I live in St Joseph County, Indiana (Walkerton/ North Liberty area). Moved into this property (built in 2022) June 2025. From June through February the sump ran normally — only during heavy rain, cycling for a day or two then stopping. No issues.

March 2026 everything changed. We had a flash flood warning, the pump went from cycling every few hours to every 2-3 minutes and has stayed elevated ever since. Now in mid-May it's still cycling every 3 minutes.

What I've already ruled out and addressed:

• Float is functioning correctly, manually tested
• Check valve is intact and properly installed
• No water meter anomaly — city water leak ruled out
• Discharge pipe is clear — snaked the full corrugated run, no blockage
• Discharge drains to street storm drain, verified no backflow path toward house
• Sump pit inlets (French drain) are actively flowing — confirmed groundwater source, not recirculation
• Installed a battery backup pump as a precaution, and kept a spare pump at hand
• Basement has stayed completely dry throughout

Anyone is dealing with this?

I've asked my neighbor and one told me he got three pumps running the whole season, and the other neighbor said it's abnormal and should be checked.

What do you all think?
