Frequently Asked Questions

All water supplied to Wheaton customers meets or exceeds state and federal regulations for drinking water. The city collects 60 bacteriological samples monthly as well as numerous other samples required by the Safe Drinking Water Act. Results of some of these samples are reported in the annual Water Quality Report, which is published on the City's website every June.

Most low pressure complaints are related to out-of-service water softeners. If you are no longer using your water softener, it needs to be bypassed with valves or removed from the system. Unplugging the softener doesn’t eliminate water from passing through it, and it can reduce pressure. Normal water pressure in Wheaton varies between 50 and 75 pounds per square inch. Contact us at 630-260-2090 for more information.

Most high bills are caused by leaking toilets. Leaking faucets, malfunctioning water softeners and water-powered sump pumps also are seen as the cause of high bills. Plumbing fixtures should be checked regularly. Toilet flush valves can be checked by adding food coloring to the flush tank, and if the color enters the bowl without flushing, the flapper valve is probably leaking.

Wheaton water, which uses Lake Michigan as its source, has a hardness of six to eight grains per gallon. Contact us at 630-260-2090 for more information.

This is caused by increased levels of dissolved oxygen in colder water. Lake water in the winter months can reach temperatures as low as the mid 30s. By drawing water in a clear container, you can see the air bubbles rise to the top as it clears. Contact us at 630-260-2090 for more information.

This musty or earthy odor/taste is caused by blue-green algae, which naturally forms in the lake. If you notice this odor, please contact us so we can forward the information to the DuPage Water Commission. The addition of activated carbon at the treatment plant usually remedies this situation.

A cross-connection is a connection between a drinking water pipe and a polluted source. A common example is if you were spraying weed killer on the lawn and the water pressure dropped. The chemical could be sucked back into the water pipes through the hose. Lawn irrigation systems and hot water boilers are examples of cross-connections that require backflow preventors.
