CISPI is dedicated to aiding the plumbing industry and addressing important technical aspects relating to
the manufacture and installation of cast iron soil pipe and fittings and their use in the marketplace.
Through the preparation and distribution of technical data, work with local and national code bodies, and
by calling on code officials and plumbing engineers, CISPI helps create a better understanding of the
merits of specifying and installing cast iron soil pipe and fittings. CISPI maintains a comprehensive
quality control program for its member foundries. Each plant location is audited during the course of the
year to help ensure that cast iron soil pipe and fittings bearing the Institutes collective trademark (CI® )
meet the appropriate CISPI and ASTM standards. (www.cispi.org).
