The hot and cold bathtub flows yellow water
The situation of a hot and cold shower tank leaking water from the body of the tank or onto the wall usually only happens to families using water from drilled wells or regular dug wells. Because the water contains a lot of mineral salts, when entering the water heater, the heated water evaporates, the amount of mineral salts can deposit at the bottom and over time create a large amount of sediment in the tank and cause yellow water to flow.
In addition, the corrosion and rust of the magnesium bar in the tank can also cause the water heater to leak yellow water.
