Homes with a high water table depend on the sump pump every spring. When snowmelt and April rain push groundwater up, a pump can cycle every few minutes for weeks, and any failure floods the basement within hours.
Why sump pumps fail
- Power outages during the same storms that raise the groundwater
- A float switch stuck against the side of the pit
- A worn motor that finally burns out after years of spring duty
- A frozen or clogged discharge pipe that sends water back into the pit
- A pump too small for the inflow after a wet season
