Water Heater Maintenance - The Water Heater Sacrificial Anode Rod
When you do this, it is a great time to check the sacrificial anode rod inside the water heater. In the typical water heater, the anode rod access is at the top of the heater. You will need a large adjustable wrench to unscrew the rod and pull it out for inspection. Make sure the water heater is off. Close the cold water supply, and if it is there, close, the hot water valve also. By closing the hot water valve to the water heater, you will drain the water out of the hot water supply line going to the hot water faucets in the house. Some water heaters do not have a valve on the hot water supply going to the faucets.
In this case, make sure all the hot water faucets are securely closed to prevent the water from draining out of the hot water line. At the bottom of the water heater, there is a drain valve. Carefully drain open this drain valve. Make sure there is a safe place to drain the water heater. You may need a water hose in some cases, depending on where the water heater is and if a drain is readily available near the water heater. Make sure the drain is lower than the water heater, especially if using a water hose.
Water Heater Maintenance | Conclusion
If you cannot find the anode rod or you can’t get it lose, then you will still need to drain the tank down. If this is the case, then you need to open up a hot water faucet. That will facilitate a flow so the water heater can drain completely. Before closing the valve after the water heater is drained, open the cold water valve to flush all the sediments from the tank completely. Finish draining the tank by thoroughly flushing it with the cold water valve. Again, if you weren’t able to check the anode rod, you may want to give a plumber a call to have them check the anode rod. It is necessary to have a good anode rod in the tank to extend the life of the water heater.
