This problem started about 3 years ago. I would get this foul odor while taking a shower. The toilet would not flush right. I called 3 different plumbers to check and fix the problem, but it keeps coming back. The last plumber ran a video thru the main line and used the *auger?* to clear the line. That worked for a year and it was wonderful. But now the horrible smell is back, the toilet is having a hard time just flushing water. Is there anything I can do??? PLEASE HELP MEEEEEEEEEE!
