I am in the process of remodeling an upstairs bathroom. I want to relocate my toilet and this will require running a 3" pipe through my 2" x 10" floor joist. Here is a picture of the floor and where I would like to place the toilet http://home.earthlink.net/~ptl_5/ and the 2 different options for routes I have for running the drain pipe for the toilet. Route "A" would require drilling through 3 floor joist and the middle of the hole would be about 6" from the end of the joist. The other route "B" would require putting a hole where there are 3 joist together. Any help or comments would be great. Thanks.
