Please use the following guidelines:

Cold Water Faucets

Run all cold water faucets in your home at the same time for five full minutes with the highest water flow possible. Avoid splashing or flooding of the drains. If you have a single-lever faucet, set it to run the cold water first.

Hot Water Faucets

To clear hot-water pipes and your water heater, turn on all hot water faucets (or turn your single-lever faucets to the hot position) and run for a minimum of 15 minutes for a typical household 40-gallon hot-water tank. For an 80-gallon hot water tank or larger, run water for at least 30 minutes. Hot water is then safe to use for washing hands, and for hand-washing of dishes, pots, and pans, etc. Remember, SUB recommends that you never use hot water for cooking or for preparing baby formula. Always start with cold water for these purposes.


After flushing hot water pipes and your water heater, run your empty dishwasher one time.


Change all filters located at the tap or within an appliance.

Refrigerator water dispensers

Water dispensers from refrigerators should be flushed using at least one quart of water. If unsure of your dispenser’s capacity, refer to manufacturer specifications.

Ice cubes

To flush the automatic ice dispensers, make three batches of ice and discard.


Discard any water used in humidifiers, Continuous Positive Airway Pressure (CPAP) devices, and oral, medical, or health care devices. Rinse devices with clean water before using.

Food & Baby Formula

Discard baby formula and other foods prepared with water on the day(s) of the boil water notice.

Water Softeners

Run water softeners through a regeneration cycle. Follow the manufacturer’s guidelines specified in the owner’s manual.
