Anode rods are used in RV and home hot water heaters.
Aluminum tanks are not required to have an anode rod where steel tanks usually are.
the copper cylinder(cathode) and iron rod(anode)
turn off water on cold inlet to heater. attach water hose to drain hosebib on front bottom of heater. turn on hosebib, then either open cold water flex line to create a vacuum so the tank will drain. then the anode rod will be the plug style behind the vent or sometimes in front of the vent. if no plug is found the anode rod is attached to the hot nipple usually found on ( a.o smith, bradeford whites and some rheems). remove anode you will notice if its corroded then replace same way anode was removed.
Sacrificial anode.
Anode means A metal rod inserted into the air water heater to extend the lifeof the tank
The anode rod in a water heater helps prevent corrosion by attracting corrosive elements in the water, protecting the tank from rust and extending the life of the water heater.
The anode rod in a water heater should be replaced every 3-5 years to maintain the efficiency and longevity of the water heater.

The water heater anode rod should be replaced every 3-5 years to maintain the efficiency and longevity of the water heater.
The purpose of a well water anode rod is to protect the water heater from corrosion by attracting corrosive elements in the water. The anode rod sacrifices itself by corroding instead of the water heater tank, extending the life of the water heater.
Follow Some steps for remove magnesium rod in hot water heater.1 Turn off water and fuel supply (gas or electricity) to water heater.2 Partially drain the water heater.3 Locate the anode rod on the water heater; if necessary, unscrew and lift off the cover from the top of the heater.4 Use a ratchet wrench and 1 1/16-inch deep socket to unscrew the anode rod from the heater.5 If the anode rod won't budge, slip a steel pipe onto ratchet wrench handle for extra leverage.6 Lift out and discard the old anode rod.7 Wrap Teflon tape around threads of new anode rod; insert anode rod into water heater and tighten with 1 1/16-inch socket.8 If limited space above the heater prevents the installation of a standard anode rod, install a collapsible type.9 Turn on the water and fuel supply to the water heater.alliedallcityinc.com
The symptoms of a bad anode rod in a water heater include rusty or discolored water, a sulfur-like smell in the water, and a decrease in hot water supply.
For well water, it is recommended to use a magnesium anode rod instead of aluminum or zinc rods. Magnesium anode rods are better suited for well water with higher levels of minerals, as they are more effective at protecting the water heater tank from corrosion.
