We've been in the same house with the same toilet for 25 years. In all those
years we didn't have it overflow a single time until a few weeks ago. At that
time it clogged & overflowed. Since then it's clogged 3 more times, overflowing
2 of those times. The first 3 times a different plumber from the same firm has
used an auger until he says the line is cleared, and the toilet flushes ok many
times until the next clog. Now we've got to get it fixed for a 4th time.
We don't have anybody throwing stuff into the toilet, which shouldn't be there.
The toilet is off the master bedroom. The only other toilet is on the other
side of a wall. We can see where the drain pipes hit the main drain pipes in
the garage. Essentially it's a straight short drop from the top level of a
split level into the garage. Nothing else has had any problems, so presumably
the problem is in the short length of drain pipe or the toilet itself.
Somebody suggested Roto-Rooter; but this isn't a clog in the main line, and
they would seem like overkill ... but I've never used them, so I can't be sure.
Any suggestions as to what could be causing the problem & a solution?
Thanks for your help!
