Water heaters usually give warnings before they fail completely. Learning to spot them can help you schedule a repair on your terms instead of facing a cold shower or a flooded utility room.
Common Warning Signs
- Not enough hot water, or water that turns lukewarm quickly.
- Rumbling, popping, or banging from the tank, often caused by sediment buildup.
- Rusty or discolored hot water.
- Moisture or puddles around the base of the tank.
- A unit that is more than 10 to 12 years old.
- Rising energy bills with no change in usage.
Leaks Need Quick Attention
A small drip from a fitting or relief valve may be repairable. Water leaking from the tank itself usually means internal corrosion, and the tank will need replacement.
If the Tank Is Leaking
Turn off the cold water supply to the heater and shut off power (electric) or set the gas control to off (gas) if you can do so safely. Then call for help.
Repair or Replace?
Failed heating elements, thermostats, and anode rods on newer units are often worth repairing. An older tank with repeated problems, or any leaking tank, is usually better replaced. A qualified provider can help you decide.
