Basements & sump pumps in Chicago, IL
A sump pump keeps groundwater from rising into a basement or crawl space. Most last about 7 to 10 years. Replacing an aging pump before storm season, and adding a battery backup or alarm, is far cheaper than cleaning up a flooded basement.

Local conditions
Basements & sump pumps in Chicago: what's different
Chicago's combined sewers can back up during heavy summer storms and push water into basements. Even with the Deep Tunnel storing stormwater, intense storms still overwhelm local sewers, which is why overhead sewers, backwater valves and sump pumps are common Chicago upgrades.
Bungalows, two-flats and greystones in neighborhoods like Logan Square and Pilsen have basements with floor drains tied to the main sewer. Knowing whether water comes from groundwater or the sewer decides whether a sump pump or a backwater valve is the right protection.
