Modern water heaters are difficult to repair and don’t require a lot of maintenance. This disadvantage with water heaters today is that they life span of a typical water heater is between 10 and 12 years.
To increase the life of your water heater here are some recommendations:
- Lower the temperature setting on the thermostat to 120° F. This provides sufficient hot water for
most families, reduces the chance of scalding, and decreases wear on your water heater’s tank.
- Corrosion happens faster in hotter water. Your water heater is built with a sacrificial anode that helps protect the steel tank by providing a replaceable component that sacrifices itself to the naturally occurring corrosive compounds in the water. This anode should be replaced periodically.
- Sediment is small particles of debris that settle out on the bottom of your water heater. A drain valve at the bottom of every water heater provides a way to drain sediment from the tank. If your water heater rumbles or makes other noises, you probably have a build-up of sediment in the tank and should consider draining a portion of the water to remove the sediment.
Steps to drain a water heater
- Turn off the water supply shut-off valve. This valve is located on the cold water supply to the water heater.
- Turn the temperature dial to ‘vacation’ mode. This will prevent the burner from actuating while the water heater is draining.
- Attach a garden hose to the drain valve at the bottom of the water heater and direct the hose to a safe location. If you have a floor drain nearby you can drain it there.
- Open up the drain valve and beginning draining the water. If you don’t see any sediment in the water you can stop at any time. If there is sediment in the water continue to drain until the water is clear.
- Close the valve and disconnect the hose.
- Turn the water supply back on
- Turn the temperature dial back to your original setting.
