If a building inspector is due to arrive and the plumbing system has high pressure, what immediate action is advisable?

1. Prepare for a potential lawsuit

2. Install a pressure reducing valve

3. Increase the number of faucets

4. Use a long hose for temporary pressure relief

The correct answer is: Install a pressure reducing valve

Installing a pressure reducing valve is advisable because it directly addresses the issue of high water pressure within the plumbing system. High pressure can lead to several problems, including leaks, pipe bursts, and damage to fixtures. By using a pressure reducing valve, you can effectively control and lower the water pressure to a safe level before the building inspector arrives. This proactive measure demonstrates compliance with safety standards and helps ensure the plumbing system operates efficiently without causing damage or safety hazards. Addressing high water pressure with a pressure reducing valve also aligns with building codes and regulations, which typically require systems to operate within specified pressure limits for safety and performance. By taking this step, you not only prepare for the inspection but also safeguard the integrity of the plumbing system and avoid potential costly repairs down the line.
