Your hot water heater plays a vital role in your home, providing warm water for showers, laundry, and dishwashing. Regular maintenance helps extend its lifespan, improve efficiency, and prevent costly repairs.

At Swift Plumbing & Heating, we help homeowners in Bainbridge Island, WA, keep their water heaters in top condition with expert maintenance services. Here are some key preventive maintenance tips to ensure your hot water heater runs smoothly.

Flush the Tank Annually

Sediment and mineral deposits can accumulate inside your water heater tank over time, reducing efficiency and potentially causing damage. Flushing the tank once a year removes these deposits and improves heating performance. To do this, turn off the power or gas supply, attach a hose to the drain valve, and flush the water until it runs clear.

Check the Anode Rod

The anode rod prevents corrosion inside the tank by attracting rust-causing elements. Inspect it every two to three years and replace it if it appears heavily corroded or worn down. A properly functioning anode rod can significantly extend the lifespan of your water heater.

Test the Temperature and Pressure Relief Valve

The temperature and pressure relief (T&P) valve is a crucial safety component that prevents excessive pressure buildup inside the tank. To test it, lift the valve’s handle and allow a small amount of water to flow out. If no water is released or the valve doesn’t close properly, it may need to be replaced.

Insulate the Tank and Pipes

Adding insulation to your water heater and surrounding pipes helps reduce heat loss, improving energy efficiency and lowering standby heat loss. This is particularly beneficial for older water heaters or units located in colder areas.

Set the Temperature to 120°F

Keeping your water heater set at 120°F helps prevent overheating, reduces energy costs, and minimizes the risk of scalding. This temperature is ideal for efficiency and safety.

Look for Signs of Leaks or Corrosion

Regularly inspect your water heater for leaks, rust, or moisture buildup around the base. If you notice any of these issues, schedule a professional inspection as soon as possible to prevent further damage.

Schedule Professional Maintenance

Annual professional inspections help detect potential issues before they turn into costly repairs. A plumber can check internal components, test efficiency, and ensure your water heater is operating safely.

FAQs About Hot Water Heater Maintenance

With regular maintenance, traditional water heaters can last 8 to 12 years, while tankless models can last 20 years or more.

Basic tasks like flushing the tank and checking for leaks can be done at home, but professional inspections ensure deeper maintenance and early problem detection.
