Massachusetts Plumbers Journeyman Practice Exam

When must the plumbing of a building have an independent connection to a public sanitary sewer according to regulations?

1. approval of materials by the State Board

2. using the same material as existing stack for alterations within a stack

3. a single separate connection is not feasible in the opinion of the Inspector

4. sole approval of the building owner

The correct answer is: a single separate connection is not feasible in the opinion of the Inspector

In plumbing regulations, having an independent connection to a public sanitary sewer is typically required for safety and efficiency reasons. This ensures that each building has its own dedicated connection to the sewer system, preventing potential issues such as backups or overloading of the system. The option C stating that a separate connection is not feasible in the opinion of the Inspector is correct because it suggests that the decision is based on practicality and necessity rather than personal preferences. The approval of materials by the State Board (option A), using the same material as an existing stack for alterations within a stack (option B), and sole approval of the building owner (option D) are not directly related to the requirement of having an independent connection to a public sanitary sewer.
