When you live in a unit, townhouse, or apartment, you share more than a wall. You also share pipes, drains, roofs, and balconies. So when one of them fails, it can hurt many homes at once.
In this guide, our Healesville plumbers explain the five most common plumbing problems in body corporate properties. You will learn the warning signs, why each problem happens, and what to do about it. It is written for owners, committee members, and property managers across the Yarra Valley.
The short answer
- Leaking balconies and failed waterproofing
- Blocked shared drains
- Roof, gutter, and downpipe leaks
- Hidden leaks and burst pipes in shared pipework
- Water pooling around the building
Hydrotight Solutions is a licensed plumbing and drainage business based in Healesville. We have more than 25 years of experience fixing shared plumbing problems for owners corporations, strata managers, and property owners. Most of the callouts we see could have been smaller, cheaper jobs if someone had spotted the signs early.
Who looks after what? In Victoria, the owners corporation (often called the body corporate) usually looks after common property, like shared pipes, roofs, and outside drains. Lot owners usually look after the plumbing inside their own unit. Every building is a little different, so check your owners corporation rules or ask your manager if you are not sure.
1Leaking balconies and failed waterproofing
Balconies take a beating. They face rain, hot sun, and foot traffic every day. Over time, the waterproof layer under the tiles can crack, lift, or wear thin. Water then slips into the slab and walls, and it often shows up in the unit below.
Warning signs
- Stains or damp patches on the ceiling under a balcony
- Bubbling or peeling paint
- A musty smell or mould
- White powder on walls or tiles
- Water that pools instead of draining away
Painting over a stain does not fix a leak. A proper repair finds the source first, then removes the failed layers and installs a new waterproof membrane. Our team offers balcony leak repairs and leak detection for shared buildings, so the real cause is found before any work starts.
2Blocked shared drains
In a body corporate property, many homes often feed into the same main drain. That means one problem can stop the whole line. Grease, wipes, hair, and tree roots are the usual culprits. Older clay pipes can also crack or shift, which gives roots an easy way in.
Warning signs
- Slow drains in more than one unit
- Gurgling sounds from sinks or toilets
- Bad smells near drains or in the car park
- Water backing up at ground level
A quick clear may help for a while, but repeat blockages usually mean something deeper is wrong. A camera inspection shows what is happening inside the pipe. From there, a plumber can clear it, patch a damaged section, or replace the line. If your building keeps having this issue, our drainage plumbing service is a good place to start.
3Roof, gutter, and downpipe leaks
Leaves from the many trees around the Yarra Valley block gutters and downpipes fast. When water cannot escape, it spills over the edge or backs up under the roof sheets. Box gutters and roof valleys are the worst spots, because they carry a lot of water in one place.
Warning signs
- Water stains on top-floor ceilings
- Water spilling over gutters in heavy rain
- Rusty, sagging, or loose gutters
- Overflow at the base of a downpipe
Cleaning gutters before winter helps a lot. Rusted sections, worn flashings, and poor falls need a proper repair, though. Our roof plumbing services cover gutters, downpipes, flashings, and box gutters, which helps protect the building from water damage.
4Hidden leaks and burst pipes in shared pipework
Many shared pipes run inside walls, ceilings, and concrete slabs. You cannot see them, so a small leak can run for months. Ageing pipes, weak joins, and pipes exposed to cold snaps can all fail. The damage often spreads to other units before anyone notices.
Warning signs
- A water bill for the whole complex that jumps for no clear reason
- Low water pressure in several units
- Damp patches or warm spots on floors and walls
- The sound of running water when everything is off
Modern leak detection can often pinpoint the problem without breaking open walls. That saves money, and it means less mess for residents. If a pipe bursts, turn off the water to that section if you can do so safely, then call a plumber straight away.
5Water pooling around the building
A lot of Yarra Valley properties sit on sloping land. Rain runs downhill, and it can collect near walls, car parks, and basements. Without good surface and subsoil drainage, that water soaks into the foundations. Over time it can cause damp walls, cracked paths, and slippery driveways.
Warning signs
- A wet or damp car park after rain
- Damp walls on the ground floor
- Soggy ground near the building
- Cracks in paths or paving
The fix is usually a mix of subsoil drains, channel drains, and correct ground levels so water moves away from the building. It is much cheaper to plan this early than to repair foundation damage later.

How to stop these problems before they start
Most body corporate plumbing problems grow slowly. The good news is that a simple routine catches many of them early:
- Book a yearly plumbing inspection of common areas
- Clean gutters and downpipes before winter
- Get a camera check of main drains every few years, or sooner in older buildings
- Ask residents to report leaks, smells, and slow drains quickly
- Keep a simple log of repairs so patterns are easy to spot

Frequently asked questions
Who pays for plumbing repairs in a body corporate property?
It depends on where the problem is. The owners corporation usually pays for repairs to common property, like shared drains, roofs, and outside pipes. Lot owners usually pay for plumbing inside their own unit. Check your owners corporation rules or ask your manager for the details.
How often should a body corporate plumbing inspection happen?
Once a year is a good starting point for most buildings. Older buildings, or buildings with past leaks, may need checks more often. A yearly check is usually far cheaper than an emergency repair.
Can a plumber find a leak without breaking open walls?
In many cases, yes. Modern leak detection methods can often pinpoint where water is escaping before any cutting or digging begins. That keeps repair costs and disruption to residents lower.
