What San Bernardino winters do to your water heater
Winter nights here average 39°F from December through February, and that cold reaches a tank sitting in a garage or outside. The burner or heating element has to cycle more to keep up, and that added work is what wears out a heating element or an igniter before its time.
Power matters too. The county has logged 89 winter storms and 425 damaging wind events over the past ten years, and statewide, 17% of households lost power for 24 hours or more in 2024. Most water heaters come back on by themselves once power returns, but a storm that knocks it out during a cold night means cold water until it does.

Repair makes sense when an element, thermostat or gas valve has failed.
Replacement makes sense when the tank itself is leaking.
- Why is my water heater leaking from the bottom?
- Most of the time this means the tank itself has rusted through and is failing, not just a loose fitting. Sediment builds up on the bottom of the tank over the years and eats away at the steel underneath it. Once the tank is actually leaking, patching it is not an option. A licensed plumber can confirm whether the leak is coming from the tank or from a drain valve or fitting above it, since those can sometimes be tightened or replaced.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn out thermocouple, the small sensor that tells the gas valve the pilot is burning. When it fails, the valve shuts off the gas as a safety measure even though the flame is fine. A dirty pilot orifice or a draft in the room can also blow the flame out. If a standing pilot won't stay lit at all, it will not come back on its own, and a plumber will need to check the thermocouple, the gas valve, and the vent for the actual cause.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Mineral buildup on the heat exchanger is one of the most common issues, and flushing the unit often restores it. Igniters, flow sensors, and venting can also fail and be replaced without swapping out the whole unit. A licensed plumber can run the error codes most tankless units display to point straight to the failed part.
