After a water main break repair is completed in your area, flush your lines using the following steps. Run all cold water faucets for five minutes. Turn off your faucets in reverse order, from lowest to highest. You should also flush your refrigerator’s water lines.
Flushing your water lines lowers the risk of potential contamination that is created whenever a water main is depressurized because of a break. This is particularly important for people who have special health concerns because their immunity is compromised.
When water systems lose pressure there is an increased risk of contamination. Therefore, the WSSC recommends if you live in the affected area:
WSSC asks customers who were under the Boil Water Advisory or who have experienced a water service disruption due to a water main break to take a few precautions.
WSSC recommends you flush the cold water lines you use in your home or business. We recommend you flush your taps as a precaution because of an increase in the number of water main breaks in our aging infrastructure. It will cost you just pennies per faucet to take this important step.
We suggest running all cold water taps for five minutes. If you have a single-lever faucet, set it to run the cold water. Begin with the highest faucet in your home or business and then open the other faucets one at a time, moving from your highest floor to your lowest.
Customers and businesses should also dispose of any ice made since the precautionary Boil Water Advisory. The next three batches of ice should also be thrown out. Ice maker containers should be wiped clean with a solution of two tablespoons bleach to one gallon of water.
If you still experience problems after performing the above procedures, or if you have any questions, please contact our Customer Emergency Call Center 24 hours a day, seven days a week at: (301)-206-4002, 1-800-828-6439 or TTY (301)-206-8345.
