How to Maintain an Electric Water Heater

1. Regularly flush the tank

Over time, sediment and mineral buildup can accumulate in the bottom of the tank, which can reduce the efficiency of your electric water heater. To prevent this, flush the tank every six months to a year. Turn off the power and cold water supply, then attach a hose to the drain valve and drain the tank. This will remove any sediment and mineral buildup that has accumulated.

2. Check the anode rod

The anode rod is a component that attracts corrosive elements in the water, which prevents the tank from rusting. Over time, the anode rod will corrode and need to be replaced. Check the rod every two years and replace it if it is more than 50% corroded.

3. Test the pressure relief valve

The pressure relief valve is a safety feature that releases pressure from the tank if it becomes too high. To ensure that it is working correctly, test the valve every six months. Turn off the power and cold water supply, then lift the valve’s lever to release some water. If water doesn’t flow, or it doesn’t stop when you release the lever, replace the valve.

4. Insulate the tank

Insulating the tank can help it maintain its heat and reduce energy costs. You can purchase an insulation blanket from a hardware store and wrap it around the tank. Make sure not to cover the top, bottom, or thermostat.

5. Check the thermostat

The thermostat controls the temperature of the water in the tank. Check it every six months to make sure it is set to the correct temperature, usually between 120- and 140 degrees Fahrenheit. If it is not, adjust it accordingly.

6. Check the electrical connections

Make sure to check the electrical connections to your electric water heater to ensure that they are tight and secure. Loose connections can cause the heater to malfunction or fail.

7. Regularly check for leaks

Leaks can cause damage to your home and lead to costly repairs. Regularly check for leaks around the heater, as well as around the plumbing connections and valves.

In conclusion, maintaining an electric water heater is crucial to ensure that it works efficiently and lasts a long time. By following these tips, you can prevent problems and prolong the life of your electric water heater. Regular maintenance can also help you save money on energy costs and prevent costly repairs. If you are unsure about any aspect of maintaining your electric water heater, consult a professional plumber.
