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.
