Hello all.
Just joined this forum looking for some advice.
I have a master bath that was rough plumbed 10 years ago. We are only starting to convert it to a finished master bath (until now, it's just been used as storage). The problem is, the location of the 3" waste pipe is about 5'6" from where it needs to be. Unfortunately, my floor joists run perpendicular to the direction it needs to move so I would have to cut holes through four 10" floor joists to route the pipe to the new location.
First question is, can I get enough slope for a 3" pipe moving it 5'6" to drain correctly? (it currently comes up through a wall and then moves about 1'6" horizontally to the point where the flange comes through the floor)
Second question is, given that the joists are only 10", can I even punch a 3" hole through 4 of them without weakening them too severely? If it can be done, how do you shore up the joists..... laminate them with glued plywood?
Thanks for any info.
