Sump pump backup — the difference between a wet-cycle and a finished-basement loss.
A primary sump on grid power is a single point of failure. June storm events in 2017, 2019, and 2022 knocked out Eden Prairie power for 8–36 hours during peak high-water-table conditions. Battery backup, water-powered backup, or generator-tied sump service is non-negotiable on any property within the lake-belt moisture corridor — Bryant, Mitchell, Round, Staring, Red Rock, Anderson, Riley Creek.
The storm that floods the basement is the same storm that takes out the power.
Eden Prairie sits on a lake belt with seasonal water tables that climb to within inches of basement slab in spring melt and after sustained June storm events. The primary sump runs constantly during these events. The same storms that drive the water table also bring down power lines — 2017, 2019, and 2022 each produced 8–36 hour outages across large sections of the city. On a property with $80,000 to $200,000 of finished-basement value (a typical Bearpath, Cedar Forest, Mitchell Lake, or Hennepin Village build), a $600 backup system is the cheapest insurance in the home. We test the primary, log the backup, and recommend in writing.
Six things that go wrong with sump systems.
Each is documented in the photo dossier with severity and a corrective recommendation.
No backup at all
Single primary on grid power. Most common condition we find in Eden Prairie homes 1995 and older. Cheapest fix in the report.
Battery dead or undersized
Backup installed years ago, battery never replaced. We test under load. A backup battery older than 4 years is the most-flagged maintenance defect.
Discharge to grade-fail
Discharge line dumps within 4 ft of foundation, recycling water back into the drain tile. Or freezes solid in February. Re-routed and extended.
Float stuck or tethered
Tether float caught on the discharge pipe or pit wall. Pump doesn't activate or doesn't shut off. Common on older tethered-float configurations.
No high-water alarm
Cellular alarms route to phone. $100–$200 installed. Not a substitute for backup capacity, but a documented complement.
Properly equipped system
Primary + battery backup + alarm. We log the configuration so the next buyer or insurance carrier has documentation.
Three steps. Test the primary. Log the backup.
Controlled fill of the pit
We add water until the float lifts. Primary activates, runs to drawdown, shuts off cleanly. Cycle is photographed and timed.
Type, age, capacity
Battery backup: model, install date, voltage at terminals. Water-powered backup: supply pressure verified. Generator-tied: transfer-switch label noted.
