Toilet drain line through floor joists?
I am in the planning for a remodel (and will be talking with a plumber soon). But, I was hoping I could get one question answered (this should be easy):
What size 2by joist is needed if you need to run a toilet-size drain pipe through it in order to get it to a drop wall (from second story to crawl)?
The toilet would be the only fixture on the run through the joists in this fashion (other fixtures would join in a joist-space near the drop).
I know needing to do this will add cost--having to cut holes for the drain line adds labor. But, I am just wondering how big the joist needs to be. (I have at least 2x10s, not sure if they are 2x12s yet (haven't crawled up there and moved insulation out of the way).
