Question kitchen drain question...

I have the kitchen sink drain currently running straight through the other cabinets making them a little useless. The drain exists through a dividing block wall to the unit next door, so I cannot change the drain exit location.
Would there be any issues with running the pipe down under the cabinets (behind the kickboards) and back up to the exit location? I've attached a sketch of what I am proposing.
Thank you.

Without the slope from the sink to the wall you will experience a lot of clogged pipes especially since this is a kitchen sink. Think about how much waste gets put down the sink and it will just sit in the low spot you have created.

If you do, add a clean out under the sink since you will be visiting it on a pretty regular basis.

Ok. Maybe I'll just live with the lack of cabinet space. Thank you.

The pipe should not be in the way and be barely visible. Pipes through cabinets are somewhat common with sinks under a window.
If the pipe is in the middle of the cabinet, come out of the wall with a 45 elbow pointed towards back of cabinets. Run your pipe along the back using another 45 and go straight into the sink base cabinet.
In the sink base, use another 45 to connect your trap to the disposal if you have one.

Wouldn't your proposed routing create one very large trap? Actually Brian is right on the mark with his suggestion.

Agreed with the others, what you've proposed is against code and will certainly cause clogging and drain flow issues. Brian's solution is your best bet!
