Thread: Using a 3"san. Tee

  1. #1

    Default Using a 3"san. Tee

    I Have one tight tie in on the job. They are finishing the basment and have to keep a new 3" soil line up in the joist bay. I normally use a combo wye and eigth bend to tie in, but this will bring me down too low. How much would the inspector frown if I drop one branch into a 3" san. Tee. The tee is straight up of course.

    I am using the san tee upright with flow comming into the top ( not horizonal, I wouldnt do that). I normally use a wye with a street 45 to bring the angle up to a 90. This may be fine to use. I was told always to use wyes not san tees. The san tee is a much lower profile than the wye with a street 45. This is a tight spot in joist bay to sub floor. Man I have to get some software with fittings and stuff. Anyone know where I can get that so I can Illustrate some things.

    Just take a picture of some fittings pushed together and post that.
    Much quicker than drawing them.

    Default tee

    IF the tee is vertical with the branch going horizontally off to the side, then the sanitary tee is the NORMAL fitting to use. A "Y" or combo has absolutely no benefits and is sometimes illegal for that situation.
