Sump Pump Repair and Installation in Chicago, IL
Chicago basements often rely on two different pumps: a sump pump that removes groundwater from the drain tile, and an ejector pump that lifts sewage from below-grade bathrooms. Both fail most often during storms, when they run hardest and the power is most likely to go out. A battery backup is worth having on a sump pump.

What is different about sump pump repair and installation in Chicago?
Knowing which pit is which matters when you call. A sump pit takes clear groundwater and usually has an open or loosely covered top. An ejector pit handles waste, is sealed with a bolted lid and vent pipe, and should not smell. A plumber needs to know which one has stopped, because the parts, the urgency and the cleanup are different.
Homes that have been converted to overhead sewers depend entirely on the ejector pump for basement fixtures, so a failed pump means no basement bathroom or laundry until it is replaced. For sump pumps, test before the spring rains by filling the pit with a bucket, and check that the discharge line outside is clear.

Sump and ejector pump failures
Homes with below-grade bathrooms or drain tile depend on pumps that fail most often during storms, when the power also goes out. A battery backup is worth having.
What to check and ask before work starts in Chicago
- Tell the plumber whether the problem is in the sump pit or the sealed ejector pit
- Ask whether a battery backup or high-water alarm can be added to your pit
- Ask where the sump discharge goes and whether that complies with city rules
- Ask how old the pump is and what its expected service life is
Licensing and permits for sump pump repair and installation in Chicago
Chicago adopts and enforces its own plumbing code, which has historically been stricter about pipe materials than the codes used in most suburbs, and plumbers working in the city must hold a City of Chicago plumbing license. Permits come from the Department of Buildings. Ask for the license number, and ask whether the materials quoted are approved for use in the city.
Keystream Plumbing is a referral service. We do not perform plumbing work or hold a contractor license. The independent plumber you are connected with is responsible for licensing, permits and the work itself.

Sump Pump Repair and Installation questions from Chicago
What is the difference between a sump pump and an ejector pump?
A sump pump moves groundwater collected by drain tile out of the basement. An ejector pump moves wastewater from basement toilets, sinks and laundry up to the sewer line. Many Chicago basements have both, in separate pits.
Why does my sump pump fail during storms?
Storms are when the pump runs almost continuously, which is when a worn motor or stuck float gives out, and storms also cause power outages. A battery backup pump and a yearly test are the practical protections.
