Frequently Asked Questions About What to Do After a Drinking Water Advisory
When I turn on the faucet, the water sputters. Why?
- You have air in your lines. Turn on your tap slowly and run the water until the sputtering stops.
The water is discolored. What should I do?
- Flush water pipes by running the water until it is clear.
- Do not wash clothes if the water is discolored. Wait until the water runs clear at the tap. Wash a load of dark clothes first.
Why does my water have a strong smell?
- The smell is probably chlorine. Often, water systems will increase chlorine levels to disinfect the pipes.
What should I do if my water pressure is low?
- Check the faucet screens for trapped particles. Remove the screens and clean out any particles. Put the screens back on the faucet.
Do I need to clean out my faucets?
- Yes. You should flush your faucets after the drinking water advisory.
- Turn on the main water valve.
- Turn on the cold water tap at all faucets and run the water until you feel a change in temperature (i.e. the water gets noticeably colder). This may take several minutes. Begin with the faucet that is highest up in your home or building and then open the other faucets one at a time moving from the highest floor to the lowest.
Do I need to clean appliances?
- Yes. Read the owner’s manual for directions to clean appliances such as water softeners and filter units.

- Throw out ice.
- Flush the water dispenser for 3 to 5 minutes.
- Run the ice maker for 1 hour.

I have a water treatment unit for the house. Does it need special care?
