Why does a sump pump run constantly?
A constantly running sump pump usually means water is entering the basin quickly, the float is stuck, the check valve is failing, or discharged water is cycling back toward the foundation. In Minnesota, long rain events and spring thaw can keep a pump busy for hours. The warning sign is when the pump never catches up, sounds strained, or keeps cycling after the storm has passed.
What should you check before calling?
Check whether the float is stuck, whether water is flowing back into the pit after shutoff, and whether the discharge outlet is clear of ice, debris, or pooling water. Do not reach into a live sump pit or handle electrical components if water is present. A few photos and notes about how often the pump cycles can help a provider understand the issue faster.
When should constant running become a quote request?
Request quotes when the pump runs constantly, sounds hot or loud, fails to lower the water level, protects finished space, or has no backup protection. The right fix may be replacement, a check valve, discharge changes, a backup pump, or a broader drainage review.
