Nobody ever adds up the clearing

Ashfield is a six-pack suburb: the two and three storey red-brick walk-up, six to twelve flats, no lift, made sellable flat by flat by the Strata Titles Act 1967.

That law is why the plumbing decisions here work the way they do. A repair in a large tower is spread across a hundred lots and paid from a sinking fund nobody feels. In a six-pack the same repair is a special levy of a thousand dollars per owner, landing in the post.

So the block does the affordable thing instead. It clears the stack again. Then again next year. Two clears a year at $350 is $7,000 across a decade, which is more than the repair would have cost, and it is spent in pieces small enough that nobody notices.

We are not going to pretend a special levy is easy. What we will do is put both numbers on one page, including the cost of deferring another year, so the committee is choosing between two known figures instead of one affordable option and one frightening one.

Stack cleared more than twice?

Then it is worth knowing what that is costing per decade. A camera and twenty minutes of arithmetic will tell you, and both come with the inspection.

Drains, stacks and money in an Ashfield six-pack

The building shape came from a law

The six-pack exists because the Strata Titles Act 1967 made individual ownership of flats practical, and a six-lot walk-up was what fitted comfortably on a suburban block.

So these buildings went up in very large numbers over a short period, and this suburb has a great many of them.

They share a shape, a vintage and, importantly, a financial structure. That last one is what this page is about.

A repair here divides by six, not sixty

The same job that vanishes into a tower's sinking fund arrives in a six-lot scheme as a special levy that each owner can feel.

So the identical drainage fault is a routine maintenance item in one building and a genuine financial event in another.

That is not a plumbing difference. It is why small schemes make different decisions from large ones, and it deserves to be understood rather than judged.

Most small schemes have no real sinking fund

These are entry-level buildings and levies were usually set as low as the owners could manage. A capital works fund with a real balance in it is the exception.

So when something needs replacing rather than clearing, the money is not there, and the decision becomes a special levy or nothing.

Nothing is the option that requires no meeting, which is how it usually goes.

Which is how the clearing bill gets invisible

Clearing fits inside ordinary levies. Repair does not. So the block pays for a clearance twice a year for a decade and nobody ever adds it up.

Twenty clearances at a few hundred each is a repair nobody decided to buy, spread thin enough that it never appeared on an agenda.

Adding it up is the single most useful thing anybody on a committee can do, and it takes one evening with the invoices.

Staging is often the answer

Where the full job cannot be funded, some of it usually can. The worst section first, the rest next year, each stage a complete repair in its own right.

That is a real option with lining and not with excavation, and it is covered properly on the relining page.

It turns an impossible number into two possible ones, which is frequently the difference between a decision and another decade of clearances.

Several flats affected means the common line

One flat slow is a branch problem and generally that lot's. Several at once is downstream of all of them, and that is the owners corporation's.

The test is one message to a neighbour, and it decides who should be arranging what.

It matters because a plumber called to your flat cannot repair a common line and should not try.

Once is an event, three times is a defect

A first blockage that clears easily does not need filming. The third in the same year is the line describing itself, and clearing it again is buying the same afternoon.

In a small scheme that threshold is reached quickly, because the same stack serves six households.

Keep the dates. Three dated occurrences is what turns a vague sense into something a committee can act on.

Wipes and kitchen fat, from six households at once

Wipes remain the largest single cause of what we cut out of drains, and on a common stack the load arrives from every flat connected to it.

Kitchen fat is the slower version and the same arithmetic applies. Fat from six kitchens narrows a line considerably faster than fat from one.

That is why common stacks block more often than a house of the same age, and it is nobody in particular's fault.

Old pipework narrows from the inside

Original stacks in buildings of this era are frequently cast iron, which corrodes internally and loses bore over decades with nothing visible from outside.

So the line is not only accumulating material. It has less room for it than it started with, and both effects compound.

That is what a camera shows, and it is the difference between a blockage and a building with a drainage problem.

What the footage settles

Whether there is a defect, where it is, what condition the stack is in, and what repair it needs. All of it in one pass, and the file is yours.

For a small scheme that recording is the thing that makes a decision possible at a meeting, because a committee acts on documents rather than on accounts of what a plumber said.

Ask for the file rather than a viewing, and ask for it whatever it shows.

What blocked drain work costs in Ashfield

Quoted at a fixed price before anyone starts, because that is the only kind of number a committee can approve. These are indicative 2026 ranges.

01

Clear a drain in one flat $150 – $400

Through an existing access point, cleared and flow tested before we leave.

02

Shared stack clearing $250 – $550

Common-area access, with the flat below protected while we work.

03

Camera inspection $250 – $450

Footage handed over. What settles whether this is habits or the pipe.

04

Jetting a stubborn line $400 – $700

Roots and hardened build-up in old pipework take longer than a soft blockage.

05

Costed options for the committee included

Clearing per year against repair once, plus what deferring a year does to both.

How a blocked drain call-out runs.

Step 01
Booking a blocked drain call-out in Ashfield

We ask about the block

How many flats, whether there is a manager, and how often this has happened. That shapes what we hand over at the end.

Step 02
Clearing a shared stack in an Ashfield walk-up

Cleared and flow tested

Through the existing access point, then run properly to confirm it is genuinely clear rather than just moving.

Step 03
Camera inspection of a shared stack in Ashfield

Camera down on a repeat

If this keeps happening we film it, because the committee needs to see the pipe rather than hear about it.

Step 04
Handing costed drain options to an Ashfield owners corporation

Numbers for the meeting

Clearing per year against repair once, staged options, and the cost of waiting. In writing.

What Ashfield locals ask us before booking a plumber.

Ask us yours Licensed plumbing van covering Ashfield and the surrounding suburbs
Our stack gets cleared every year. Is that normal?

It is common, and it is usually a funding decision rather than a plumbing one. Clearing is affordable out of ordinary levies. Repairing is a special levy that six owners have to agree to. So the block keeps paying for clearing because that is the bill it can absorb, and nobody ever adds up what a decade of it comes to. Two clears a year at $350 is $7,000 over ten years, which is comfortably more than most repairs would have been.

How do we work out whether to keep clearing or fix it?

With numbers rather than opinions. We put a camera down and record the actual condition, then set out what clearing costs per year at the current rate, what the repair costs once, and what happens to both figures if the decision is deferred another year. That is a comparison a committee can look at and vote on. Without it the meeting has one affordable option and one frightening one, and it will pick the affordable one every time.

Our block has no strata manager. Who organises this?

In practice, we do a fair amount of it, and that is normal in a scheme this size. There will be no plans on file, no maintenance history, and often no shared knowledge of where the isolation valves are. We establish what is actually there, film it, and hand over a written scope with a figure. Six owners can act on that. They cannot act on a verbal opinion from whoever attended the last blockage.

Why does it always back up in the ground floor flat?

Because that flat is the lowest opening on a line the whole building uses, so when the stack blocks below the lowest connection the water has to surface somewhere and it surfaces at the bottom. The flat that floods very often contributed nothing to the blockage. Worth saying early, before anybody starts assigning blame at a meeting.

Are 'flushable' wipes actually flushable?

No. They clear the bowl, which is all the label really promises, then fail to break down the way paper does. In a shared stack one flat's habit becomes the whole building's blockage, and the person who finds out is whoever lives at the bottom. In a block with a recurring problem, a note on the noticeboard about wipes does more good than most plumbing.

Do chemical drain cleaners work?

Rarely, and in a shared stack they are worse than useless. They sit against the blockage rather than passing through it, they generate heat, and in old pipework they attack the pipe as readily as the obstruction. They also leave caustic water sitting in a line shared with other people's bathrooms. If someone has poured one down, please say so when you ring.

What does clearing a blocked drain cost in Ashfield?

A clear inside a single flat through an existing access point is $150 to $400. A shared stack, where access is in a common area and the flat below has to be protected, is $250 to $550. A camera inspection is $250 to $450 with the footage handed over. For an owners corporation the written scope and the cost comparison come at no extra charge, because a committee cannot vote on something it has not seen.
