In contract on new deal. They went above and beyond on the build-out it seems. Water lines are ductile iron which connect to copper service lines. Sewer is PVC. Park built in 1978. Based on some google searches, it appears ductile iron is far better than cast iron, but I haven't seen too much wrt MHPs. Also don't see it mentioned in the F&D materials. Anyone have any experience with ductile iron?
