Show Low winters put weight on your water heater
Winter nights here average 21°F from December through February, and your water heater works to make up the difference between that cold ground water and the hot water at your tap. The burner or the heating element runs longer and more often to keep up, and that extra run time wears on the thermostat and the heating element or burner assembly sooner than it would somewhere milder.
Winter storms hit this county often, 137 of them over the last ten years, along with 162 damaging wind events. Power in Arizona goes out for 24 hours or more in about 7% of households in a given year. If yours is electric, an outage means no hot water until power is back. If it runs on gas with a standing pilot, it should relight on its own, but an outage during a cold stretch is still when you notice a weak water heater failing.

- Why is my water heater leaking from the bottom?
- Most often the tank itself has rusted through and is holding water inside the corrosion, which means the tank is failing and needs to be replaced rather than patched. It can also be a loose drain valve, or a fitting that has worked itself loose over the years, and either of those a contractor can tighten or replace without touching the tank. The pressure relief valve can also let water out the side or down the front, which looks like a bottom leak once it runs down and pools underneath. A contractor needs to look at where the water is actually coming from before anyone can say which of these it is.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that sits in the pilot flame and tells the gas valve the flame is lit. Once it wears out it can't confirm the flame anymore, so the gas valve shuts off the pilot as a safety measure. It can also be a draft blowing the flame out, or a dirty pilot orifice restricting the gas. 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. Mineral buildup on the heat exchanger is common and is cleared with a descaling flush, especially on units that have been running for years without one. Ignition failures, sensor faults and error codes usually point to a specific part, like an igniter or a flow sensor, that a contractor can test and replace. A full replacement is only needed when the heat exchanger itself has failed or cracked.
