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 for clarity by running cold water for a few minutes allowing new water to work its way into your pipes. If not, wait a few more minutes and check again. We recommend using a tub or outside faucet to clear the line. In some cases, 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.
