    90 in Toilet Drain?
    I’m in the process of remodeling my basement, and would like to redirect a drain for a 1st floor toilet. The drain pipe currently comes through the floor, down to the bottom of the joist, takes a 45 towards the foundation wall and about 3 feet down the wall takes another 45 and then the pipe runs down next to the foundation wall. I would prefer not the have to box in around this with the framing.

    Could I put a 90 in after the pipe comes through the floor, run the drain through the joist, and then another 90 and have the pipe run down next to the foundation?

    Thanks

    Hi Scott,

    I do not advocate the use of 90's in drainage, they slow down the flow allowing solids to drop and build up into a clog. I much prefer using 45's to make a turn.
    Having said that, sometime you can't get away from using a 90, but if you must make it a long sweep 90,(see image) and not a short 1/4 bend.
    Good luck, tom
