What Walla Walla winters do to a water heater
Your water heater works harder here than the label suggests. Groundwater coming into the tank is already cold on winter nights that average 29°F from December through February, so the burner or heating element runs longer to make up the difference, and it does this from October through May, eight months of the year.
That long stretch of hard running wears on the heating element and the thermostat that controls it, and on gas units, the burner assembly. The county has also logged 67 winter storms and 37 damaging wind events over the past ten years, and power drops with them. Most tanks come back on by themselves once power returns, but a storm that knocks out power for a day or more while the burner or element is already worn can be what finally pushes a struggling water heater into failure. You notice it as water that will not get hot, or runs out fast, right when you need it most.

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?
- The most common cause is the tank itself failing from the inside, where sediment builds up and corrodes the steel until it gives way. Once that happens the tank cannot be patched or sealed. A leak can also come from the drain valve or a fitting on top that is dripping down the side, so it looks like a bottom leak when it isn't. A contractor can tell you which one you have and whether the tank needs to be replaced.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and no longer signals the gas valve to stay open once you let go. It can also mean the pilot tube is dirty or there's a draft near the pilot that keeps blowing it out. A standing pilot does not run on electricity, so power going out is not the cause. If relighting it doesn't hold, the thermocouple likely needs to be replaced.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. Mineral buildup on the heat exchanger is common and is cleared by flushing the system, especially in homes with harder water. Igniters, flow sensors, and venting issues can also be fixed without replacing the unit. A contractor can run the error code the unit is showing to find out exactly what's failing.
