Capped pipe coming out of the wall behind the drain, hot/cold water under kit sink?
There is pipe that is capped, coming through the wall behind the drain and hot/cold water pipes below the kitchen sink. What is this pipe? It leaks slightly whenever I run the dishwasher, which of course is connected to the drain. I don't want to take anything apart when I don't know what it is.
I put a small square container under the pipe and up against the wall to catch the drip. But also notice that the floor of the cabinet is slightly wet.
Thanks for any info.
