Common water heater problems
- No hot water: on gas units, often the pilot, thermocouple or gas control; on electric units, a heating element or thermostat.
- Leaks: a leaking valve or fitting can often be repaired; a leaking tank usually means replacement.
- Rumbling or popping: often sediment build-up.
- Rusty water or not enough hot water: may point to an aging tank.
Safety first: if you smell gas, leave the house and call your gas utility from outside.
