    Default Indirect waste lines...

    Hello to all,

    Can someone point me to the section in the 2006 IRC that covers/addresses indirect waste situations (e.g. bar sink drained to nearby floor drain, etc.) and what is or is not allowed?

    Thanks!

    A bar sink is not, should not be, an indirect waste.

    It should be connected into the sanitary drainage system.

    10-4.

    Is there a section of the IRC that addresses this specifically? I was trying to find it, and cannot.

    Maybe a UPC section?
