Routine maintenance is key to catching potential issues before they escalate. A professional inspection at least once a year can help identify early signs of trouble, such as sediment buildup, leaks, or corrosion. This proactive approach allows for minor repairs that prevent larger, more costly issues down the road.

Sediment buildup is one of the most common causes of water heater failure. Minerals in the water, such as calcium and magnesium, settle at the bottom of the tank, reducing heating efficiency and potentially damaging the tank. Flushing the water heater once or twice a year helps remove sediment and improves the heater’s efficiency. This process involves draining a portion of the water from the tank and refilling it to clear out debris.

The anode rod is a critical component of your water heater, designed to prevent tank corrosion by attracting corrosive elements in the water. Over time, the rod corrodes instead of the tank, protecting it from rust. Regularly checking and replacing the anode rod when necessary (every 3-5 years, depending on water quality) can extend the life of your water heater and prevent leaks.

Setting the water heater to a temperature that is too high can accelerate wear on the tank and increase the risk of scalding. The Department of Energy recommends a temperature setting of 120 degrees Fahrenheit to balance energy efficiency and safety. This temperature is sufficient for most household needs and helps prevent excessive strain on the system.

If your home has hard water, installing a water softener can help protect your water heater from the damaging effects of mineral buildup. Hard water contains high levels of minerals that accumulate over time and contribute to sediment buildup, reducing the heater’s efficiency and lifespan. A water softener treats the water before it enters your plumbing system, minimizing sediment and extending the life of your water heater.
