Troubleshooting steps/questions:

  • Has this toilet always had this problem, or was there ever anything installed in this location that didn't clog like this? If the toilet has always had this problem then it's likely some issue with the initial installation; the drain pipe diameter may be too small, or there may be insufficient venting which is causing slow drainage in the wall because there's no "air behind water".

  • If it didn't always have this problem, then something has changed. Would that be anything obvious like a remodel, or something more gradual like build-up accumulation? If the toilet was replaced at some point, either as its own job or as part of a larger remodel, then most likely something was done during construction/installation that is causing an obstruction. If not, then mineral or organic build-up is the most likely culprit.

  • From the comments, what DID the plumber do, if he didn't scope the drain, lift the throne, and/or inspect the vent stack from the roof? Anything he did do, besides flush a toilet with nothing but clean water in it, may help to eliminate or diagnose potential problems.

  • Does the toilet always seem to drain slowly, even if it doesn't clog outright? Slow drainage of the bowl in all circumstances would point to an obstruction of the pipe diameter itself, such as an improper flange installation, a defect in the toilet, or blockage in the piping. Fast flow in a "normal" flush, but easy clogging, generally points to a foreign object blocking the pipe in such a way as to trap solids as they go down the drain, but allowing water without any solids to pass by normally.

  • Are there small children in the house? A child could have flushed a pencil, pen or other long, stiff object which is now caught in a turn in the plumbing and is trapping solid matter to form clogs. Scoping the drain will identify this blockage, and a professional snake will clear it (the homeowners'-variety snake with a coiled end won't do anything; you'll need a snake with bladed ends designed to chew into or through solid blockages, which require some knowhow to use without further damaging your drains).

r/Plumbing on Reddit: Trying to figure out why toilet keeps "clogging" but often there's no obvious cause.
June 19, 2021 -

I have a ground floor toilet that clogs every few days. Snaking with a 6 ft snake and/or plunging temporarily fixes the issue.

  • Wife is convinced that it's always tied to someone immediately pooping beforehand.

  • I am not so sure b/c there are a lot of times that it seems to clog and no one has pooped recently / immediately before the clog. Even under these circumstances, snaking and/or plunging seems to temporarily fix the issue.

  • None of the sinks, bathtubs, etc. have clogging issues. Just this one toilet.

Is it possible that the snake isn't really reaching the main clog / constriction? If so, how do I fix this? Longer snake?

Thank you.

Sorry. No photos, but I don't think it would be helpful here.

Why does my toilet always clog? Is it my massive dumps that I'm dropping in the toilet? - Quora
As a result, we have lousy shower head, washing machines that don't clean well, and toilets that clog easily. Toilets manufactured since you were born use half of the water that toilets used to use. Toilet manufacturers jumped through hoops and came up with “new and improved, low water consumption” toilets. And they swear they work well. The truth is that they don’t work well, and they don’t save much water. Instead of one flush, it can take two or three flushes in some cases.

We do eat more meat, less fiber ... time, and we don't clog toilets. Just this one. What makes this one exceptional is that we often have to snake it when it does clog. Just plunging never releases the clog. Is the plumber nuts? Is there something else going on her... More on diy.stackexchange.com

All the toilets in the house clog easily, but plunging clears them quickly. Pipes issue or just bad toilets?
When your house was built, they used the cheapest “builder’s grade” fixtures. And back in the mid 90s, manufacturers still hadn’t perfected low-flow 1.6 gallon flush toilets. (Back then, some Americans would go to Canada to purchase 3.5 gallon flush toilets.) Get yourself a decent new toilet. Price does not correlate to performance, but don’t buy the cheapest. Toto consistently makes very good toilets. The last couple toilets I installed were American Standard Champion models, which are less expensive and they work very well. Niagara Stealth toilets are cool, but replacement parts are harder to find. More on reddit.com

Trying to figure out why toilet keeps "clogging" but often there's no obvious cause.
Could be something floating in the trap. Toys, small Poopouri bottles, those plastic teeth flossers, q tips etc can kind of float and get stuck in the top part of of trap on toilets. If it's within your skill set, I would recommend pulling the toilet and snaking backwards, inspecting the inside of both the toilet and flange pipe. Not a bad time to snake down the flange if you want to take the extra step. More on reddit.com

Toilet keeps getting clogged
Sounds like You have a clog somewhere more than 25ft past that toilet and the gurgling is probably the vent being blocked with it. Best shot to me would probably be just keep snaking it from here and different spots downstairs with a longer line. tip look for a drain tech in particular instead of a plumber. More on reddit.com

Why Your Toilet Keeps Clogging and How to Fix It | HSA
So, what is the number one cause of clogged toilets? It’s typically not just one issue—in fact, there are many. One of the more common reasons a toilet always clogs is due to items that don’t belong down there. These non-flushable items include wipes (even “flushable” ones), paper towels, and feminine hygiene products, which can easily get caught in pipes and lead to repeated blockages.

The first thing I would recommend is to use one of the other 2 toilets that don't clog. For the troublesome toilet, these are some clogging factors:

  • Too much waste. Try multiple flushes or cut down on the amount of paper. Switch to a different brand of paper.
  • A foreign object is in the toilet. Maybe a toothbrush or something that cannot be flushed is clogging the toilet line.
  • Clog in the vent pipe, the plumber should had checked for this but a vent pipe that is clogged will effect plumbing and flush capability.
  • Insufficient flush for the toilet design. Not all toilets flush equally, try replacing the toilet with one with a good flush. Toilets are pretty easy to replace. This may reveal other things as well like maybe the toilet is not seated properly (wax ring issue).

If there are no other clogging issues, then the problem is most likely localized to that one plumbing fixture, but if thre are other issues, then the problem may be further down the line which a plumber should be able to diagnose and fix.

7 Reasons Your Toilet Keeps Clogging
February 2, 2025 - Low-flow toilets reduce unnecessary water usage and lower water bills but are prone to clogging. The problem is more pronounced with older, less efficient, low-flush toilets than with recent designs. Upgrade to a new low-flow toilet. Some models use pressurized air to force a small amount of water down the bowl faster, making them as effective as standard toilets.

If you have an early model, your toilet clogs often because these toilets lack the pressure necessary to push material down the trap and into your drain. When toilets lack flushing pressure, the material tends to be left behind. Over time, this can lead to a toilet clogging repeatedly.

Defined as water with a high content of dissolved calcium and magnesium, hard water leaves mineral deposits on almost everything it touches… including your toilet drain line. Given enough time, the sediment will narrow the pipe openings and restrict water flow. This is yet another cause of toilet clogging. Experienced drain cleaning services can solve the problem.

January 17, 2024 - All drain pipes have something called a trap – a U-shaped bend in the pipe that remains filled with water. That water acts as an important barrier against foul odors that might otherwise waft into a home from the sewer line. Your toilet’s trap is great at getting this job done, but unfortunately, that bend in the pipe also makes a good place for a clog to develop.

It’s a particular problem if tree roots have infiltrated the drainage system or the pipe has broken or is corroding. Usually, when this happens, it won’t just be your toilet that ends up backing up. A clogged sewer line will affect drainage throughout your home, and unfortunately, it’s not a fix you can DIY.
