Water heater maintenance checklist

Water Heater Maintenance

Turn of the water heater
Prevent scalding and other water heater-related injuries by turning off the water heater and allowing the water to cool down overnight before performing the water heater maintenance.
Check the valves and look for possible leaks on pipes and joints
Check the Temperature and Pressure (T&P) relief valve following the manufacturer’s recommendations on its label. Check the water pressure valve and make sure that it shows the recommended water pressure (40-60 psi in the daytime). Tip: apply soapy water on pipes and pipe joints. Observe if bubbles will appear as this is a sign that there's a leak.
Flush any sediment buildup
Connect a hose to the drain valve before you begin draining and flushing out sediment buildup. Eliminating sediment buildup will help with water heating efficiency and prolong the good working condition of the water heater.
Check the anode rod and replace if needed
An anode rod’s purpose is to protect the water heater lining and the inside of a water heater tank from damage and corrosion. Anode rods need to be checked during maintenance to ensure that they have not corroded yet. Depending on factors such as the hardness of the water and how much water goes through the water heater, an anode rod may need to be replaced every 3-5 years.
Refill the water heater tank
Refill the water heater tank by closing the drain valve and opening the cold water supply valve. Open a hot water faucet and let the water out for around 3-5 minutes to make sure that there’s no air remaining in the tank before you turn the water heater back on.
