Ok guys. I’m replacing the kitchen sink, but the new one is deeper than the old one. This will put the centerline of the discharge line for garbage disposal at the same height as the centerline of drain line in the wall. Is this going to cause drainage problems after the trap is installed? Should I go to the trouble of relocating the drain line?

Is your p-trap still able to stay in-line with your existing desanco? IF it's still able to hold it's slug, you should be fine...if not, you'll have to drop it...
Yes, the trap will be below the mainline, so it should still be able to hold the slug. I'm more concerned about the lack of slope between the T connection and the drain line. It seems like water might stagnate in there.
Try it out for a few days and see how it drains. It's not the end of the earth to cut into the wall and put a couple slip couplings on and drop the desanco, but if you can get around it....
Thanks Jack! I was thinking of trying the offset drain setup shown in FHB #167 (p. 24). The trap is connected directly to the drain line in the wall, which should allow room for the T connector.
Good Luck Ricky....I wish I could have been of more help...I'm just a lowly part-time plumbing apprentice/full-time remodeling contractor. Write what works for you though. Can't ever have enough information....
