speaking of kitchen drains, i have the same problem at my house as well.
we do have a garbage disposal and have used the key to use the "self clean" function on it and have tried every snake & drain chemical there is.
right now i think it is more than a clog, never been this bad before. i am debating weather or not to call roto rooter and use their camera service.
any of you guys have experience with roto rooter? also is it safe to run kitchen sink w/o garbage disposal?
im hoping this is simple that can be easily fixed cause the last thing i want is to tear the wall down to fix the pipe behind the kitchen sink...
