Breaks in water mains and fire hydrant flushing cause the water’s velocity to increase dramatically. When this flow increases, rust particles from within the mains can be picked up and carried by the water into your house, thus discoloring the water.
If your water is discolored, please be assured it is safe to drink. However, we do not recommend doing laundry in it until it clears up, as clothes could become stained. Generally, if you let the water run for 5-15 minutes, it will clear up on its own.
