Regular maintenance is essential for keeping your water heater running smoothly and efficiently over time. This includes checking all fittings and valves for tightness; flushing out the hot water system; inspecting the temperature and pressure relief valve; cleaning out any sediment buildup; replacing old gaskets; checking for leaks; and replacing anode rods as necessary (at least once every two years). By doing these things regularly, you can help prevent damage and early failure of components inside your appliance.
