Kitchen Sink help, sewer water coming from under the cabinets.

Stupid Slip-joints are usually the culprit or main leak points, they should be outlawed and should've never been allowed in any building. However, these will only, normally, leak if there is a blockage further within the system and leak as the water backs-up toward the sink. Have a Plumber in to clear the clog and to replace your Drain-Pipe Assembly with a proper and solid assembly.
