How to Extend the Lifespan of Your Water Heater

Your water heater is one of the hardest-working appliances in your home. It supplies the hot water you rely on for showers, cleaning, cooking, and laundry every day. Because it operates constantly, it deserves regular care and attention. Proper maintenance helps you avoid unexpected failures and ensures your system performs efficiently for years to come.

The average water heater lasts between 8 and 12 years, but consistent maintenance can extend its lifespan significantly. With routine service and a few preventative steps, you can delay replacement costs and get the most value from your investment. MVP Air Conditioning, Heating, Plumbing & Electric is proud to help Kansas City homeowners keep their water heaters running safely and efficiently.

Schedule Regular Water Heater Maintenance

Professional tune-ups are the most effective way to prolong the life of your water heater. Annual inspections help catch small problems before they become costly issues. During a typical maintenance visit, a licensed plumber will test the heating elements, thermostat, and pressure relief valve to ensure your unit operates correctly and safely.

Regular maintenance also improves performance and ensures a steady supply of hot water. Instead of waiting for the tank to reheat between uses, you can enjoy consistent water temperature and pressure whenever you need it.

Flush the Tank Once a Year

Mineral and sediment buildup is one of the most common causes of water heater failure. Over time, these deposits settle at the bottom of the tank and cover the heating elements, forcing them to work harder and use more energy. This not only reduces efficiency but can eventually damage the unit.

Flushing the tank once a year removes sediment and helps your system heat water more efficiently. While some homeowners attempt to do this themselves, it is safest to hire a professional. A licensed plumber has the proper tools and training to perform the job correctly and safely. Our team at MVP Air Conditioning, Heating, Plumbing & Electric provides complete plumbing maintenance services, including professional tank flushing.

Test the Temperature and Pressure Relief Valve

The temperature and pressure relief (T&P) valve is a vital safety feature. It automatically opens if the pressure or temperature inside the tank gets too high, preventing dangerous overpressurization. If this valve becomes stuck or fails to operate, the tank could rupture or, in rare cases, explode.

You should test the T&P valve once per year to ensure it functions properly. The process involves carefully lifting the valve’s lever to release a small amount of water. If you are unsure how to do this, our technicians can test and replace the valve during your routine maintenance visit.

Inspect and Replace the Anode Rod

The anode rod plays a major role in protecting your water heater from rust and corrosion. Made of magnesium, aluminum, or zinc, the anode rod is designed to corrode gradually so the tank lining does not. This “sacrificial” process helps preserve the integrity of your tank and prevents leaks.

Have the anode rod inspected every two to three years. If it is heavily corroded or has worn down to less than half an inch thick, it should be replaced. Ignoring a deteriorated anode rod leaves your tank vulnerable to rust and can shorten its lifespan significantly.

Keep the Temperature Setting at a Safe Level

Setting your water heater temperature too high can accelerate corrosion, waste energy, and increase the risk of scalding. The ideal setting for most homes is 120 degrees Fahrenheit. This temperature is hot enough to kill bacteria but safe for daily use.

If you are unsure how to adjust your water heater’s thermostat, have a professional plumber make the change for you. Incorrect adjustments can lead to overheating or poor performance.

Insulate the Tank and Pipes

Insulating your hot water tank and nearby pipes is a simple and affordable way to reduce energy loss. Proper insulation helps your system retain heat, which means it cycles on less often and experiences less wear. This lowers your energy bills and extends the life of your equipment.

If your tank feels warm to the touch, adding insulation is a good idea. Electric water heaters can safely have the tank and pipes insulated. For gas models, only the pipes should be insulated to avoid fire hazards around the burner area.

Watch for Warning Signs

Pay attention to how your water heater operates. Recognizing early warning signs can prevent major damage or leaks. Common symptoms of trouble include strange noises, inconsistent water temperature, or visible rust.

• Banging, rumbling, or popping noises from the tank
• Cooler water than usual
• Visible rust or corrosion on the tank
• A sulfur or “rotten egg” odor in your hot water
• Water pooling around the base of the unit

If any of these issues appear, contact MVP Air Conditioning, Heating, Plumbing & Electric right away. Fast action can often prevent permanent damage and keep your water heater running safely.
