Which button should be pressed to stop filling with cold water in the Water System?

• A. Cold Water Fill Button
• B. Automatic Water Drain Button
• C. Main Valve
• D. Emergency Stop

Answer: (A)

The essential idea is that controlling the cold-water inflow is done directly with the Cold Water Fill Button. This button is the interface for starting or stopping the cold-fill circuit, so pressing it while cold water is filling changes the state to stopped, halting that specific supply without affecting hot water or other functions. The other options serve different roles: the Automatic Water Drain Button removes water from the system but doesn’t specifically stop cold-fill; the Main Valve would shut off the broader supply and could affect more than just cold water; the Emergency Stop halts all operation for safety, not just the cold-fill flow. So, pressing the Cold Water Fill Button is the correct way to stop filling with cold water.
