Whose side is it on?

In a house a blocked drain is one person's problem. In a city building it is a question before it is a problem.

A blockage inside your own fixtures and branch is yours. One in the common stack or the building's drainage is not, and the difference decides who arranges the work and who pays for it.

The most useful thing you can tell us on the phone is how many apartments are affected. One is a branch problem. Several at once is downstream of all of them, which puts it on the common side and changes who we need to speak to before we even arrive.

Either way we put the finding in writing, so a conversation with building management starts from evidence rather than from two people's opinions.

Local drainage guide

Blocked drains in a city building

The first question is whose

Your own fixtures and the branch serving them, or the common stack and the building's drainage below it. Those are different problems with different people responsible for them.

Getting it wrong wastes a visit and occasionally wastes money, because a plumber called to your apartment cannot repair a common stack and should not try.

It is usually answerable in five minutes from inside your own apartment, which is what the next few blocks are about.

Count the apartments

One apartment affected is a branch problem, and the branch is generally yours. Several at once, particularly stacked above one another, is downstream of all of them and that is the building's.

So the single most useful thing you can do is ask a neighbour above or below whether they have the same symptom.

It takes one message on a building group and it decides who you should be calling.

Which fixtures, and how the water behaves

A single slow basin is that basin and its trap. Everything in the bathroom misbehaving is the branch. Water rising in a lower apartment when an upper one drains is the stack.

That last one is the clearest signal there is that the problem is common rather than private, and it is worth reporting immediately rather than investigating.

Note what you saw and when. In a building, the record matters more than usual because several people will need to act on it.

Risers and meter rooms are controlled

Anything beyond your own apartment needs somebody who can open common services, and that access is arranged through the building rather than turned up for.

It is not obstruction. Risers carry services for the whole stack and buildings are right to control who opens them.

It does mean a common-property job runs to the building's timetable rather than yours, and knowing that early saves frustration.

Buildings set the hours for disruptive work

Which is reasonable and worth knowing before a date is agreed. Noisy or disruptive work is commonly restricted to weekday business hours in residential towers.

So a job that would be a Saturday morning in a house becomes a weekday in a building, and that has to be planned around rather than discovered.

Ask building management what the rules are at the same time as you ask for access. Both answers come from the same person.

An emergency is different

A genuine overflow affecting apartments is not something to wait on, and buildings have processes for exactly that. Ring building management or the after-hours number immediately.

Stop putting water into the system while you wait. That means no washing machine, no dishwasher, no showers and no kitchen sink, in your apartment and ideally in the ones above.

Everything on a stack shares the same outlet, so a blockage low down is made worse by every litre added anywhere above it.

Wipes, and why they matter more in a tower

The largest single cause of what we clear, and in a building the load on one stack arrives from every apartment connected to it rather than from one household.

Which means one household's habits become several households' problem, and nobody involved has any way of knowing.

It is worth raising as a building matter rather than a plumbing one, because that is where it can actually be addressed.

Kitchen fat on a shared stack

The same arithmetic. Fat from a dozen kitchens cooling onto the same length of pipe accumulates far faster than it would in a house.

It narrows the bore gradually and then collects whatever comes past, which produces a stack that has been getting slower for a year and then blocks.

It responds to jetting rather than cabling, and on a common stack that is generally scheduled maintenance rather than an emergency response.

A finding beats an opinion

Where the outcome depends on a conversation with building management, a written finding is worth considerably more than a verbal account relayed second hand.

So ask for what was found in writing, with the date and the location, and keep it. It is the thing that gets acted on.

Camera footage does the same job more strongly again, and it is what turns a disputed impression into an agreed fact.

What we can and cannot do in a building

Inside your apartment, ordinary work with your permission. On common property, only with the building's authority, and we will tell you that rather than proceed and invoice you for it.

Where the problem turns out to be common, the useful outcome from a visit is a clear written finding you can hand to management.

That is frequently worth the call-out on its own, because it is what moves a building process forward.

Blocked drain questions.

What the Sydney CBD locals ask us before booking a plumber.

Ask us yours Licensed plumbing van covering the Sydney CBD and the surrounding suburbs
Is this my problem or the building's?

That is the first question and it is answered by where the fault sits rather than by whose apartment noticed it. A blockage inside your own fixtures and branch is yours. One in the common stack or the building's drainage is not. We establish which, in writing, so the conversation with management starts from a finding rather than an opinion.

More than one apartment is affected. What does that mean?

That the fault is downstream of all of them, which puts it on the common side. One apartment slow is a branch problem; several at once is the building's. It is the single most useful thing you can tell us on the phone, because it changes who we need to speak to before we arrive.

Do you need building management to attend?

Frequently, yes. Access to risers, meter rooms and common services is controlled, and a job that goes beyond your own apartment needs somebody who can open those. Sorting that while we are on the way is what stops a plumber standing in a lobby.

Can you work whenever, or does the building set the hours?

The building generally sets them for anything disruptive. That is not unreasonable and it is worth knowing before a date is agreed. Emergencies are different and most buildings treat them as such.

The same fixture keeps blocking. Is that the building?

If it is only your fixture and nobody else is affected, usually not. A repeat in one branch is normally something structural or habitual on your side. We will say so plainly rather than letting you take an unwinnable case to management.

Do chemical drain cleaners help?

Rarely, and in a building they are worse than useless: they sit on the obstruction, generate heat, and anything that does move goes into a shared system. Tell us if one has gone down before we open anything.

What does clearing a blocked drain cost in the city?

A standard clear through an existing access point is $150 to $400. A camera inspection is $250 to $450 with the footage handed over. Jetting is $400 to $700. Establishing whether the fault is on your side or the building's, in writing, is included.
