The Body Corporate Plumbing Maintenance Plan: What Every OC Committee Needs Annually

If you sit on an owners corporation committee, you already know the meeting agenda items that never seem to go away. Blocked stack in building 3. Hot water system in apartment 7 — again. Gutters that looked fine in summer and now resemble a mulch farm. Most of these are predictable, which means most of them are preventable. The problem isn't the buildings — it's the absence of a structured maintenance plan that catches things before they become emergency expenses or insurance claims.
This isn't a post for landlords managing individual rentals. Our landlord plumbing checklist covers that ground. This is specifically for OC committee members and strata managers responsible for common property across a multi-lot building or complex — the shared hot water systems, the roof, the common-area drainage, the gas risers. The infrastructure that affects every lot owner's levy when it fails.
Why OC Committees Need a Maintenance Plan (Not Just a Reactive Call List)
Most body corporates run on a reactive model: something fails, a lot owner calls the manager, the manager calls a plumber, the plumber quotes, the committee approves, work gets done. That cycle technically works, but it's expensive and unpredictable. Emergency call-outs cost more. Water damage from failing stack joints or leaking roof penetrations escalates fast and hits the administrative fund hard.
A structured annual maintenance plan does two things. First, it converts unplanned emergency spend into predictable, budgeted maintenance — easier for the committee to plan levies and avoid special levies. Second, it generates documented history that matters at AGMs, with insurers, and when there's a dispute about whether common property was maintained to a reasonable standard.
The Annual Maintenance Calendar — What to Schedule and When
Here's a practical template. Adapt it to your building — a 1970s walk-up in Malvern needs different attention to a newer apartment block in Docklands, but the structure is the same.
Autumn (March–April) — Gutters and Roof Drainage
Before Melbourne's winter rain sets in, gutters and downpipes should be cleared of leaf debris and roof penetrations — vent pipes, flashings, valleys — should be visually inspected. A blocked gutter in August means water pushing back under the fascia, and from there into the building envelope. In older buildings with cast-iron or quad gutters, check for rust and joint separation. Identifying your gutter type is a useful starting point if you're not sure what you're dealing with.
Winter (June–July) — Hot Water System Check
Hot water systems work hardest in winter and fail most visibly then. For OC-managed hot water — central systems or heat pump arrays serving multiple lots — have your plumber check tempering valve settings, pressure relief valve condition, and anode rod condition if it's a storage system. Hot water temperature requirements in Australia apply whether the system is in a single dwelling or common property — and if it's common property, compliance is the OC's call, not the individual lot owner's.
Spring (September–October) — Stack Inspections
For multi-storey buildings with shared drainage stacks, a CCTV drain inspection every two to three years is money well spent. Older buildings — anything pre-1980 — often have cast-iron or clayware stacks that deteriorate from the inside out. You won't know until there's a blockage or a wet patch appears on someone's laundry wall. Annual visual inspection of accessible stack junctions and cleanout access points is a low-cost starting point; a CCTV run every few years confirms what's actually happening in the pipe.
Year-Round (Rolling) — Gas Safety Certificates
If the OC is responsible for a gas riser, meter assembly, or any common-area gas appliance — boiler, gas heater in a common space — Victoria's regulations require periodic servicing by a licensed gas fitter. Both the Residential Tenancies Act and OHS obligations apply depending on building configuration. Don't leave this to lot owners to sort out individually. If it's common property, it's the OC's responsibility. What a licensed gas fitter can and can't do is worth reading if you're not certain about the scope.
What to Ask For in a Plumber's Report (So You Can Use It at the AGM)
A phone call and an invoice doesn't give you much to present at an AGM or to an insurer. When you engage a maintenance plumber for an annual inspection, ask for three things: a written inspection report with condition notes and photographs of anything defective; a separate quote for any recommended work so the committee can assess and approve it through proper process; and confirmation of what was actually serviced — date, what was done, parts replaced.
That documentation protects the OC. If a lot owner later claims common-property drainage hasn't been maintained, you have a dated paper trail. If you need to make an insurance claim following a flood or water damage event, you can demonstrate that routine maintenance was being carried out. Some insurers will ask.
How to Brief a Plumber for Strata Work
Not every maintenance plumber is set up to work efficiently on multi-lot buildings. A few things that make the engagement go smoothly:
Provide a schedule of common property before the visit — so the plumber knows what they're responsible for inspecting versus what falls inside lot boundaries. Arrange access in advance — for apartment buildings, this means coordinating with lot owners or the building manager. A plumber who arrives to find a locked meter room and no key wastes everyone's time and incurs a call-out fee. Agree on scope in writing — "check the plumbing" isn't a scope; "inspect and flush all common-area drainage, check hot water tempering valves, photograph stack access points and note condition" is. Confirm licensing for gas — any gas work on common property must be carried out by a licensed gas fitter in Victoria. Non-negotiable, and worth confirming before the job starts.
If you manage multiple buildings, a regular plumber who already knows your portfolio substantially reduces the briefing overhead each visit. What to look for in a maintenance partner goes into more depth on this.
What to Watch For Between Scheduled Visits
Some things don't wait for the annual inspection. Put a note in your lot-owner communications or brief the building manager to report the following immediately:
Wet patches on common walls or ceilings — almost always a leaking stack joint or water penetration from above. Slow drainage reported across multiple units simultaneously — if several lots report slow drains at the same time, the blockage is in the common stack, not an individual lot. Discolouration around hot water outlets in common areas — can indicate a failing system or sediment buildup. Yellow or flickering pilot flames on common-area gas appliances — this requires immediate service, not monitoring. Gutter overflow during moderate rainfall — if gutters overflow in light rain, the downpipe is blocked; heavy rain is expected to overwhelm old systems, but moderate rain shouldn't.
What Happens When You Book Us
1. You contact us — by phone, online booking, or email. We'll ask a few questions: building type, approximate age, number of lots, and what you want inspected or serviced.
2. We confirm scope and timing — in writing, so there are no surprises on the day or on the invoice.
3. We attend and carry out the work — we work through the agreed scope, flag anything that needs attention, and photograph relevant items.
4. You receive a written report — within a few business days of the visit, in a format suitable for committee review and AGM documentation.
5. We quote any follow-up work separately — the committee can go through proper approval process before any additional spend is committed.
What We Don't Do
Plumb Melbourne focuses on residential maintenance plumbing, gas appliance servicing, roof and gutter repairs, and drain clearing. We don't do hydronic heating systems or air conditioning. If your building has hydronic or HVAC that needs service, we'll tell you upfront rather than pretend it's in our scope.
Servicing Buildings Across South-Eastern Melbourne
We work regularly with strata managers and OC committees in South Yarra, Toorak, Prahran, Windsor, Armadale, St Kilda East, Malvern, Glen Iris, Mont Albert, McKinnon, Black Rock, Chadstone, Moorabbin, Balwyn, and Docklands.
