Hey guys I have a very good friend that is a building admin at an architectural firm and they are working on a project where the city wants them to use cast iron for the lateral lines but they want to use schedule 40 pvc. I can't give out a lot of info but I can tell you the job is in southern California on a new construction project 1 mile from the San Andreas fault line. I think plastic would be the way to go. Do you guys have different opinion or the same? By all means I am not the expert so if you guys think differently, I am all ears. However if I am right on this is there any documentation proving this would be the best method for the area?
