The Institute is proud to announce that all of their members have received third-party verification for manufacturing cast iron soil pipe and fittings from a MINIMUM of 96 percent recycled content.
Cast Iron has, for hundreds of years, been the preferred piping material throughout the world for drain, waste, and vent plumbing applications and water distribution. Gray iron can be cast in the form of pipe at low cost and has excellent strength properties. Unique corrosion resistance characteristics make cast iron soil pipe ideally suited for plumbing applications.
