There are several signs your water heater might be on its last legs. Look out for:
- No hot water or not enough hot water
- Leaking around the tank
- Rusty or discolored water
- Strange noises coming from the unit
- Water heater age (over 10 years for gas, over 12 years for electric)
If you notice any of these, call your licensed plumber for a diagnosis. They can advise on repair or replacement.
