NM MM-1 Plumbing The NM MM-1 Plumbing exam now reflects updated building codes introduced in 2023, including revised water efficiency standards and modernized venting regulations. Preparation must address these shifts directly—outdated study materials won’t cover changes to fixture ratings or pressure-balance requirements. Staying competitive means engaging with materials that address the current code landscape, not older frameworks.
