Your water heater works behind the scenes every day to power showers, laundry, dishwashing, and more. Like any major appliance, though, it has a limited lifespan. Tank water heaters typically last 8–12 years, while tankless units can serve you for 15–20 years. With the right care, you can stretch their years of useful service while avoiding untimely breakdowns. Here are some proven steps to keep your water heater running at its best.
Flush the Tank Regularly
Over time, minerals in your water settle at the bottom of the tank, forming sediment. This buildup is corrosive and forces your water heater to work harder. Flushing the tank once a year removes sediment and allows the system to heat water more effectively. This one step alone can help prevent repairs and extend the life of your unit.
Inspect the Anode Rod
Inside your water heater is a metal rod designed to attract corrosive elements in the water. Known as the anode rod, it protects the lining of the tank by sacrificing itself to rust first. Once the anode rod wears out, your tank is at increased risk of corrosion and leaks. Have it checked every couple of years – or look at yourself – and replace it when needed. It’s a simple fix that can prevent early system failure.
Set the Right Temperature
Many water heaters are preset to 140°F, but in most households, 120°F is more than adequate. Lowering the temperature reduces wear on the system, reduces energy use, slows mineral buildup, and makes your home safer by reducing the risk of scalding.
Add Insulation
Wrapping your water heater in an insulating blanket and insulating hot water pipes can cut down on heat loss. This helps your system work more efficiently, can add years to its service life, and reduces energy bills.
Pay Attention to Warning Signs
Don’t ignore signs that your water heater may be struggling. Rust-colored water, loud popping noises, an inconsistent supply of hot water, or moisture around the base of the unit are all red flags. Addressing these issues early can mean the difference between a simple repair and a costly replacement.
Schedule Professional Maintenance
Even with regular DIY care, professional attention can do even more to keep your water heater working to maximum effectiveness. That’s why we recommend an annual whole-house plumbing inspection, one that will include a comprehensive inspection of your water heater. In the process, we’ll check the anode rod, safety valves, test performance, and catch small problems before they can grow and cause more system damage.
