Seattle's water heaters run nearly year round
Homes here need heat from September through June, so the water heater is rarely idle. That is ten months of the tank cycling on and off to keep up with hot water demand, and each cycle adds wear to the heating element or burner assembly.
Winter nights averaging 32°F mean the incoming water is colder for longer, so the unit works harder to bring it up to temperature. If power drops, and roughly a quarter of Washington households lost power for at least 24 hours in 2024, an electric water heater will not fire back up on its own. Most gas units with a standing pilot keep running through an outage, but if yours has an electronic ignition, no hot water after an outage is often just that switch waiting to be reset.

A new water heater would cut about $280 a year off hot water for a typical Washington home.

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 reason is a failing tank, corroded through from years of holding water. Once the tank itself has a hole, there's no patching it, the whole unit needs to be replaced. Before you assume the worst, though, check the drain valve and the fittings above the tank. A loose drain valve or a fitting weeping from a bad connection can look like a tank leak but is a simple fix. A contractor can tell you which one you're dealing with in a few minutes.
- Why won't the pilot light on my water heater stay lit?
- Most of the time this comes down to a worn thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out, it fails to hold the valve open and the flame goes out even though the pilot lit fine. A weak pilot flame, a draft near the burner, or a clogged pilot orifice can cause the same thing. It's a part a contractor can test directly rather than guess at.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. Mineral buildup on the heat exchanger, a bad igniter, a failed sensor, or an error code from the control board are all things a contractor can diagnose and fix without replacing the unit. Whether repair makes sense depends on the age of the unit and what's actually failed, which a contractor can tell you after looking at it.
