Hello,
Thanks to all who contribute to this forum.
I'm adding a second sink to create a double-sink bathroom and am not sure how to run the drain. At the spot where I'm adding the sink, there is a cast iron pipe running from the roof to the crawl space where it joins with the drains of a toilet, sink and tub, that are on the other side of the wall I'm working on.
Because of the wall studs it does not look like I can hook into the drain of the first sink (which is cast iron as well).
1. Do I hook the drain of this new 2nd sink into this cast iron vent / drain? If so, how? Two couplers and a PVC T?
2. An easier approach seems to be to run PVC down into the crawl space where I can hook into the cast iron pipe there. This is easier because a plumber had already replaced the tub drain with PVC with a rubber coupler to the cast iron pipe. So I can hook into the PVC part. The distance is about 3' down and 3' horizontally (sloped, of course).
I tried to read some code regulations but I'm not sure I understand them correctly.
Thank you in advance for all advice.
Ron
