Plumbing Code Requirements - R. Konyndyk
Act 230, P.A. 1972, as amended
The act created the Construction Code Commission
and prescribed its functions; to authorize the commission to promulgate
rules for each affected board; provide for statewide approval
of pre-manufactured units; provide for the acceptance of new products
and installation techniques; to provide for administration and
enforcement of the act; and establish remedies and penalties for
violations of the act.
The act allows a governmental subdivision
a. by ordinance, adopt a nationally recognized
model code and provide enforcement, section 8
b. by ordinance, assume responsibility for
administration and enforcement of the state code, section 9
Local ordinance requirements pertaining to
the plumbing code must be approved by the Construction Code Commission.
Prior to submission to the commission the plumbing division chief
evaluates the ordinance for conformance to the criteria established
in section 8 of the act.
Permit requirements are placed in the act
and expanded upon in the various codes where requirements are
Act 222, P.A. 1901
This first plumbing law is still in effect
except where superseded by act 266. Section 7 of Act 222, P.A.
"But all inspectors of plumbing so detailed
designated and appointed, and all inspectors shall not be engaged
directly or indirectly in the business of plumbing, during the
period of their appointment, . . .
Act 266, P.A. 1929, as amended
Act 266 is the present plumbing licensing
law for the installation of plumbing. Plumbing inspectors are
required to be licensed the same as installers in section 4.
Backflow preventers are incorporated in
the scope of plumbing as defined in section 1 of the act. The
installation and repair of these devices shall only be accomplished
by licensed individuals through the permit process. Permits may
only be obtained by an authorized master plumber.
The plumbing law also establishes and defines
the authority of the State Plumbing Board. The board in their
concern for proper testing of the devices has implemented a Backflow
Preventer Testing Seminar through board action. Presently,
this is being conducted through the Michigan Plumbing & Mechanical
The seminar is open to licensed master and
journey plumbers, plus others who need to test back preventers
at their place of employment. Upon satisfactory completion,
licensed plumbers receive a state approved certificate for general
testing. Other graduates receive a letter of completion, limiting
testing to the premises of their current place of employment.
The State Plumbing Code
The state plumbing code consists of the BOCA National Plumbing
Code/1990 edition and the Department of Labor Construction Code
Commission General Rules, the Part 7.
The State Plumbing Code Rules are promulgated
in accordance with Act 306, P.A. 1969, as amended, the Administrative
Procedures Act. The administrative rules process, while taking
a great deal of time, insures the system of checks and
balances in rule development.
The rules are technical amendments to the
national code. Technical amendments are commonly necessary to
address local or state statutes and concerns which were not considered
in the national code development. For example, heat exchangers
in the state code are different than national requirements to
address Michigan Department of Health concerns. These concerns
were identified with our common backflow preventers tester training
The State Plumbing Code permit requirements
are located in article I of the national code and installation
requirements are located in article 15.
The following section outline with notes
has the technical amendments in bold print. Specific information
on each section will be provided during the class instruction.
