    Going from a garbage disposal to just a drain
    How do you switch from a garbage disposal with a dishwasher to just a plain drain with a dishwasher?

    Hi DP:

    You will need to drop out the disposal, purchase a new sink strainer and a dishwasher tailpiece (can be plastic or brass)... see pictures below. You will also need to deal with the electrical wires in a safe manner.. I recommend a junction box with a cover screwed to the side of base cabinet and capping wires in there).

    The sink strainer gets plumbers putty under the rim of strainer (above sink)... the rubber washer and cardboard washer are used UNDER the sink... RUBBER washer against sink first. I recommend that you get the strainer with basket and 1.5" nut ....not the strainer with a 3.5" nut... ok? The 1.5" nut is a much easier installation!!

    Then the dishwasher tailpiece attaches to the strainer (strainer washer goes on top of the dishwasher tailpiece). Then will need to transition from dishwasher tailpiece to PVC pipe via an 1.5" pvc desanco fitting (see pic.) if PVC and then to pvc ptrap... or by a CLAMP if copper or galvanized pipes or other material!

    Let me know if this all made sense...

    Different areas, different names! In my area we call that a "branch tailpiece".
