Hi everybody,
I'm re-locating the toliet in my master bathroom. I cut through my concrete floor and cut my exisiting 3" horizontal cast iron drain line. I left a 12" stub on the cast iron to connect new PVC plumbing.
My problem is that the 12" cast iron stub doesn't slope toward the main stack..apparently it never did. It slopes away from the main drain stack at about 1/2" per foot. I can only assume the rest of my plumbing beyond the hub where the cast iron stub connects to the main drain stack is sloping properly!
How do I properly extend the toliet drain line another 6ft if the cast iron stub slopes the wrong way?
My options are...
1. Connect straight to the end of the cast iron stub and don't worry about the wrong slope
2. Correct the angle of the slope by installing a 22 degree PVC elbow close to the end of the cast iron stub
3. Remove more concrete floor and remove part the cast iron coupling hub at the main drain stack.
Which one?
Thanks,
