I own a recent new house built by Lennar with a kitchen-window bump-out. The plumbing for the kitchen sink seems to have taken a strange path. (PIC A+B)
Instead of jutting straight into the wall behind the sink which is centered below the window, it juts horizontally from underneath the sink cabinet heading into the adjacent space meant for the dishwasher, where it intrudes for about 3 inches when doing a 45 degree bend into the wall where apparently it runs horizontally for a few more feet to the vertical drain and vent pipe behind the next cabinet to the right. (dashed lines in PIC C).
As you can imagine, this reduces the space for the dishwasher by about 1.5 - 2 inches, and the dishwasher pushes up against the pipe when attempting to install which isn't ideal (PIC D). I assume there must be some reason the plumber didn't go straight back into the wall behind the kitchen and do a 90 degree bend to travel right - because it seems that would have been the appropriate install as there is plenty of space, and other than going through one or two studs, should have been easy.
So I'm kind of curious why the plumber didn't go straight into the wall behind the kitchen sink and then run horizontally? Is it possible to fix this plumbing other than buying a slimmer dishwasher, or moving cabinets? I assume a plumber would have to rip open the wall behind the kitchen cabinet and dishwasher, drill a few holes horizontally through two studs, and reconnect the pipe more appropriately.

Won’t know till the wall is opened up
Yeah, i think im going to just add some black rubber to the side of dishwasher and call it good. back silcone gasket
