New Kitchen Sink Installation (drain help)

steelcfoAugust 30, 2011

Currently we have a double bowl sink that we are changing to a single bowl sink in the kitchen. The current set up uses two separate drain lines that feed together in the basement. Each drain line has its own P trap. One drain of the sink has a garbage disposal. The dishwasher drains into the drain line that does not have the GD (above the P trap).

With the new single bowl sink, I am wondering what I should do (or what is required) with the second drain line. Can I cap the drain line above where the DW hooks in to the line, so the DW would now have its own dedicated drain line? I will be hooking the new GD to the other drain line that currently uses the existing GD. Or, do I connect the DW drain into the same single line that will have the sink drain/GD and remove the P trap of the second line and cap that drain line at the wall?

Thanks for your help.

Connect the dishwasher drain line to the D.W. input port on the disposal, then you can cut & cap the extra line.
