When the system is being flushed, customers may notice a drop in water pressure or experience discolored water. This is a normal part of the process. The company advises customers to let their water run until it is clear.

New York American Water offers its customer the following additional tips:

  • Mark your calendar to be prepared when the company begins flushing the water mains in your neighborhood.

  • Draw water for cooking ahead of time, and store a large bottle of water in the refrigerator for drinking.

  • Check for discolored water before using the washing machine or dishwasher. Wait until the water runs clear at the tap before doing laundry or running the dishwasher.

  • If laundry becomes stained, do not put your laundry in the dryer. Rewash clothes immediately using a heavy duty detergent and add a rust remover. Most rust removers can be used on stained fixtures.

  • In some cases, slight discoloration may linger for a few hours. This discoloration only affects the appearance of the water and does not affect the water quality.

  • If water pressure or water volume seems low after flushing has been complete, check faucet screens for trapped particles.
