I posted this in the wrong spot so here it is again.
I am in the process of pushing out a wall to make a larger more useful laundry and I am thinking of adding a half bath at the same time. The run for the laundry (2")side of things would only increase by 13 or so feet, however I will need to add 3" pipe to accomodate the toilet. This new run would be about 60 feet to tie into the existing line on it's way to the septic system. I understand that I might as well cut out the old 1 1/2 line that looks after the old laundry and tie the new 2" laundry line into the new 3" line, the part I need help with (if I'm not way off base to start with) is the venting of the new plumbing. I started out (when the wife didn't want a half bath) with a simple venting system that would go from the "new" laundry box up into the attic, back the 13 feet and tie into the existing vent line through the roof, now with a toilet involved I'm not sure that would work. I also understand that the toilet must be downstream of the other connections like washing machine.
Sitting on her majesties new proposed throne the new 3" run would be 6' straight out and then somehow connect to the left to the washing machine and vent and to the right would be the 55' ish run in the crawlspace to the main line.
I think my biggest problem is is the 2" vent going to be enough or do i need to add another and where?
