Plumbing advice for leaking toilet

Our upstairs bathroom has a leak. We've had a plumber in 4 times (and had the ceiling of the room beneath it remediated ...ew) and now it is leaking again. Each plumber tells us there is a clog in the toilet, clears it and leaves. The last one was just 4 days ago. None of the plumbers has mentioned a bigger issue but I can't help but wonder if there is a problem with the pipes or maybe something bigger than just a clog. I'm a couple thousand dollars in - the remediation was pricey - and it's still not repaired so seeking input. 


Are you sure the leak is coming from the toilet?

When the ceiling of the room below was removed, did anyone try leaving it open for a while and testing pipes to determine if any of them were a problem?

Could the leak be coming from the roof?


Just clearing a clog isn't going to fix a leak. Sounds like maybe the wax seal is shot. The next plumber should lift the toilet and see what is going on there.


I was told by my plumber that the wax seals are only good for about 10 years. I hadn’t been aware of that. (Until they caused a leak through to the kitchen ceiling, unfortunately…)

 your plumber is wrong. maybe his seals only last 10 years because he's not doing it right.


Could it be the fill valve that has a 10-year “shelf life”? Maybe I’m remembering the wrong repair.
