If the tap water is used during flushing, it could come out full of sediment and discoloration. If you encounter discolored water, shut the water off and wait several minutes. After waiting, check the clarity by running cold water for a few minutes to allow fresh water to work its way into your pipes.
If the water doesn’t clear after a few minutes, turn it off, wait a few more minutes and try running the cold water again. Although unlikely, there may be cases in which you may experience slight discoloration for a few hours. This discoloration only affects the appearance of the water; it does not affect the taste or water quality.
