Oh, how dumb! I found an old container half full of yogurt in the back of my fridge. Because I'm a big recycler, I did not toss the whole moldy thing in the trash - I flushed the contents down the toilet. Now it's slowing the toilet. I've flushed & flushed, and I've plunged & plunged, but to no avail. Then I poured white vinegar in and flushed again. So far, no luck.
I can't get a snake through the bends. Any help out there? What might dissolve that clot of mold? With the pros charging $100. Just to appear, I dread calling a plumber.
