In many cases it is necessary to interrupt water service to homes in the area around a water main break. Unfortunately, interrupting your water service may stir up sediment in the pipe and cause water containing this sediment to enter nearby homes. Also air may get entrapped in the lines. If the water service is interrupted in your neighborhood, you can help in removing the air from the lines and prevent sediment clogs by removing the aerators from sinks and washing machines and running the water for a few minutes to flush your pipes.
