Which component is used to return excess condensate to the Reserve Feedwater Tank when high level is indicated?

• A. The Dump Valve
• B. Main Feed Pump
• C. Check Valve
• D. Vent Valve

Answer: (A)

When condensate level rises, you need a controlled path to return the extra water to the Reserve Feedwater Tank to keep the loop balanced. The dump valve provides that path; it opens to send the excess condensate back into the RFWT, bypassing the normal feedwater flow and preventing overfill. The main feed pump moves water from the RFWT toward the boiler and isn’t used to return condensate. A check valve keeps flow in one direction but doesn’t actively route condensate back to RFWT, and a vent valve releases gases or steam rather than returning liquid.
