The water works representatives tell me that cast iron pipe is no longer manufactured for water service, and I need to specify ductile iron pipe.
Cast iron is a commonly used term to describe many types of iron.
The casting method involves pouring the iron in a molten or liquid form into a mold which defines the shape of the finished product. Irons are also sometimes identified by color or physical properties. Cast iron soil pipe and fittings are produced from this type of iron. Cast iron tubs, drains, many iron body valves, fire hydrants, automotive engine blocks, brake drums, manhole covers and wrecking balls are also made of this type of iron. One of our members produces ductile iron water pipe.
