Most homeowners are unaware that the majority of water heaters have a magnesium bar called an anode rod installed in their heater. It can be identified by looking at the top of the water heater for a hexagonal fitting. If you don't have this hexagonal fitting on the top of your water heater, make sure that the next water heater does because it can potentially double the useful life of your water heater saving you a lot of cash. The replacement of the anode rod is fairly simple and straightforward. Turn off the cold water supply to your water heater first or turn off your gas or electricity, whichever is connected to the water heater. You will next need to remove the water heater from the pipes, but be careful since the water pipes may still have hot water in them which is still hot enough to burn you Using a standard garden hose attached to the drain at the bottom of the heater, remove several gallons of water. Remove the anode rod with a pipe wrench or similar tool. Purchase a comparable anode rod at your local hardware store, home center or plumbing supply house. The water lodged inside the junk becomes hot enough to create steam bubbles, which eventually rise and turn back into hot water. Nearly all hot water heaters have a drain near the bottom of the tank. Before making repairs, fill the tub with water, which will weigh it down slightly. Once completed, you can remove the water heater and dispose of it. Connect the new water heater to the same connections as the old one, and connect the third pipe to the main water line. If the cold water turns hot and your hot water never warms, you will need to switch the pipes. Next, you must locate the relief valve on the new hot water heater. Finally, connect the new hot water heater to the power.
