Why Is My Water Heater Leaking?

Water near a heater may come from a loose connection, valve, drain, condensation, nearby plumbing, or the tank itself. Because hot water, pressure, electricity, and fuel may be involved, contain damage only when safe and have the source correctly identified.

Check Water Heater for Leaks

Water damage can cause major issues. Check water heater for leaks.

Difficulty: EasyTypical cost: $0–$20Suggested frequency: Every 6 monthsPriority: Medium

Where do water heaters commonly leak?

Inspect visually around supply connections, the temperature-and-pressure relief discharge, drain valve, fittings, and tank base without touching hot or energized components.

Is condensation normal?

Some high-efficiency equipment produces managed condensate, while humid air can condense on cold piping. Unexplained or persistent water still needs identification.

When is a leak an emergency?

Act promptly for active flow, water near electrical equipment, a relief valve discharging hot water, gas odor, structural damage, or any unsafe condition.

Where is the shutoff valve?

A cold-water supply valve is commonly located above the heater, but configurations vary. Identify controls before an emergency and do not operate damaged valves.
