Massachusetts Plumbers Journeyman Practice Exam

What is the requirement for materials used in water service piping outside a building?

1. A. No specific requirement

2. B. To match the building's color scheme

3. C. Specified by the local municipality

4. D. Imported from overseas

The correct answer is: C. Specified by the local municipality

The requirement for materials used in water service piping outside a building is typically specified by the local municipality. Local building codes and regulations dictate the appropriate materials to ensure safety, suitability, and compliance with environmental and health standards. This ensures that the materials used are suitable for the region's climate, soil conditions, and other environmental factors. Other options do not align with standard practices. There is usually a specific requirement for materials; hence stating "no specific requirement" is incorrect. Matching a building's color scheme does not pertain to functionality or safety standards and would not be a legitimate requirement for plumbing installations. Additionally, while some imported materials may be allowed, there is no stipulation that they must be sourced from overseas, as local materials are often preferred for ease of access and compliance with local codes.
