New 1.6 gallon flush toilets
Some of the older 1.6 gallon per flush commodes were very bad about stopping up. You said she olnly flushed liquid down the commode. Well that was part of the problem with the older commodes... the flush before hers might be the one that stopped up the toilet but her flush was the one that overflowed and made the mess. Speaking of overflowing, if your commode is a new 1.6gallon per flush it should not have made such a mess if it were stopped up, and maybe should not have even ran over the rim of the commode. Try the auger again, they are sometimes hard to get around the trap of the commode.
Toilet clog for no reason
I experienced similar mysteries for quite some time. I started to research the Internet (hence I found this site). It appears there are a lot of issues with the 6Gal toilet. There is a MaP (Maximum Performance) report done on all commercially available toilets. I have since replaced my American Standard Cadet which was rated very poorly. Sometimes even a miss placed toilet paper after a #1 will clog the toilet. You can Google on "toilet performance" to find the report.
Mystery toilet clog... the saga continues
Hi guys,
Thanks for all the help. I think I am going to have to get a new bowl indeed. I pulled it from the floor (thanks for the 'sponge out the water' tip Tom, this kept it from getting messy at all). I tried to fish from the bottom with a coat hanger for a while, but no luck. I put the auger in backwards, with the toilet flipped upside down and made many attempts, but still nothing came out. It is very difficult to get past the bend in the trap with the auger (which must be where the object is stuck).
I then took the bowl outside and rested it on two cinder blocks so the hole on the bottom was unobstructed and I threw a double handful of TP in and dumped in a bucket of water, it went right through, so I did it again with more TP and it went through fine! I have the same model toilet in the other bathroom and it performs fine every flush, but under the house, you can see that the drain from that toilet goes straight down for a foot or more and then makes about a 135 deg. Turn to the main drain. I noticed when I took it off the floor, the drain goes down maybe 4 inches, then there is a sharp turn in the drain (nearly 90 deg. Turn). I wonder if it is having a hard time making this turn. Could this be a factor? Does it indicate there's a clog in the drain pipe leaving that toilet? I think I might try to snake the drain from that toilet to the main line just to be sure nothings in there, then reseat the old bowl for testing, if the problem persists, I guess I'll get a new bowl. And when I do, I'm breaking open the old one to see what my prize is!
