    I am adding a tankless gas water heater. I need to drain condensate but don't have anything nearby except the bathroom behind it which I am redoing.

    I was thinking of doing something like a washer in wall drain box/ stand pipe and air gap it into that, using 1 1/4 drain. a floor drain is more complicated due to the slab. my third option would be to pump it up and over somewhere into the bath ? shower? but don't like that approach either.

    The floor in the bath will be raised (floating floor, over slab) so there is room there to run the drain straight across towards the drains.

    Suggestions?

    Let it drain by gravity if its above grade or you can pump it outdoors. Even dig a dry well to keep it out of site. Dallas never has a too long of a freeze to worry about it freezing over.
