Step by Step

Do this before anything else

A blocked toilet is a mess but it is rarely a disaster, as long as you stop it getting worse. Before you reach for the phone, do these three things.

1
Stop flushingEvery flush sends several more litres into a bowl that cannot drain. One extra flush is how a blocked toilet turns into a flooded bathroom.
2
Turn off the cistern tapIt is the small tap on the wall or floor beside the toilet, on the pipe feeding the cistern. Turn it clockwise. If the cistern is running or the float has stuck, this stops it.
3
Plunge properlyUse a flange plunger, the kind with a rubber lip that fits inside the outlet, not the flat sink type. Make sure there is enough water to cover the cup, push down slowly to seal, then pull up sharply. It is the pull that shifts the blockage, not the push. Ten or fifteen strokes, then check whether the level drops. Do not pour chemical drain cleaner into a toilet: it rarely works on this kind of blockage and it makes the bowl dangerous for whoever has to clear it next.
Step by Step

What actually blocks a toilet

After twenty years of clearing them across Sydney, the list of culprits is short and very predictable.

1
"Flushable" wipesThe single biggest cause. They do not break down like paper, they snag on any rough joint, and they bind with hair and grease into a plug that grows with every flush.
2
Sanitary items, cotton buds and dental flossNone of these belong in a toilet. Floss in particular wraps around other debris and holds it in place.
3
Too much paper at onceCommon with young kids, and with low-flush cisterns that do not have the volume to push a large wad through the trap.
4
Toys, deodorant caps and freshener cagesA solid object lodged in the S-bend lets nothing past. A plunger will not fix these; they usually need to be pulled back out, sometimes by lifting the pan.
5
Tree roots in the sewerThe blockage is not in the toilet at all. It is further down the line, and the toilet is simply the lowest fixture in the house, so it is where the problem shows first.

Toilet problem or sewer problem? How to tell

This is the question that decides how the job goes, and you can usually answer it yourself before we arrive.

If only the toilet is affected, the shower and basin drain normally, and the blockage arrived suddenly, it is almost certainly in the pan or the S-bend. That is a quick clear, from $69, and we are usually done within the hour.

If the shower or floor waste is also slow, water gurgles in one fixture when you use another, or dirty water rises in the shower when the toilet is flushed, the blockage is in the sewer line beyond the toilet. That is a drain job. We clear it with a jet blaster or electric eel from the overflow gully outside and run a CCTV camera through to find the cause, usually roots or a broken joint. Everything about how we handle that is on our blocked drains page.

A toilet that blocks repeatedly under normal use, or a cistern that no longer flushes with any force, is often a worn or badly installed toilet rather than a blocked one. We repair and replace pans, cisterns and inlet valves as part of our toilet and tap repairs service.

Good to Know

Sewage overflow is a health issue, not just a mess

Water that has come back up out of a toilet or shower is raw sewage. It carries the bacteria and viruses behind gastro and worse, and it soaks into grout, carpet and skirting boards where it keeps doing so. Keep children and pets out of the room, do not track it through the house, and wear gloves if you have to touch anything. Once we have cleared the line, wash hard surfaces with hot water and disinfectant. Carpet or underlay that has soaked up sewage generally needs replacing rather than cleaning.

If sewage is coming out at the outdoor gully rather than inside, that is the system doing its job. The gully is designed as the first point of release so the overflow happens in the yard, not the bathroom. It still needs clearing today, before the next flush pushes it further.

FAQs

Blocked Toilet Sydney FAQs

How much does it cost to unblock a toilet?
From $69 with $0 call-out. The plumber confirms a fixed price on site before starting. If the blockage turns out to be in the sewer line rather than the toilet, you get a separate fixed quote for that before any further work.
Can I use caustic soda or a chemical drain cleaner?
Please do not. They rarely shift a toilet blockage, they can damage the pan and seals, and they leave a chemical soup in the bowl that is dangerous for the person clearing it. A plunger and a phone call are safer and cheaper.
My toilet blocks every few weeks. Why?
Either something is being flushed that should not be, usually wipes, or there is a problem further down the line such as tree roots or a damaged joint. A CCTV camera inspection finds out which, and we can fix the cause rather than clearing the same blockage again.
Is a blocked toilet an emergency?
If it is the only toilet in the house, or sewage is overflowing inside, yes, and we come out 24/7 with no call-out fee. If you have a second toilet and nothing is overflowing, it can usually wait for the first slot in the morning.
Can I still use the shower and the other toilet?
If the blockage is in the toilet itself, yes. If other drains are slow or gurgling, the sewer is blocked and everything you send down will back up somewhere, so use as little water as you can until we arrive.
Will you have to remove the toilet?
Rarely. Most blockages clear with a plunger, a toilet auger or an electric eel through the pan. Lifting the pan is only needed when a solid object is jammed in the S-bend and cannot be pulled back out.
