Michigan Construction Code Commission Rejects Cast Iron Materials from MWI Import Products for State Construction Projects

The Michigan Construction Code Commission today unanimously approved the August 22, 2007 recommendation of the Michigan Plumbing Board to deny approval of imported cast iron soil pipe and fittings from MWI Import Products for use on state construction projects in the State of Michigan. MWI's request for official approval was denied after MWI was unable to provide proof that their products conformed to applicable standards referenced in the Michigan Plumbing Code and failed to comply with an earlier resolution of the Plumbing Board, according to a written report submitted by Michigan Chief Plumbing Inspector Bob Konyndyk.

An official record of the proceeding will be available on the Michigan Construction Code Commission web site at

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 receives a comprehensive audit three times every year to help ensure that cast iron soil pipe and fittings bearing the Institute's collective trademark (CI) meet the appropriate CISPI and ASTM standards. NSF International has accredited CISPI's quality control program to validate the compliance of member products with those standards.
