Regular maintenance extends tank life by years, keeps recovery and capacity where they should be, prevents the sudden failures that flood floors, protects manufacturer warranty coverage, and catches safety problems on gas units. In Albuquerque’s hard water, it is the difference between eight years and twelve.

Longer Tank Life

This is the main event. Mineral sediment settles on the tank bottom and insulates the burner from the water above it — so the burner runs longer and hotter, stressing the glass lining until it cracks and the steel beneath begins corroding. Annual flushing removes that sediment before it does the damage. Replacing the sacrificial anode rod when it is consumed protects the tank the same way.

Restored Capacity and Efficiency

Sediment takes up volume and insulates the heat source, so an unflushed five-year-old tank delivers less hot water, more slowly, using more energy than it did new. Flushing recovers most of that.

Fewer Emergencies

A tank that fails while nobody is home dumps 40 to 50 gallons onto whatever is below it. Maintenance visits catch corrosion, weeping connections, and a failing T&P valve while they are still small, which turns an emergency into a planned replacement on your timeline.

Safety

On gas units, service includes combustion, venting, and burner checks. A blocked or disconnected flue is a carbon monoxide risk, and it is not something you notice on your own. The temperature and pressure relief valve gets tested too — it is the last defense against an over-pressurized tank, and it can seize shut with no outward sign.

Warranty Protection

Many manufacturer warranties require documented professional maintenance. Skipping it can void coverage on exactly the expensive failure you most want covered.

How Often

Once a year for tanks. Once a year for tankless, where the visit is a heat exchanger descaling — critical in this water.

Treat the underlying cause with a water softener, which protects fixtures and appliances too. Care Club members get scheduled service. Contact B. Carlson for water heater maintenance.
