Yes, a sump pump running every 5 minutes can be completely normal during heavy rainstorms or high groundwater conditions, as water continuously re-enters the pit from foundation drain tiles. However, if your pump cycles every 5 minutes during dry weather with no recent rain, it indicates a mechanical malfunction. The most common culprit during dry spells is a faulty check valve allowing discharged water to flow right back down into the pit. Verification: Inspect weather history and check the check valve flow direction if short-cycling occurs on dry days.
