Water Heater Leaking? Identify the Situation Before Choosing a Fix

Updated November 10, 2026

Illustrative DWH technician and homeowner inspecting the base of a water heater

Water beside a heater does not by itself prove the tank has failed. The source might be a connection, a valve, condensate from certain equipment, or a nearby plumbing issue. Active water needs attention, but the repair decision should follow identification of the source.

Stay clear of immediate hazards

Do not enter standing water to reach electrical controls or the heater. If you smell gas, leave and call 911 and your gas utility from a safe location. Flood-exposed equipment needs qualified evaluation before operation. Tell the service team if the area is unsafe to enter.

Record where and when water appears

From a dry, safe position, describe whether moisture appears near the top connections, around the base, in the pan, or at a discharge pipe. Note whether it is constant or appears only during heating. A safe photograph can help with triage, but tracing the leak should not require dismantling the equipment.

Do not cap or block a relief-valve discharge pipe. That device is part of the safety system; recurring discharge needs diagnosis rather than concealment.

Match the solution to the actual source

A serviceable connection or component may be repairable. A confirmed leak through the storage tank itself generally leads to replacement of the heater. Ask the technician to show or explain the source, the recommended work, and any uncertainty before you approve it.

Coordinate water damage separately

Replacing or repairing the heater addresses the equipment problem. Drying and repairing damaged flooring, walls, or other building materials may require a restoration company. DWH can coordinate the water heater portion with your property manager, restoration contractor, or insurance contact when authorized; insurance coverage is determined separately.

Choose your next step

Request service for diagnosis, or review installed replacement pricing. Share the address, access details, visible conditions, and who approves the work. Our team confirms scheduling and the appropriate service scope.
