Water heater is leaking water from the bottom of the unit

Safety first: Turn OFF power and close the cold water supply valve to the heater. If leak is severe, also turn OFF gas. Water damage and electrical hazards are possible.

Steps to check:

• Identify leak source: Remove the front cover and use a flashlight to locate where water originates (heat exchanger, fittings, relief valve, condensate line).
• Tighten fittings: Gently tighten accessible water connections if they appear to be seeping.
• Check pressure relief valve: If water is dripping from the relief valve discharge, system pressure or temperature may be too high or the valve may be faulty.
• Differentiate condensate: On condensing models, small amounts of clear water from the condensate drain are normal; large or continuous leaks are not.

When to call a professional: A leaking heat exchanger or relief valve requires professional replacement. Do not operate the unit with an active leak.
