Hello Everyone!
There is a drain pipe (is Soil Pipe the correct term?) which runs well below the floor joists in my basement. I've been bashing into it for years. I have the opportunity to move it up, into the joist bay. (I'm replacing the floor in the bathroom upstairs.)
The pipe is from a toilet and it ends in a 3x3x3x1 1/2" fitting on a stack. As it exists, the closet flange has a pipe going through the floor & into a 90 degree elbow. Then, a pipe runs about 60" to the 3x3x3x1 1/2". All fittings above ground are Schedule 40 PVC.
My "Great Idea" is to use a toilet flange that fits into a 3" Schedule 40 pipe and use a street 90 directly into the flange. I'd travel along in the bay for about 38" and connect it to two 45 degree bends that are connected by a short length and rolled into position. The lower 45 will be attached to a short stub of pipe left at the "tree" when I cut out the old. I messed around with some scraps & fittings. Physically, it works and I can pitch the horizontal 1/4" p/ft.
I can't describe it very well, so I put a drawing of "Existing" & "Proposed".
The question is: If I'm using two 45 degree angles will the water run away, leaving the debris behind? What do all of you think?
Thanks for your help!
Paul
PS: Is 1/4" per foot the correct pitch for the horizontal run?
