Look at the tap water you use. Due to over-exploitation of groundwater, some cities have switched to surface water. In order to ensure the water quality, the water supply company disinfected it, and the smell of disinfected water would be very strong. It is also related to the aging of water supply pipes, especially the old iron pipes, which cause water pollution due to internal corrosion (even if you use your own well water, the water quality will be not very good because of the drop of water level). Better install a water purifier. Drink it and rest assured!
