Replacing cracked cast iron sewer line

Posted by Tony on December 31st, 2002 02:52 PM

I have a 4" cast iron line that runs horizontal to the wall then 90's and goes out through the concrete wall. The 90 degree has a cleanout with a crack. The crack runs on top of the cleanout and doesn't leak due to it's position.
The house is early 40's construction and I want to replace the line. However, my problem is whether or not the no-hub coupler will be able to support the weight of about 30' of cast iron due to a vent that goes to the top of the roof, and all the other pipe and fittings. What if I replace it with ABS pipe? How does it vent to (attach to) the roof? Did they use hangers back in the 40's?

If I had more room I could support it and not worry about it, but I only have, maybe, a foot of room that the original cast iron 90 takes.
