I'm in the process of installing a new sink which has deeper basins than the previous sink. Because the basins are deeper the garbage disposal's outlet now sits lower than the outlet pipe into the wall.
My questions are:
1. Is it ok if the disposal outlet is lower than the wall outlet? If not, will I have to tear into the wall to mount a new outlet pipe?
2. If it is ok to leave as is, I'm having trouble finding a set of PVC slip fit pipes that will work. The standard 1-1/2" P Trap kit I picked up has a wall pipe with about a 1" extension to the flange off the bend. I really need something that extends down about 4" off the wall pipe. Does something like this exist? I've been searching around but can't seem to find anything. If it doesn't exist, does someone have any recommendations on what to use?
