Frequently Asked Questions

What do I do if my water pressure is low?
You should run water from the outside faucet to check the pressure. If the pressure is low then check the screens at faucets and water softener filters. If necessary contact the City of Crest Hill during business hours.

What do I do if my water is discolored or has an odor?
If the water is clear from the outside faucet then the hot water heater needs to be flushed and odor should stop once this has been done. If the water is not clear from the outside faucet, then do not run the water for three (3) hours. After three hours, flush the water throughout your house.

At what point is a water leak the City of Crest Hill's responsibility?
Any leak between the curb stop (valve) and the home is the responsibility of the homeowner.


Q: What does this Boil Order mean?

A: There was an interruption in the system on your area and due to the possibility of unsafe water, and the city has decided to order a PRECAUTIONARY boil order. Please boil all DRINKING water, this includes water for drinking, making ice cubes, washing foods, brushing teeth or any other activity involving consumption of water. Water should be brought to a full, rolling boil for at least 5 minutes to ensure that it is safe for consumption, once you have boiled the water it may be stored at room temperature or in the refrigerator in a closed container.


Q: Why did this happen?

A: This was due to unforeseen circumstances, we had an interruption in the system and we are doing this a precautionary measure.


Q: How long will the boil order be in effect?

A: I’m sorry but there is no exact time frame right now, as the water has to get tested and the City has to receive the results in order to lift the boil order.


Q: How will I know when the boil order is lifted?

A: Just as they door hangers were left to notify you of the PRECAUTIONARY boil order, we will place door hangers to notify you that the PRECAUTIONARY boil order has been lifted, those door hangers will be green in color.
