Stuck Float Switch or Constant Running
Tethered float switches can catch against the side of a narrow sump liner, leaving the pump either unable to turn on when water rises or running dry until the motor burns out.
Sump Pump & Backup Guide
Sump Pump Failure & Battery Backups
In South Bend, a sump pump is tested hardest during severe thunderstorms and rapid spring snowmelt—the exact moments when power outages and mechanical overload happen. We connect homeowners with licensed local waterproofing specialists who inspect and upgrade sump basins before flooding starts.
Warning Signs Your Sump Pump Is Failing
Catching a worn switch, clogged impeller, or frozen discharge pipe early prevents an overflowing sump pit.
Short-Cycling Every Few Seconds
If the pump kicks on and shuts off repeatedly, the check valve on the discharge pipe may have failed—allowing pumped water in the vertical pipe to fall right back into the basin—or the basin may be undersized.
Grinding Noises or Age Over 7–10 Years
Rattling or grinding sounds point to a damaged impeller or worn bearings caused by silt or gravel entering an unsealed pit. Pumps older than 7 to 10 years should be evaluated before spring thaw.
Frozen or Blocked Exterior Discharge Lines
During northern Indiana freezes, an exterior discharge line without an anti-freeze relief gap or proper downhill pitch can ice over, blocking water from leaving the basement.
Why Battery Backup Sump Pumps Matter in Michiana
A standard primary sump pump runs on 120-volt household electricity. When a spring squall or winter ice storm knocks out grid power—or trips the basement GFCI breaker—groundwater continues flowing into the perimeter drain tile. Without a backup pump, a pit in a high-water-table neighborhood like Keller Park or River Park can overflow in less than an hour.
A dedicated battery backup system mounts a secondary high-output DC pump slightly above the primary pump inside a sealed basin, paired with a smart charging controller and deep-cycle maintenance-free battery. If power drops or if heavy inflow exceeds the primary pump's capacity, the backup pump activates automatically and sounds an alert.

Sump Pump & Battery Backup FAQs
How long do primary sump pumps typically last?
Most submersible sump pumps last 7 to 10 years depending on groundwater volume and how often the float switch cycles during spring thaws and heavy rain.
What does a battery backup sump pump do?
A battery backup system includes a secondary DC pump and deep-cycle battery in the sump basin that activates automatically if grid power fails or if the primary pump cannot keep up with inflow.
