The pan or the drain behind it
Blocked Toilet Auckland
A toilet that will not flush away, or fills to the rim and drains slowly. We work out whether the blockage is in the pan or in the drain outside, and send someone with the right gear for it.
The pan or the drain behind it
A toilet that will not flush away, or fills to the rim and drains slowly. We work out whether the blockage is in the pan or in the drain outside, and send someone with the right gear for it.
A blocked toilet is usually caught in the S-bend moulded into the pan: too much paper, wet wipes, sanitary products or something dropped in. Those blockages clear with a flange plunger or a toilet auger, and our guide on how to unblock a toilet shows how. If the shower, basin or outside gully trap is backing up as well, the blockage is further down, in the drain the toilet shares with them, and a plunger won't reach it. That needs a drainlayer. If wastewater is spilling in the street or next door too, call Watercare first.
Most blocked toilets come down to what was flushed. Wet wipes, including ones labelled flushable, do not break down the way toilet paper does. Sanitary pads, tampons, cotton buds and paper towels catch in the pan's S-bend, and too much paper in one flush can do it on its own. Less often the toilet is fine and the problem is the drain beyond it, or the vent.
Check what else in the house is doing it. If only the toilet is slow and every basin, shower and sink drains normally, the blockage is almost certainly in the pan or the short pipe behind it. If the shower rises when you flush, or several fixtures are slow at once, the blockage is in the drain they share, and that is out of a plunger's reach.
Then go outside and find the gully trap, the grated dish at ground level near the kitchen, bathroom or laundry wall. Kitchen, bathroom and laundry waste runs into it, while the toilet normally connects straight into the drain underground. Both then feed the same private drain out to the public sewer. A toilet that will not clear and a gully that is full or overflowing therefore point to a blockage downstream of where the two join. The wider signs of a blocked drain are worth a look at this point.
| What you notice | Where the blockage probably is | What to do |
|---|---|---|
| Only the toilet, everything else drains fine | The pan's S-bend or the pipe just behind it | Plunge it properly, then try a toilet auger |
| Toilet and shower or bath backing up together | The drain serving the bathroom | Stop using water and call a drainlayer |
| Toilet blocked and the outside gully overflowing | Your private drain, downstream of the house | Call a drainlayer and stop plunging |
| Wastewater in the street, or neighbours affected | Possibly the public sewer | Call Watercare first on (09) 442 2222, press 1 |
| Weak flush and gurgling, nothing seems stuck | Possibly a vent problem | Have the vent checked |
Watercare owns the public wastewater network, and its advice is to call them before a plumber if you have a blocked drain or a wastewater overflow, so they can rule out the public pipe. Everything on your side of the point of supply, the toilet included, is the owner's to maintain. Our guide to who is responsible for a blocked drain shows where that line usually sits.
Stop flushing. A second flush on a blocked toilet only adds another cistern of water to a bowl that cannot empty. Then stop the cistern refilling: turn off the small isolation tap on the pipe feeding the cistern, usually behind or beside the toilet, or lift the cistern lid and hold the float up until the water stops.
Call straight away if it is the only toilet in the house, wastewater is spreading across the floor, or it is coming up through a shower or floor waste. Our emergency drainage callouts run 24/7. If there is another working toilet and nothing is overflowing, booking a normal-hours visit costs less.
In a New Zealand rental the landlord is responsible for repairs, and a blocked toilet is a repair. Tenants must tell the landlord as soon as they know something needs fixing. If the tenant caused the blockage carelessly, for example by flushing wipes, they can be liable, but only up to four weeks' rent or the landlord's insurance excess, whichever is lower. Blockages from roots or a failing pipe are the landlord's cost.
If it is the only toilet and it cannot be used, treat it as urgent. Tenancy Services says a tenant can arrange an urgent repair where the problem is likely to cause injury to people or damage to property, and the landlord must pay them back if the tenant made reasonable attempts to tell them first. Keep the texts, photos and invoice. Landlords should ask for the cause in writing: camera footage settles most arguments about whether it was wipes or a broken pipe. Our page on who pays for a blocked drain in a rental goes through each case.
Call a drainlayer or plumber when a plunger has not shifted it after several proper attempts, when you know a solid object went down, when other fixtures or the gully trap are involved, or when the toilet blocks again within days or weeks. A repeat blockage means something is catching in the pan or the drain, and clearing it again will not change that.
Two things are worth avoiding while you wait. Do not pour chemical drain cleaner into the bowl: it will not dissolve wipes or paper, and it leaves a bowl of corrosive water for whoever plunges it next. And do not push a wire coat hanger into the pan, which scratches the glaze. For slow sinks, basins and showers elsewhere in the house, our guide on how to unblock a drain covers what is safe to try.
On the day
The method depends on where the blockage is. A pan blockage is cleared at the toilet, and a drain blockage from outside, through the gully trap or an inspection point. These are the tools and checks you would see on a typical blocked toilet callout, and who is licensed to use them.
A short hand-cranked cable inside a curved tube with a rubber sleeve, so it reaches through the S-bend without marking the porcelain. It breaks up or hooks out most blockages sitting in the pan.
If an object is jammed in the pan, the toilet may have to come off its connection so the item can be removed from behind. Unfixing a plumbing fixture is licensed plumbing work, not a homeowner job.
When the blockage is in the drain, it is cleared through the gully trap or an inspection point with rods or a powered machine, the same way as any drain unblocking job.
If the toilet keeps blocking, a CCTV drain survey shows whether it is roots, a sag holding waste, a cracked joint or plain build-up. The footage also helps when a landlord and tenant disagree about the cause.
Where the drain is lined with build-up rather than plugged at one point, hydro-jetting scours the pipe wall clean instead of opening a narrow channel through it.
Restricted drainage work is done by PGDB-licensed drainlayers, and plumbing work on fixtures by licensed plumbers. You can check anyone's licence on the PGDB public register.
How it runs
Which fixtures are affected, whether the outside gully is full, what might have gone down and whether it is the only toilet. That tells us whether to send someone for a pan blockage or a drain blockage.
A realistic range on the phone and a firm price on site, agreed before anything is touched.
A toilet auger at the pan for a pan blockage. For a drain blockage, rods, a drain machine or the jetter from the gully trap or an inspection point outside, not through your bathroom.
A test flush, then the other fixtures run to check the whole line. If the toilet has blocked before, a camera goes down so you see what caused it.
Cost
Clearing a toilet blocked in the pan is one of the smaller drainage jobs. The price rises when the blockage turns out to be in the drain, when the pan has to come off, or when a camera is needed to find out why it keeps happening.
| What drives the price | Why it matters |
|---|---|
| Where the blockage is | A blockage in the pan is a short job at the toilet. One in the drain means working from outside, and sometimes the full length of the line. |
| What caused it | Paper clears fast. A wad of wipes takes longer, and a solid object that means lifting the pan takes longer again. |
| Access | A reachable gully trap or inspection point keeps a drain job simple. One under decking or a garden bed adds time. |
| Whether a camera is needed | A first-time paper blockage rarely needs one. A toilet that keeps blocking usually does. |
| Time of day | After-hours and public holiday callouts are charged at a higher rate than a booked weekday visit. |

That is a partial blockage. Water is getting past whatever is in the S-bend or the drain, only slowly. If it is just the toilet, the restriction is usually in the pan, often paper or a wipe, and a flange plunger will normally shift it. If the shower or basin gurgles when you flush, the restriction is in the shared drain, and it tends to get worse rather than better.
Sometimes, if the blockage is only toilet paper. Paper softens in water, and after a few hours the bowl may drain on its own. Wipes, sanitary products, cotton buds and solid objects do not break down, so a toilet blocked by those stays blocked. If it has not cleared after a few hours, or it clears and blocks again soon after, something is still in there.
A partly blocked toilet usually gets worse, because each flush packs more paper and waste in behind the restriction. Leaving it risks an overflow onto the floor, water damage to flooring and the subfloor, and wastewater sitting in the house, which carries bacteria and viruses. If the drain is the problem rather than the pan, other fixtures will start backing up too.
It is if it is the only toilet in the house, if it is overflowing, or if wastewater is coming up through a shower or floor waste. Those justify an after-hours callout. If there is a second working toilet and nothing is overflowing, a booked visit in normal hours costs less and is usually fine.
Generally not. The Plumbers, Gasfitters and Drainlayers Board lists fixing or unfixing a plumbing fixture as work a homeowner cannot do, and a toilet is a plumbing fixture. Homeowners may clear a blocked drain, as long as they do not alter or repair the inspection or vent pipe. Taking the pan off to get an object out is a job for a licensed plumber.
Usually one of three things. Something keeps being flushed that should not be, such as wipes. An object or build-up is partly blocking the pan, so paper catches on it. Or the drain outside has roots, a sag or a cracked joint that slows everything down. A camera run through the drain tells the last two apart, which saves paying for clear after clear.
