Just had granite countertops installed today with a new undermount sink, and now it appears my garbage disposal may be too low for the drain coming out of the wall. Does it look like I need to move my "tee" in the wall lower? Currently the bottom of the disposal discharge is 13 inches above the cabinet floor.
(BTW, I know that there is no purple primer on the PVC pipes...it was like that when I bought the house. Honest!)
Thanks in advance.
