Is the water in the enamel water tank harmful?

In theory, the water in the enamel water tank does not pose a direct threat to the human body because the enamel coating forms a stable protective film on the inner wall of the tank, which can effectively isolate the contact between water and the iron plate, prevent the precipitation of iron ions, and reduce the corrosiveness of water. However, in practical applications, the water quality in enamel water tanks may be affected by external factors, leading to a decrease in water quality and potentially causing harm to human health. For example, long-term storage of tap water in a water tank, or climate change caused by seasonal changes, may promote the precipitation of elements such as iron and rust in the water, thereby deteriorating the water quality. In addition, if the installation of the water tank is not standardized, or if the interior of the water tank is not cleaned and maintained for a long time, it will also affect the water quality to a certain extent.
