1. If you don't turn off the faucet during the water cut-off, turn off the faucet after the water comes in, let out 2 to 3 liters of accumulated water, and then put the basin of water for a while to see if the water quality becomes clear. If it is clear, it means that tap water can be used. If it is still turbid, it may be that the tap water pipe is polluted and needs to contact the relevant departments for handling.
2. If the tap is turned off when the water is stopped, but the tap water is still turbid, it may be that the rust and impurities in the tap water pipe have been released, and it will take some time to make the water clean. You can use some purifiers or screens to filter out some impurities.
3. If the tap water is still turbid or smelly, it is recommended to use disinfectant for disinfection. Disinfectants such as bleaching powder or chlorine dioxide can be used according to the proportion in the instructions. After disinfection, wait for a period of time to let the tap water flow clean again.
