I'm adding a master bathroom onto my house and converting an old 3-piece bathroom to a powder room. One of the challenges has been figuring out how to add the the drain line from the addition into the original 4" soil stack, another has been how to re-work the powder room toilet and laundry discharge line back into the soil stack, and finally the close proximity of it all (which actually might be a blessing given the close quarters of the crawlspace).
The first photo shows a plumber's attempt at it; I cringed right off the bat at the sanitary tee turned on its side at the Fernco fitting. Then the use of 90* and 45* street fittings in an "S" (why not just use the 45* turned over?) to accept the upstairs portion of the soil stack at a 45* angle. And then the toilet/laundry drain just seems like a mess to me. And no cleanout. And no PVC primer.
Anyway, I took the day off from work yesterday and re-did it all as shown in the second photo below. I used a wye and a combo wye turned horizontally and back-to back-to accept the drain line from the bath addition and upstairs portion of the soil stack. I then used separate sanitary tees to tie in the 3" toilet line and 2" laundry drain line. Then I was able to put the upstairs soil stack run back to horizontal and tied back in with a 90* elbow and add a cleanout. I'm pretty happy with it....I think if I could change anything it would have been to use a 3" long sweep 90* on the toilet bend, but hopefully the short bend will be fine.
Any comments or feedback would be appreciated.
