What should be installed if the supply pressure exceeds the working pressure of the water heater tank?

• A. Pressure Reducing Valve
• B. Expansion Tank
• C. Flow Control Valve
• D. Relief Valve

Answer: (A)

If the supply pressure exceeds the working pressure of the water heater tank, it is essential to install a pressure reducing valve. The primary function of this device is to lower and regulate the incoming water pressure to a safe and acceptable level that the water heater can handle. Water heaters are designed to operate within a specified pressure range, and exceeding this can lead to damage, inefficiencies, and safety hazards. By using a pressure reducing valve, the water pressure entering the heater is automatically adjusted to ensure it does not exceed the manufacturer’s recommended maximum working pressure. This helps protect the integrity of the tank, prevents potential leaks or ruptures, and extends the lifespan of the water heater system. Thus, installing a pressure reducing valve is a crucial step in maintaining system safety and performance.
