City lifts boil water advisory; here's now to flush water lines

Hendersonville's water department on Monday afternoon lifted a boil water advisory it had issued Saturday when an 8-inch water main broke.

The outage affected 154 homes in Claremont, Kingcrest and Cobblestone.

Here is information from the city on how to flush water lines:

Customers are advised to "flush" their water lines following the lifting of a boil water advisory in order to clear plumbing of potentially contaminated water. Flushing your household and building water lines includes interior and exterior faucets, showers, water and ice dispensers, water treatment units, etc. Please use the following guidance:

Cold water faucets
Before using the water line for drinking, brushing teeth, making ice cubes, food preparation etc. make sure it is clear from any forms of particulate matter and air (milky coloration). Turn on the cold water tap and let it run until water becomes clear. You should also open all cold-water lines such as fountains, showers and outside water spigots and run them for five to ten minutes.

Hot water faucets
To clear hot-water pipes and water heater, flush the hot water line for a minimum of 15 minutes for a typical household 40-gallon hot-water tank, 30 minutes for an 80-gallon hot water tank or larger. Hot water should be clear of sediment and air before using to wash hands and for hand-washing of dishes, pots and pans, etc.


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

Coffee makers, food dispensers and beverage machines
Flush equipment like food dispensers and beverage machines with clean water and follow the instruction manual on how to disinfect or clean the machine.

Water treatment device

Replace water filters, water cartridges, faucet screens and aerators on all taps used as water
treatment and filtration devices, in accordance with manufacturer recommendations. When in doubt, it is always best to clean, sanitize and disinfect any of these devices before using water again.
