Cast iron or copper for DWV in new basement branch

Posted by Elin Pedersen on August 12, 2001 at 22:32:17:
Just got my building permit - great, except it turns out that PVC and ABS are banned in my neck of the woods. So it looks like I am left with a choice between cast iron and copper. How do I choose? The new branch I am putting in will connect to the main stack which is 4" cast iron and there is enough slope to accommodate even a 3" pipe. The new branch line must be at least 3" and approx. 30' long to accommodate 1 toilet, 1 washer, 4 sinks/tubs. I believe that most California codes accept no-hub connections of cast iron below ground, but I need to dbl.check. I hope that you can advise me on this: - what are the issues in choosing between cast iron or copper? - is this a job I have any chance of doing myself (I am pretty smart but an amateur nevertheless)? Thanks -- elin
