    Default Foot Vent For Island Sink....Could an inspector be wrong? UPC

    Hey everyone,

    First I'd like to thank everyone who helped me set up my DWV, passed dry fitting inspection first try. Thank you.

    However, I had one fitting that the inspector wants me to change when I glue.

    My foot vent looks just like the first image except I put a clean out on the vent above the floor.

    My question is with the second picture:

    The picture here shows a San Tee being used, however my inspector wants a wye combo there instead. My first reaction at the time, do whatever the inspector says, but now that I'm gluing the combo is adding about 2", dropping the drain below the ceiling in the basement, which I was hoping wouldn't happen.

    Any suggestions? Should I challenge the inspector or just do it like he wants and deal with a drop ceiling?

    Thanks in advance for any help

    There should have been a cleanout on the foot vent, the drawin didn't show that.
    The santee on the vertical should be fine. It's how we plumb them in Seattle.

    The picture shows wye combos on their backs. Those are fine that way too.

    Hey Terry

    Thanks for the reply, Yeah have you ever heard of an inspector asking for a wye combo in place of the santee on the vertical?

    According to the way it is worded in the UPC the fitting should be a wye type (combo). It is up to the local jurisdiction exactly how they want it. Here in Hawaii the inspectors allowed a san tee in that position for many years. However with the influx of a new batch of inspectors they now require it to be a combo exactly as stated in the UPC.

    The UPC Illustrated Training Manual also shows a combination.

    Put a 45, under the floor. The sanitary, (or even a street sanitary), tee on its back facing upward at a 45 degree angle with a street 45 restoring it to horizontal. Then out of the bottom of the sanitary tee into a "Y" on its back and you will not add any depth and will comply with the strict code interpretation.
