The magnesium rod of the water heater needs to be replaced regularly to ensure its protective effect and the longevity of the water heater. This is because the main function of the magnesium rod is to protect the inner tank and heating tube from being corroded by limescale and impurities. With the increase of use, the magnesium rod will gradually be depleted, and its protective effect will decrease. If the magnesium rod is not replaced for a long time, not only the protective effect will disappear, but also may cause more serious corrosion and damage to the inside of the water heater, shortening the service life of the water heater. Replacing magnesium rods is not complicated, but it is recommended that non-professionals seek professional help to ensure safe operation.

Turn off the power or water source to make sure it's safe.
Drain the water inside the water heater by unscrewing the drain or using a bucket to catch the hot water.
Unscrew the set screws on the bottom of the water heater and gently remove the water heater.
Locate the magnesium rod and unscrew it with a suitable tool (such as a wrench).
Attach the new magnesium rod to make sure the contact is tight.
Re-secure the water heater and make sure all screws are tightened.
Fill up with water and turn the power or water source back on.
The replacement cycle of magnesium rods is generally 2-3 years, and the specific time can be adjusted according to the frequency of use and local water quality. It is recommended to check the condition of the magnesium rod regularly, and if it is found that its consumption is serious or the protective effect is not obvious, it should be replaced in time.
In addition to magnesium rods, other accessories of water heaters such as heating pipes, thermostats, etc. also need to be checked and maintained regularly. For water heaters that have not been used for a long time, it is recommended to conduct a comprehensive inspection before using them to ensure safety.
The magnesium rod of the water heater needs to be replaced regularly to guarantee its protective effect and the service life of the water heater. Replacing magnesium rods is not complicated, but it is recommended that non-professionals seek professional help to ensure safe operation.
