Cleared the same day where we can, then filmed, because on drainage this young a repeat blockage is a clue about how it was laid rather than a sign of wear.

In an older suburb a recurring blockage usually has a straightforward story behind it. Earthenware cracks, steel corrodes, joints open, roots find them. Decades of service, and eventually the pipe has had enough.
That story does not apply out here, and pretending it does costs people money. The drainage under these estates is modern PVC. It does not corrode, it does not open at the joints the way old collar joints did, and root ingress is a fraction of what it is in the inner suburbs.
So when a young line blocks repeatedly, it is telling you about how it was put in rather than how it has aged. Not enough fall on a section, a bend where material stalls, debris left behind at construction. Those are real and they are common, and none of them get better on their own.
The good news is that they are also specific. A camera turns a recurring mystery into a location and a cause, and a location and a cause can be quoted. On a line still inside a builder's warranty, the footage is also the only thing anyone will act on.
Then say so when you ring, and the camera comes on this visit rather than the next one.
It does not corrode and it does not open at the joints the way older materials did. The pipework under most of this suburb is younger than the people living above it and it has not reached the end of anything.
Which means the standard advice about aged drainage, roots at open joints and pipe at the end of its life does not describe a house here.
So a line that blocks repeatedly on young housing is telling you something else, and this page is about what.
A section without enough grade holds material instead of moving it. Water gets away and solids do not, and what is left sits in the flat spot until it builds enough to stop the line.
Drainage laid at minimum grade works while the ground beneath it stays put. On estates built over engineered fill, the first few years of settlement can take the margin away.
The tell is a line that blocks in the same place, again, for no apparent reason, and clears easily every time. That is a grade fault rather than a blockage.
Mortar, sand, render and offcuts enter open drainage while a house is being built, settle somewhere along the run, and stay there. It is one of the most common causes of a blockage on a young house.
Nobody does it on purpose. Drainage sits open during construction and a great many trades pass over it.
It is also completely visible on camera, which is why filming early on a new house is worth more than filming early on an old one.
A single slow basin is local to that fixture and its trap. Several fixtures, or the lowest one in the house, is the main line out telling you so.
On a wide single-storey house the lowest point is usually a laundry tub, a shower or a floor waste rather than the toilet everybody watches.
Frequency is the number worth keeping. Once is an event. Three times in a year in the same place is a defect describing itself, and on housing this age that is worth chasing properly.
It goes to stormwater rather than to the sewer, and it blocks like anything else. Most houses on these estates have a rainwater tank because the building rules of the day required one.
An overflow that has silted or been blocked by leaf litter puts water beside the tank instead of into the stormwater system, and on new fill that is worth caring about.
It is also the thing nobody has ever looked at, because it does nothing visible until the day it matters.
Sewer and stormwater are separate systems and connecting one to the other is not lawful. Trouble that only appears in heavy rain and clears when it stops is the stormwater side.
On an estate that usually means a pit, a downpipe connection, or the tank overflow above. None of them is the sewer and none of them takes the same equipment.
Saying which one you have when you ring is what gets the right machine to the property first time.
The single largest cause of what we clear, on new estates as much as old suburbs, whatever the packet claims about flushability. They do not break down and they hold everything that follows them.
That matters more here than it looks, because a blockage caused by what went down the drain is not a fault in the drain.
The camera is what separates the two, and on a house still inside its builder's warranty that distinction is worth having in writing.
It cools onto the pipe wall, narrows the bore a fraction at a time, and then starts collecting whatever comes past. Nothing happens for a year and then a drain stops.
It responds to jetting rather than to a cable, because there is nothing solid to catch, and it comes back if the habit does.
That is the honest thing to say about it rather than selling a schedule of preventative visits.
On a house still inside its builder's warranty period, the order is document first, repair second. A defect that has already been cleared is very hard to raise, because the evidence went down the drain with it.
Photograph what you can, note the date, and get the line filmed before it is cleared where that is practical. Where it is not, get it filmed straight afterwards.
We are plumbers rather than lawyers and we will not advise you on your rights. We will document what we find well enough that somebody else can.
Whether there is debris in the line, whether the fall is right, whether the jointing was done properly, and whether anything has been crushed. All four in one pass.
The footage is yours whatever it shows, and on young housing a clean result is a genuinely likely outcome and a useful one.
It also gives you a baseline. If the same line misbehaves in five years, comparing the two recordings answers the question immediately.
Fixed price agreed before anything starts. These are indicative 2026 ranges.
Through an existing access point where the property has one.
The recording is yours, and on a house under warranty it is the thing that gets acted on.
For what a cable alone will not move.
Position and depth marked, so nobody works from a guess.
What was found, what caused it, and whether it is a fall or an obstruction.
Which fixture, and how many times it has done this. On young drainage that answer changes the whole visit.
Through an access point where one exists, with the least disruptive method that will actually work.
So a recurring blockage becomes a location and a cause rather than an annual appointment.
Fall, obstruction, or nothing wrong at all. In writing, with the footage, so you can take it further if the house is still under warranty.
Ring and a licensed plumber picks up. We can be moving toward you while you are still talking.
Call 1300 381 569Because age is not the cause. Modern PVC does not corrode or crack the way earthenware and steel did, so a young line that blocks repeatedly is usually telling you something about how it was laid rather than about how it has aged. Insufficient fall, a bend that material stalls in, or debris left in the line at construction are the usual answers.
Frequently it is cheaper than people fear, because it is a defined problem in a defined spot rather than a whole run that has run out of life. The camera turns it from a mystery into a location, and a location is quotable.
Wipes, comfortably ahead of everything else, whatever the packet claims. Then fat and hair. Roots are much less of an issue in modern PVC than in older suburbs, though established planting on the older parts of the area can still find a joint.
It is a different line and it is worth saying so. A rainwater tank overflow is plumbed to stormwater rather than to the sewer, and when it blocks the water goes where it can, which is usually somewhere you would rather it did not. It is a straightforward clear.
On the second occurrence, yes. Once is an event. Twice in the same fixture on a young line is information, and the footage is what turns that into a fix instead of an annual call-out.
Yes, and keep it. It is the evidence behind whatever gets recommended, and it settles any argument later, including with a builder if the line is still under warranty.
Clearing a blocked drain is $150 to $400. A camera inspection is $250 to $450. Jetting is $400 to $700. Locating and marking a defect is $250 to $500, with written findings included.
Tell us which fixture, and how many times it has happened. On drainage this young, recurrence is the useful detail rather than the age of the house.
Cleared, filmed where it is warranted, and written up so you can use it.
