Water Heater Heating Element Corrosion in Mesa, AZ
Why Water Heater Heating Elements Fail Faster in Mesa
If you've noticed your electric water heater struggling to produce hot water, or your energy bills creeping up without explanation, a corroded heating element is one of the most common causes — especially here in the East Valley.
Mesa's water supply runs 15+ grains per gallon of hardness, well above the national average. That mineral content doesn't just show up as scale on your fixtures and shower doors — it builds up directly on the heating elements inside your water heater tank. Over time, that buildup insulates the element, forces it to work harder, and eventually causes it to corrode and fail.
Homes with softer water can get 10-15 years out of a heating element. In Mesa, without a water softener, that lifespan often shrinks significantly.
Signs Your Heating Element Is Failing
Most heating element problems show up gradually before they fail completely. Watch for:
Lukewarm water that never gets fully hot — often the first sign, especially if you have a dual-element tank and only one has failed
Water heater running constantly — the element works overtime trying to reach temperature
Rising electric bills — a struggling element draws more power for less output
Discolored water or a rotten-egg smell — can indicate corrosion inside the tank itself, not just the element
A tripped breaker on the water heater circuit — often a sign the element has shorted out
If you're noticing more than one of these, it's worth having a technician take a look before you're left with no hot water at all.
Repair or Replace? How Technicians Make the Call
When a heating element fails, our technicians test both elements (most residential electric water heaters have two — upper and lower) along with the thermostat and wiring to confirm the actual point of failure. In many cases, if one element has corroded, the second isn't far behind, so we'll walk you through whether replacing both now makes more sense than a return trip in a few months.
We'll also check the surrounding components, since a corroded element in hard water conditions is sometimes a sign of broader tank wear. If the tank itself shows advanced corrosion or sediment buildup, we'll be upfront with you about whether repair or full water heater replacement is the better long-term investment.
Preventing Premature Element Failure
A few things can extend the life of your heating elements:
Install a water softener — the single biggest factor in reducing mineral buildup on elements and inside the tank
Flush your water heater annually — clears sediment before it hardens into scale
Set your thermostat to 120°F — lower temperatures reduce mineral precipitation compared to higher settings
Schedule regular maintenance checks — catching a struggling element early is far cheaper than an emergency replacement
