Water Heater Repair

Common symptoms and what they usually mean

• No hot water at all — failed element, thermostat, pilot, or igniter
• Hot water runs out fast — sediment buildup, failed dip tube, undersized unit
• Rumbling or popping — sediment on the tank bottom
• Rusty hot water — corroding tank or spent anode rod
• Water pooling under the unit — connection, valve, or tank failure

What to do if it is leaking

1. Shut off the cold water supply valve at the top of the heater.
2. Turn off power at the breaker (electric) or set the gas valve to off.
3. Keep clear if you see steam or hear the relief valve discharging.
4. Request professional help before draining the tank yourself.

Repair or replace?

Age and failure type usually decide. A component failure on a relatively new unit is a straightforward repair. A tank that has rusted through, or repeated failures on an older unit, generally point toward replacement.
