Plumbing conditions in Illinois
Illinois has cold winters with lake-effect snow near Chicago, hot humid summers and strong spring storms. Large stocks of older brick bungalows and two-flats with basements, and a combined sewer system in Chicago that backs up in heavy rain.
Deep winter freezes are routine in Illinois. Pipes in exterior walls, crawl spaces, garages and unheated basements can freeze and split, and the leak often starts only when the ice thaws. Insulating exposed lines, keeping heat on in vacant homes and knowing where the main shutoff is are the best protection.
Much of Illinois has hard water. Scale builds up in water heaters and fixtures over time, which shows up as popping noises in the tank, weak shower flow and crusty aerators.

Cities we serve in Illinois
Each city page covers local conditions. Towns without a page are served too.
Chicago, IL
Cook County
Chicago's combined sewer system can back up into basements in heavy storms, its bungalows and two-flats often have old cast-iron drains, and the city has more lead service lines than any other US city.
Aurora, IL
Kane County
Aurora sits on the Fox River, and its mix of older downtown homes and newer subdivisions with basements makes sump pumps and backwater valves important.
Naperville, IL
DuPage County
Naperville's large suburban homes nearly all have finished basements, so a failed sump pump during spring storms is one of the most costly calls.
Springfield, IL
Sangamon County
Springfield's older homes near downtown have basements, clay sewer laterals and very hard water that scales water heaters.
Peoria, IL
Peoria County
Peoria's hillside neighborhoods along the Illinois River have older homes with basements that take on water during spring rains and river rises.
