Toilet arm clog causing the shower to back up?
(I think) I've tried everything to un-clog this backup. Flush the toilet, water starts coming up the shower drain. The toilet still flushes, but I can see the water in the shower drain rising up again. Started with the old baking soda/vinegar thing down the shower drain, no luck. Went on to snaking the toilet with a closet auger (finally) got it in up to the handle, still no luck. Have been trying to get a 25 FT vinyl snake down the toilet but it's getting stuck somewhere. Got a 50 FT snake down the outside clean-out with no problem. So I need help with either getting the snake through the toilet (it's a Koehler Rialto) or do I have to remove the toilet and go at it there? Please help before tears well up and VERY inappropriate words start coming out!Thank You!RB
