Massachusetts Plumbers Journeyman Practice Exam

What is required for the use of materials not covered by plumbing standards according to the regulations?

1. approval of materials by the State Board

2. approval by the local Inspector

3. sole discretion of the plumber

4. review and approval by the local city council

The correct answer is: approval of materials by the State Board

The requirement for the use of materials not covered by plumbing standards is that they must receive approval from the State Board. This ensures that any materials utilized in plumbing installations meet safety and performance standards established at a higher regulatory level. The State Board evaluates these materials to determine their suitability and reliability, which helps maintain the integrity of plumbing systems and protect public health. Other options, such as local inspector approval or reviews by local city councils, may not have the same authority or comprehensive standards as the State Board. A plumber's discretion could lead to inconsistent quality and safety, which is why stringent oversight from the State Board is necessary for materials that fall outside standard regulations.
