Do gas water tanks have anode rods?
Inside the Tank In glass-lined tanks, there will be a metal rod in the tank, usually magnesium or aluminum, called a sacrificial anode. Some models do not have a separate anode rod but instead have a hot water outlet pipe that is coated with magnesium or aluminum to serve the function of an anode.
What happens if anode rod goes bad?
A bad anode rod can cause discolored water, a rotten egg smell, air in the lines and intermittent hot water. The anode rod protects the tank of electric water heaters & signs it should be replaced are a rotten egg smell, no heat & strange sounds.
Can a side mounted anode rod be removed from a water heater?
Drain only about 10% of the water out of the tank. If you have a side mounted anode rod, you’ll need to drain more. Since many old rods are difficult to remove, having the extra weight in the tank will prevent the entire water heater from rotating as you attempt to loosen the rod.
Can a Liquid Wrench be used to remove anode rod?
Tightening the anode rod slightly will help break the threads loose, making removal easier. Never use penetrating fluids such as Liquid Wrench on water heater components, as these fluids could contaminate your hot water supply.

Why are magnesium anode rods used in water heaters?
Do not allow the water heater to turn or twist while doing so. Anode rods are made of either aluminum or magnesium. If you ask most professional plumbers, they’ll tell you a magnesium anode rod is preferred simply because it produces a stronger current than aluminum types. This in turn allows it to do a better job of fighting off tank corrosion.
Where can I find information on powered anodes in water heaters?
Also, look up the National Association of Corrosion Engineers, which is a good source of information. Interestingly, one of the biggest water heater manufacturers uses powered anodes in its high efficiency commercial heaters, high efficiency residential gas heater and residential heat pump water heaters.
