A sump pump is the one appliance that only matters when it's raining hardest — and that's exactly when a failed one floods the basement. Sump pump service covers the whole system: installing a new pump, repairing a failed float switch or motor, adding a battery backup for the power outages that so often accompany the storms that overwhelm the pit, and making sure the check valve and discharge line actually carry the water away from the Illinois foundation. A pump is a mechanical device with a finite life, so knowing its condition before the next storm is what keeps the basement dry.
Most sump failures trace to a handful of parts. The float switch — which tells the pump to turn on — is the most common failure point, sticking or hanging up so the pump never runs or never stops; the motor burns out from age or from short-cycling; the check valve fails and lets pumped water drain back into the pit; and the discharge line freezes or clogs so the pump runs against a blocked pipe. We test the switch, the motor, and the check valve, size the pump to the pit's inflow, and confirm the discharge runs freely away from the Illinois foundation before we call it done.
The upgrade that saves the most basements is a battery backup, because a primary pump is useless in the power outage that a severe storm so often brings. We install battery-backup and water-powered backup systems that take over automatically when the primary pump loses power or can't keep up, along with high-water alarms that alert you before the pit overflows. Whether it's a failed pump, an aging one you want checked before the season, or a first backup system, we make the Illinois sump system reliable when the Illinois storm actually tests it.
Is it time for sump pump service? The signs
The pump runs constantly or won't stop
A pump that never shuts off has a stuck float switch or is undersized for the inflow, and it will burn out fast. We diagnose and correct it before it fails during a Illinois storm.
A pump that stays silent as the pit fills has a failed float switch, a bad motor, or a tripped circuit. It's the failure that floods a basement, so we test and repair it promptly in the Illinois home.
Water drains back into the pit
If the pit refills right after the pump runs, the check valve has failed and pumped water is draining back. Replacing the check valve stops the short-cycling in the Illinois pit.
The pump is old or you've never tested it
Sump pumps last around 7 to 10 years, and one that's never been checked is a gamble against the next storm. A pre-season test tells you its condition before the Illinois basement depends on it.
No backup for a power outage
A primary pump can't run when the storm knocks out the power, which is when it's needed most. A battery backup keeps the Illinois basement dry through the outage.
The causes we see & fix most
Float switch failure
The float switch that triggers the pump sticks or hangs up on the pit wall, so the pump never runs or never stops. It's the single most common cause of a Illinois sump failure.
Motor burnout
The pump motor wears out with age or burns out from short-cycling against a failed check valve. A burned-out motor is a pump replacement in the Illinois pit.
Failed check valve
The check valve that keeps pumped water from draining back fails, so the pump cycles repeatedly against the returning water. Replacing it stops the short-cycling and saves the Illinois motor.
Clogged or frozen discharge
The discharge line clogs with debris or freezes in winter, so the pump runs against a blocked pipe and can't move water. Clearing and pitching the line keeps the Illinois system flowing.
Power outage during a storm
The severe storms that fill the pit fastest also knock out power, leaving a primary pump dead. Only a battery or water-powered backup keeps the Illinois basement protected through the outage.

Sump Pump Service FAQs
Top questions homeowners searching for Sump Pump Service near me ask us:
Do I need a battery backup?
If a flooded basement would be costly, yes — because the storms that fill the pit fastest often knock out power, leaving a primary pump dead when it's needed most. A battery or water-powered backup takes over automatically in the Illinois home.
Why does my sump pump keep cycling on and off?
Rapid short-cycling usually means a failed check valve letting pumped water drain back into the pit, or a float set too tight. We replace the check valve and adjust the float to stop the cycling and save the Illinois motor.
Why isn't my sump pump turning on?
The usual causes are a stuck float switch, a burned-out motor, or a tripped circuit. We test each, since a hung float is the most common — and the most dangerous, because it lets the Illinois pit overflow silently.
Can you install a sump pump where there isn't one?
Yes — we can core a pit, install the pump, run the discharge to daylight or a storm line, and add a check valve and high-water alarm. We assess the Illinois basement's water problem and size the system to it, serving ZIPs .
How long does a sump pump last?
Most sump pumps last around 7 to 10 years, though a pump that short-cycles or runs constantly wears out sooner. If yours is near that age or has never been tested, we recommend a pre-season check before the next Illinois storm relies on it.
