Keeping your water heater in top shape not only extends its lifespan but also ensures energy efficiency and reliable hot water when you need it. Whether you have a tank or a tankless unit, regular maintenance is essential.
Start by checking the temperature setting on your water heater. Ideally, it should be set to 120°F to prevent scalding and reduce energy use. For tank-style heaters, sediment buildup is a common issue that reduces efficiency and damages the tank. Once or twice a year, drain a few gallons from the tank using the drain valve to flush out sediment. If the water is especially cloudy or gritty, a full flush might be necessary.
Inspect the anode rod every 2–3 years. This metal rod attracts corrosive elements and helps prevent rust inside the tank. If it’s heavily corroded or worn down, replace it to protect the tank’s interior.
Check for leaks around the base of the heater, pressure relief valve, and connections. Any moisture may signal a developing problem. Also, test the temperature and pressure (T&P) relief valve by lifting its lever and letting some water out. It should flow freely and stop completely when closed.
For gas heaters, inspect the burner and pilot light. Clear away dust or debris, and ensure the flame burns blue (not yellow). Tankless models need annual descaling to remove mineral deposits, especially in hard water areas.
With these simple steps, you can keep your water heater running efficiently and avoid costly repairs.
