Ok my fellow G body friends. Yesterday my wife while cooking put some broken up egg shells down the garbage disposal. Now i have a backed up kitchen drain. This happened before and i used some drain cleaner and after a few hours it seemed to work. I warned her not to do that again. Well she did it again. We live in a manufactured home so the plumbing is different from a stick house im sure. So now my sink, dishwasher and washing machine can't be used.So i purchased what is supposed to be the number 1 drain cleaner(pic included) and dumped it down the sink and the laundry room sink. Both drains are hooked together. Its been in there about 4 hrs no luck. I have a 20ft snake (not a real one) and ran it down there. No luck. Any suggestions before i call the plumber
