Hydrant Flushing

Hydrant flushing is an essential part of our annual system maintenance program

Each year, Pennsylvania American Water flushes the pipes in its water distribution system. This is an essential part of our system maintenance program, which helps us to continue to provide you with high-quality water service. Although we’ve been carrying out this maintenance program for decades, we do receive questions from time to time about why we flush.

Why flushing is important

Flushing our system helps to clean out any buildup of mineral deposits and sediment inside the pipes. These harmless deposits can occur when there is a reduced water demand. We also flush our hydrants to make sure they are operational and to check fire flows in our system.

How we flush our pipelines

Flushing involves simultaneously opening fire hydrants in a specific area to create increased water flows. When crews are in your area, you may notice a drop in water pressure or discolored water. Discolored water may occur because the sediment in water mains gets stirred up when the fire hydrants are used and when the flow of water in mains is changed. This is normal. If this happens, it is not harmful. Simply let your water run until it is clear.

What to do to prepare for flushing in your neighborhood

  • Draw water for cooking ahead of time.
  • Store a large bottle of water in the refrigerator for drinking.
  • Check for discolored water before using the washing machine or dishwasher

Note: If your laundry becomes stained, DO NOT USE BLEACH AND DO NOT PUT YOUR LAUNDRY IN THE DRYER. Rewash clothes immediately using more detergent or a heavy duty detergent and add a rust remover. Most rust removers can also be used on stained fixtures.
