What is the plumbing code?

The plumbing code controls the design and installation of plumbing systems, including sanitary and storm drainage, sanitary facilities, water supplies, and storm water and sewage disposal in buildings. The 2009 Michigan Plumbing Code went into effect August 20, 2010. Provisions for one- and two-family dwellings are included in the 2009 Michigan Residential Code.

Plumbing is the practice, materials and fixtures used in the installation, maintenance, extension, and alteration of all piping, fixtures, plumbing appliances, and plumbing appurtenances in connection with sanitary drainage or storm drainage facilities; venting systems and public or private water supply systems, within or adjacent to any building or structure.
