I don't think my garbage disposal is grinding up the food enough. Twice in 1 month I have had clogs in the sink. My sink is split so the left is the disposal and the right in the regular plain old drain. The clog is in the pipe that connects to the left drain to the main drain. I take the pipe apart and pull out food that isn't really ground up. I'm not putting stuff down there that shouldn't be down there, just lettuce, cucumber skins, etc. No bones or anything like that. When I had the pipe taken apart, I made sure there wasn't any buildup inside the pipe, it was just food that clogged things up. How can I improve the grinding of the disposal OR how do I prevent future clogs?
