Occupations: plumbers; testing requirements for backflow prevention assemblies; modify.

Michigan House Bill 6253 amends the Skilled Trades Regulation Act to clarify that testing backflow prevention assemblies on automatic fire suppression systems does not require a plumbing license. The bill also makes minor grammatical corrections to existing language regarding who is responsible for proper installation and code compliance. These changes directly affect plumbers, contractors, and other professionals working in Michigan by specifying when a license is not required for specific plumbing tasks.
