What should I do when my Hot Water Heater is Leaking?

When you discover your hot water heater is leaking, you must act quickly to prevent water damage and safety hazards. Follow these expert steps to manage the situation safely:

1. Shut Off Power and Water

Immediately turn off the power source. For electric heaters, flip the labeled breaker in your electrical panel to OFF. For gas heaters, turn the gas supply valve perpendicular to the pipe. Next, shut off the cold water inlet valve located at the top of the tank to stop more water from entering.

1. Contain and Locate the Leak

Place buckets under the leak and use a mop to manage water on the floor. Dry the area and monitor for 30 to 60 minutes to identify the source. Common points include the pressure relief valve, drain valve, fittings, or tank seams.

1. Perform Initial DIY Steps

If a fitting is loose, you can try gently tightening it with an adjustable wrench. If sediment buildup is suspected, you may need to flush the tank using a garden hose attached to the drain valve.

1. Know When to Call a Professional

Avoid attempting DIY repairs on high-pressure components like the pressure relief valve. If the tank is leaking from the bottom, shows significant corrosion, or if the unit is over 10 to 15 years old, professional repair or replacement is required. Professional intervention ensures the unit is handled safely and effectively.
