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

If your hot water heater is leaking, you must act quickly to prevent water damage and safety hazards. Follow these essential steps provided by NorthStar Heating and Cooling:

1. Shut Off Utilities

Immediately turn off the power supply at the circuit breaker for electric units or shut off the gas supply for gas units. Next, turn off the cold water inlet valve located at the top of the tank to stop more water from entering.

1. Locate the Source

Dry the area with towels and monitor the tank for 30 to 60 minutes. Check common areas such as the pressure relief valve, drain valve, inlet/outlet fittings, and the tank base. A leak from the bottom often indicates corrosion or a failed seal.

1. Contain and Mitigate

Place buckets under any active drips and mop up standing water. For minor issues, you can try gently tightening loose fittings with a wrench. If sediment is the cause, you can attempt to flush the tank by attaching a garden hose to the drain valve.

1. Seek Professional Help

Avoid DIY repairs on pressure components. If the tank is corroded, over 10 to 15 years old, or the leak persists, contact a professional for repair or replacement. In Calgary, NorthStar Heating and Cooling provides emergency services for these situations.
