A prioritised list of work, separated into urgent, before next inspection, and monitor.
• Backflow test certificates and any other compliance documents, with their renewal dates.
• An estimate, in writing, for any recommended remedial work over a reasonable threshold, so the committee can budget without surprises.

The point of all this isn't bureaucracy. A strata building's plumbing health is institutional knowledge that has to outlast individual committee members and individual plumbers. A clear annual record makes it possible for next year's committee to read last year's report and understand what they're looking at, what was deferred, and why.

If the report fits on one page and reads no issues found year after year, the inspection isn't being done.

Red flags your current plumber isn't doing the job

Owners corporations rarely change plumbers until something goes wrong, and by then the cost is already locked in. A few signs your strata plumbing maintenance program isn't what you're paying for:

• No written report after the annual visit, only an invoice.
• The plumber never asks about access to the plant room, hot water enclosures, or rooftop fittings.
• Backflow certificates show up late, or never.
• Repeat callouts for the same unit, the same wall, or the same stack with no investigation into the underlying cause.
• The same dollar figure quoted every year regardless of building age, building size, or what was found last time.
• No CCTV inspection on a building old enough to have terracotta or cast iron drainage.

If a couple of these sound familiar, it's worth asking another licensed strata plumber to walk the building before the next service is due. A second opinion costs less than the next emergency callout. The gap between a real maintenance program and a tick-the-box version is often invisible at quoting time. It shows up in the third or fourth year, when buildings on a real program are running flat budgets while buildings without one are scrambling for emergency special levies.
