    My mechanical room has a floor sink with 2" pipe, a trap, and vent. It was installed to be a condensate drain. It goes to the septic.

    I am considering putting a small utility sink in the mechanical room and would like to plumb the utility sink into the floor sink without busting any concrete. I don't think I should put a trap in the utility sink drain line as the trap in the floor sink would serve the utility sink. Is my plan going to be legal?

    Thanks,
    Mike

    Mike, when you say floor sink, do you mean floor drain? There is a difference in a floor sink and a floor drain. If it is a receptor, not a floor drain, I would say it is questionable. The only thing is how far you can run the waste to the receptor. Depending upon which code you follow.

    It is definitely a floor sink about 10" square by 12" deep. I put the sink in myself before we poured the concrete. Putting a utility sink in the mechanical room is an idea that came up later. We are governed by UPC. How far can I run my drain line from the utility sink?

    BTW, don't commercial kitchens have sink drains like this?

    Thanks,
    Mike

    Commercial K.S. or food prep sink can use this application. I can't tell you what the upc say's but what I'm governed by is the following.

    For a L.T. you can't dump into a floorsink. Exp. is you can't dump one fix to another. Would it hurt anything probably not. If you are getting it inspected you should do it right. Your code may say something different.
