Cold groundwater and long winters wear on your water heater here
Pullman winters run long. Homes need heat from September through May, and incoming water runs cold for most of that stretch. Your water heater has to work harder to bring it up to temperature, and the burner or heating element cycles more to keep up. That extra work adds up on the thermostat, the heating element, and the burner assembly.
Winter storms in this county are not rare. Whitman County has seen 58 winter storms and 27 damaging wind events over the past ten years, and power outages follow. Most gas water heaters relight on their own once power is back, but electric units and any with electronic ignition may need a reset. If your water heater was struggling before an outage, the restart can be when it finally quits.

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 often the tank itself has corroded through and is failing from the inside. Water heaters have a glass lining inside the steel tank, and once that lining cracks, the tank rusts and starts to weep at the seams or the bottom. It can also be a loose drain valve or a fitting that's failed, which a contractor can check before assuming the tank is done. A tank leaking from the bottom from corrosion can't be patched or repaired, it needs to be replaced.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that tells the gas valve the pilot is actually burning. When it wears out, it can't sense the flame properly and shuts the gas off even though the pilot lit fine. It can also be a dirty pilot orifice or a draft blowing the flame out. A contractor can test the thermocouple in a few minutes and replace it if that's the cause.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Issues like a failed igniter, a clogged inlet filter, mineral buildup on the heat exchanger, or an error code from a sensor can usually be fixed without replacing the unit. Tankless units also last longer than tank models, so repair is often the better option even years in. A contractor can pull the error code and tell you what's actually failing.
