What's wrong with the water in the water heater?

When the water heater only has overheated but not boiled warm water, the water stays in the water tank for a long time without high-temperature disinfection, and the water in the water tank cannot flow or the water heater has not been used for a long time, resulting in water becoming "stagnant water". A large number of bacteria will be produced, which will make the water stink. Solution of smelly water in water heater: smelly water in water heater can discharge sewage. Turn off the electricity of the water heater first, then unscrew the pressure reducing valve screw on the water heater, and the sewage can be naturally discharged from the air outlet. After all the water is drained, add tap water and drain it. It can be reused after repeated cleaning, so that the newly stored water in the water heater will not stink again. Water heaters must be used frequently and cleaned regularly. When using the water heater, the water temperature and water flow are unstable. When there is abnormal noise, you can find professional electrical maintenance personnel to clean it at home. Because it may be caused by water quality problems or too much scale, timely cleaning can prevent the water in the water heater from stinking. If there is something wrong with the magnesium rod of the water heater, it will also cause the water to stink. Magnesium rod is mainly used to protect the inner container of water heater and prevent corrosion. You can take out the magnesium rod first when it smells. If it is normal after being taken out, it means that it is a problem with the magnesium rod. It is recommended to replace the magnesium rod. When using the water heater, you can first adjust the temperature to the highest, and then use the water in the water tank after high-temperature sterilization.
