Make your jokes now. I know I am full of sh!t.
Anyway
At one point last year my toilet would not flush & acted as it were plugged, even though it shouldn't be. Even so, I plunged it many times & eventually it flushed fully.
A few months later it did the same thing. I attempted many times to plunge it, even bought and tried a toilet snake to no avail. This time I noticed that when I was plunging that there was a suction noise coming from near the side. The cap on the mount bolt is missing & when I looked I could actually see some water past the nut. When I plunged I could see the water react to the suction. There was no water leaking outside of the toilet, though where the linoleum isn't cut perfect I did notice the subfloor appeared wet.
At that point I called my landlord to inform him of the situation. He wasn't able to make it out that evening, but said he would investigate the following day. Well, wouldn't you know it the toilet flushed on it's own the next time I flushed it before he could even get there to see what it was doing. I had to work the following day, but I left him a note telling him of everything. Unfortunately, he did not see the note. He dug up and checked the septic tank, which was fine, and since the toilet was flushing fine he considered the issue fixed, even though the subfloor was wet.
Anyway, that was almost a year ago & the toilet started doing it again. It started last week and would sometimes flush, and sometimes not. Landlord was called, but hasn't made it out yet. I even started looking at possible fixes online and found nothing that describes my issue. I even put some dish soap down the overflow pipe, as instructed in one video and when I flushed bubbles actually came out of the bolt hole.
I stopped trying at that point and intend on waiting on the landlord. Only thing I can figure at this point is internal crack or an issue with the wax ring. The only thing with that, though, is you would think the issue wouldn't have "fixed itself" twice before.
So if anyone has any tips or advice that I might be able to help my landlord with I would greatly appreciate it.
