Regular water heater maintenance can extend the life of your unit, improve energy efficiency, and help you avoid unexpected breakdowns. Whether you have a traditional tank-style or a tankless system, basic upkeep is essential.
Start by checking the temperature setting. For safety and efficiency, it should be set to around 120°F. This prevents scalding and reduces energy consumption.
Next, flush the tank annually if you have a standard water heater. Over time, sediment builds up inside the tank, which can reduce efficiency and even damage the heating element. To flush, turn off the heater, connect a hose to the drain valve, and empty the water until it runs clear.
Inspect the anode rod every 2–3 years. This metal rod attracts corrosion, protecting the tank itself. If the rod is worn down, replace it to prevent rust and leaks.
Also, check for leaks and corrosion around the base of the unit and fittings. Even small leaks can cause water damage and signal internal problems. For gas water heaters, inspect the venting for blockages or damage and ensure the flame is blue, not yellow, which indicates proper combustion.
Finally, test the pressure relief valve by lifting the lever and allowing it to snap back. A burst of water should come out—if not, the valve may need replacement.
Routine maintenance takes just a little effort but can save money and trouble in the long run. When in doubt, consult your owner’s manual or hire a professional.
