5 Helpful Water Heater Maintenance Tips to Extend Its Lifespan

Regardless of the type of water heater you use in your Indianapolis home, taking proactive steps to maintain it can help your system last longer and prevent unexpected cold showers. At Mister Water Heater, with over 60 years of experience in water heater service, here are five straightforward maintenance tips we’ve found that can help you get the most out of your unit.

1. Regular Flushing Prevents Buildup

Every water heater is susceptible to sediment buildup, especially in areas with hard water. Once or twice a year, draining a few gallons of water from the tank (or flushing your tankless water heater, following the manufacturer's instructions) helps keep the heating elements working efficiently and prevents corrosion. Frequent flushing also reduces noise and can improve hot water recovery times.

2. Check the Temperature Setting

Setting your water heater’s thermostat to 120°F not only helps cut energy bills but also protects your system from overheating. It’s a simple adjustment that works for electric, gas, tankless, and hybrid water heaters.

3. Inspect and Replace the Anode Rod

This simple metal rod inside your tank attracts minerals that would otherwise erode the tank lining. If the rod appears thin or coated, which typically occurs every 2-3 years, replacing it can significantly extend the life of your water heater.

4. Look Out for Leaks and Rust

Regularly inspect the base, connections, and valves for signs of moisture or rust. An early catch means you'll need a minor repair rather than a full replacement.

5. Don’t Forget Professional Maintenance
