Which type of valve should be installed to prevent explosions in hot water systems?

• A. Temperature relief valve
• B. Pressure relief valve
• C. Combined temperature and pressure relief valve
• D. Flow control valve

Answer: (C)

The combined temperature and pressure relief valve is essential for preventing explosions in hot water systems because it simultaneously monitors and regulates both the temperature and pressure of the water within the system. When water is heated, it expands and the pressure within the system increases. If the pressure becomes too high, there is a risk of equipment failure and potentially dangerous explosions. This type of valve is designed to open at specific temperature and pressure settings, allowing excess steam or hot water to escape safely, thus alleviating potential hazards associated with overpressure and overheating. It provides a dual function, ensuring that the water doesn't exceed the optimal operating conditions which could lead to catastrophic failures in hot water systems. By utilizing this combined valve, plumbing systems can maintain safety standards more effectively.
