SPS Intent requires plumbing in buildings intended for human occupancy to be installed and maintained to protect which of the following?

• A. The health and safety of the public only.
• B. Only the structural integrity of the building.
• C. The health, safety and welfare of the public or occupants, and the waters of the state.
• D. The appearance and aesthetics of the plumbing system.

Answer: (C)

The main idea is that plumbing codes exist to protect people and the environment, not just the look or the structure of a building. Placing and maintaining a plumbing system properly ensures safe drinking water, prevents contamination, and avoids health hazards inside the building. It also covers environmental protection by safeguarding the waters of the state from pollution and backflow-related issues that could contaminate rivers, lakes, or groundwater. That broader scope—protecting the health, safety, and welfare of the public or occupants, and the waters of the state—is why this wording is the best one. The other choices miss either the occupant welfare, the environmental protection, or focus on aspects (like aesthetics or structural integrity) that aren’t the primary aims of the SPS intent.
