Flush all taps when the order is lifted
When flushing, it is important to follow the instructions provided. Flush your household and building water lines, including:
- Interior and exterior faucets,
- Water/ice dispensers,
- Water treatment units, etc.
- Water heaters may need to be flushed to remove any contaminated water.
- Some types of water treatment devices may need to be disinfected or replaced before being used. Check with the manufacturer for details.
Detailed guidance for what to do after a boil order ends follows.
Cold Water Faucets: Run until the water feels cold, one minute or more, before drinking, brushing your teeth, or using for food preparation. If you have a single-lever faucet, set it to run the cold water first.
Hot Water Faucets: To clear hot-water pipes and water heaters of untreated water, change all faucets to hot water and flush for at least:
- 15 minutes for a typical household 40-gallon hot-water tank
- 30 minutes for an 80-gallon hot water tank or larger
Hot water is then safe to use for washing hands, dishes, pots and pans, etc. Never use water from the hot faucet for drinking, rinsing your mouth, or cooking.
Dishwashers: After flushing hot water pipes and water heaters, run the dishwasher empty one time.
Humidifiers: Discard any water used in humidifiers, Continuous Positive Airway Pressure (CPAP) machines, oral, medical or health care devices. Rinse the device with clean water.
Food and baby formula: Discard baby formula and other foods prepared with water on the day or days of the boil order. (If unsure of the dates, contact your water department.)
Refrigerator water-dispensing machine: Flush with at least one quarter of water. If unsure of your dispenser's capacity, refer to manufacturer specifications.
Ice cubes: Empty automatic ice dispensers of ice made during the boil order and run through a 24-hour cycle. Discard this ice to assure purging of the icemaker's water supply line.
Note: After a boil order, the local water department may flush hydrants. As a result of flushing both hydrants and home water lines, some customers may experience a lack of water pressure and/or discolored water. This is an expected result and does not pose an immediate health risk. Contact your local water department if you have any questions.
