Water Heater Maintenance: Maximizing Longevity and Efficiency

A water heater is one of those appliances nobody thinks about until it stops working. A little regular maintenance goes a long way toward avoiding that moment, and toward getting the most out of the unit you already have.

The One Habit That Matters Most: Annual Flushing

Flushing your water heater once a year is the single most useful thing you can do for it. Sediment and mineral buildup settle at the bottom of a tank over time, especially with the Valley's hard water, and that buildup makes the unit work harder to heat the same amount of water. A regular flush clears that out and keeps the unit running the way it's supposed to.

What a Flush Actually Involves

A flush clears sediment out of the bottom of the tank by draining a portion of the water through the drain valve, typically found near the base of the unit. It's a straightforward process in concept, but it involves shutting off power or gas to the unit first and handling water that's still hot, which is why it's a job worth handing to a licensed plumber.

How Long Should a Water Heater Last?

In Arizona, the average water heater lasts somewhere between 7 and 12 years. Where a specific unit falls in that range has a lot to do with water quality, usage, and how consistently it's been maintained, which is exactly why the annual flush matters as much as it does.

Storage Tank vs. Tankless Maintenance

Storage tank water heaters and tankless units both benefit from an annual flush, but they show wear differently. A tank style unit tends to lose hot water capacity gradually as sediment builds up at the bottom, while a tankless unit is more likely to show flow or temperature inconsistency as scale builds inside the heat exchanger. Either way, the fix is the same: keep the mineral buildup from Arizona's hard water from getting ahead of the unit.

Signs Yours Needs Attention

• Getting less hot water than you used to
• Water that's hotter than expected, or inconsistent
• Discoloration or an odd smell in the hot water
• Unusual noise coming from the tank
• No hot water at all
• Moisture or dampness near the unit
• A leak anywhere around the tank
• The smell of gas near the water heater

The gas smell is the one that shouldn't wait. Everything else is worth a call soon, but for that one, get everyone away from the unit and call right away.

Hard Water Is Working Against the Unit Too

A water softener does more than protect your fixtures, it protects your water heater as well. Less mineral buildup inside the tank means less strain on the unit and fewer of the symptoms above showing up early. It's one of the reasons softening and water heater care tend to go hand in hand out here.

Setting the Right Temperature

The temperature a water heater is set to affects both efficiency and safety. A unit set too high burns more energy than it needs to and increases scalding risk, while one set too low can struggle to keep up with demand. If you've never checked what yours is set to, it's worth asking a licensed plumber to take a look.

Brands We Work With

Majesty Plumbing works on water heaters from Navien, Rheem, A.O. Smith, and Bradford White, whether that's an upgrade, a repair, maintenance, or a full replacement.

Repair, Replace, or Just Maintain?

Not every issue means a new unit. Plenty of water heater problems are a straightforward repair, especially when they're caught early. Where a unit is getting close to or past that 7 to 12 year mark and starting to show more than one of the signs above, replacement usually makes more sense than repeatedly repairing an aging tank. That's a conversation worth having with a plumber rather than guessing.

If a replacement turns out to be the right call, financing is available, and seniors, military members, and first responders qualify for 10% off, up to $500, on service.
