Up sh*t creek...

SUCCESS!!! Well, partially anyway. We still have the clog, but I finally got that @$!#&*% cleanout plug out! That diamond grit saw blade worked wonders, and then the chisel did the rest. Funny thing was, I had exposed maybe 25% of the thread when I realized what was left of the plug had finally broken loose and was turning like it should have FOUR DAYS AGO!!! Oh, well. We got the expansion plug in there right now. Eventually we'll probably get a brass or PVC plug as a replacement. Thanks again everyone! Now, about that clog...
