Blocked Drains Across a Strata Scheme
A blocked shared drain stops being one owner's problem the moment several lots back up at once. A strata scheme is a property split into lots and shared common property. The owners corporation, formerly the body corporate, includes every owner in the scheme. Every owner automatically belongs. Strata properties include apartments, townhouses, villas and many duplexes, and all follow the strata repair and maintenance rules. Our commercial drain services page covers strata plumbing and body corporate drains among the property types it serves.
Stacks and Inspection Openings
The sewer stack is the vertical pipe carrying the building's sewage down, also called the soil stack. AS/NZS 3500.2, the standard for sanitary plumbing and drainage, requires an inspection opening at the base of every stack. An inspection opening (IO) is access into a pipe for clearing and testing. Audits keep finding these openings sealed inside walls. A stack damaged beyond clearing is a repair job, not a clearing job.
-
Openings at the Base
Inspection openings are required at the base of every stack and at any stack level that needs one. The standard also requires openings in every common discharge pipe at intervals of no more than 30 m. Every junction fitting needs an opening where it connects a discharge pipe to a stack. Every required opening has to stay accessible, which can mean removing an access panel, cover or door.
-
Openings Sealed Behind Tiles
When an inspection opening is sealed behind tiles, the fix is an opening raised to finished surface level with an airtight removable cap. Building Commission NSW audits repeatedly find required items installed within walls with no access panel. Some of these walls are waterproofed, tiled and fire-rated, so access later puts the fire rating and waterproofing at risk and brings remediation costs.
-
Fixtures Below the Stack
Basement fixtures below the sewer stack can take wastewater from upper floors when the sewer surcharges, where those fixtures discharge to a sewage ejector or wet well. A reflux valve keeps sewer surcharge out of basement fixtures by stopping the surcharge before it reaches them.
Common Property or Lot Drains?
No, the fixture doesn't decide who answers for a drain. In most cases, the pipe's position decides, according to NSW Fair Trading. The owners corporation looks after boundary wall and under-floor plumbing in most cases, according to NSW Fair Trading's list. The lot owner looks after internal wall and fixture plumbing in most cases, according to the same list. A licensed plumber clears the pipe on either side of the split. Our strata plumbing responsibility nsw guide carries the full NSW rules on common property drains, the strata plan and by-laws included. NSW Fair Trading's strata repairs and maintenance page sets out the responsibility split and the repairs process.
-
Boundary Walls and Floors
Boundary wall and under-floor plumbing sits with the owners corporation in most cases, according to NSW Fair Trading's list. Common property is generally any area all residents use or anything of structural importance, and pipes are among the examples. Each scheme classifies different areas.
-
Plumbing Inside Your Unit
Plumbing in internal walls and fixtures sits with the lot owner in most cases, according to the same list. Baths, toilets, sinks and showers count as the lot owner's fixtures.
-
The Strata Plan Decides
Where the split is unclear, the strata plan and by-laws decide. A copy can come from the owners corporation, the committee secretary, the strata manager or the agent, or an NSW Land Registry Services (LRS) approved information broker. A scheme can adopt the common property memorandum by special resolution where its by-laws define no common property. The memorandum is the NSW Government's standard common property list. The Strata Community Association NSW (SCA) publishes the Who's Responsible Guide, a list of items generally considered common property. The guide recommends using it with the strata plan and by-laws in more complex cases.
After-Hours Blockages in Strata Buildings
A blocked shared sewer line at night is still an emergency repair, and the rules treat it as one. We are open 24 hours for same-day emergency service. An owner notifies the strata manager where possible. The strata management company's website lists its emergency tradespeople. Where there is no list, the owner can choose which strata emergency plumber to hire. A blocked shared line does not wait for a meeting.
-
Getting the Cost Back
The owners corporation may refund an owner who pays for an emergency repair. The refund test asks the owner to show the job was the owners corporation's responsibility and that calling the tradesperson was necessary and urgent. Keep photos and the tradesperson's written details to support the claim.
-
Building Manager Access
The building manager looks after common property on site. A building manager is the on-site manager of common property and access. Tradespersons and non-residents get access to common property through the building manager, generally the first contact for contractors on site.

Apartment block sewer and stormwater lines run through common property to serve every lot, so go straight to the job that fits:
How Strata Drain Work Gets Approved
Approving common property work runs four steps. A scheme gets quotes from a licensed and insured supplier and approves the preferred quote. The scheme has the work done, checks the finished work and pays the invoice. From 27 October 2025, NSW Fair Trading has stronger powers to enforce owners corporations' duty to repair and maintain common property. Schemes should routinely hire licensed tradespeople. An owner should always check a tradesperson is licensed before engaging them. In NSW, any plumbing work needs a licence or certificate, whatever the cost and whether it is residential, commercial or industrial.
-
Tell the Strata Manager
Tell the strata manager, or ask the strata committee, about common property work. An owner writes to the secretary or strata manager with clear details of the repair request. The manager coordinates with the committee and owners corporation to get the job approved. An owner can find the strata manager through the NSW Government's online Strata search or from levies paperwork. The owners corporation delegates jobs to the strata manager, also called a strata managing agent, including paying invoices. Tenants contact their landlord or real estate agent first, and our property manager plumber page covers the rental side.
-
Minor Work Without Meetings
Minor common property work doesn't need a meeting: the strata committee, the strata manager or the building manager can manage it. Some jobs should not wait for a meeting. Costly work that the funds can't cover needs a meeting called. Most minor common property repairs can be paid from the administrative fund, according to NSW Fair Trading.
-
Two Quotes Over $30,000
Once the work is valued at $30,000 or more, all schemes need at least two independent quotes, regardless of size, according to NSW Fair Trading's 2026 guidance. The rule does not apply to emergency repairs, with burst or blocked water or sewerage pipes among the examples.
Our Process
We clear a shared strata line in five steps, starting with the camera:
-
Answer the call
Someone real answers the phone at any hour, day or night, and books the visit for the strata manager or lot owner. -
Find the blockage
We inspect the line with the CCTV drain camera before any quote. The footage shows the strata manager and the owners corporation the fault, not a guess. -
Quote before work
The written price reaches you before the work starts, on every job. -
Clear the line
The jet blaster or electric eel clears the blockage from the shared line. -
Prove it on camera
A final camera run shows the shared line clear.
Common Strata Drain Problems We Fix
Strata managers and lot owners can watch for these signs and causes in the shared lines:
- The signs: A wastewater blockage shows four signs: sinks, a bath or toilet emptying slowly; a toilet not flushing properly or overflowed; and gurgling from a toilet or floor drain. The fourth sign is wastewater overflowing from the drain or gully near the outside tap.
- The causes: Unflushable items going down toilets, fats, oils and grease in sinks, tree roots, and stormwater overloading the wastewater network in heavy rain.
- Tree roots: Roots enter small cracks seeking nutrients, keep growing and slow drainage until the pipe can block.
- Who pays: Owners answer for the wastewater pipes up to where they connect to Sydney Water's network. In a strata building that line is common property, so the owners corporation answers for it.
- Sydney Water's pipes: The blockage probably sits in Sydney Water's pipes when wastewater shows up beyond the boundary, for example at a maintenance hole on public land. The other signs are neighbours with the same problem, widespread local flooding, or overflow with no water in use. Sydney Water's wastewater blockages page lists the blockage signs and who pays on each side of the connection.
- Faults line: Sydney Water's faults line, 13 20 90, takes reports 24/7 and Sydney Water sends a crew for faults in its own pipes.
- Safety: For your own safety, keep clear of wastewater overflows until a plumber clears the drain.
- The 3 Ps: Only pee, poo and toilet paper go down the toilet.
- Stormwater rule: Sydney Water's connection rules say rainwater or stormwater must not be allowed to enter the wastewater system.
-
Gurgling Floor Wastes
A gurgling floor waste is a sign of a partial blockage in the shared line, which is the owners corporation's to clear. Gurgling from several fixtures at once points to the shared line, not one lot's fixtures.

Frequently Asked Questions
How Much Does a Strata Plumber Charge per Hour in Sydney?
A Sydney plumber charges $92 to $230 an hour for standard work, with around $140 typical, according to a 2026 Sydney cost guide. We quote drain clears per job, not by the hour. The quote comes in writing before work starts, confirming the price.
Is a Blocked Toilet a Strata Issue?
No, the lot owner clears a blockage in their own pan or internal fixtures. The owners corporation answers for a blockage in the shared stack or the pipe under the floor.
Can Strata Make an Owner Pay for a Blocked Drain?
Yes, the owners corporation repairs the common property pipe first and may recover the cost from the owner whose damage caused it. The owners corporation cannot delay the work where the delay would affect safety or a person's access or use.
Is Jetting Better Than an Electric Eel for Strata Drains?
An electric eel clears a single tough blockage; jetting cleans the whole shared line. The camera decides which the job needs.
