Sump Pump Running Constantly in Chicago, Illinois

Sump Pump Running Constantly in Chicago — What to Expect

A sump pump that runs without stopping is on a fast path to motor burnout — most residential pumps aren't designed for more than 7–10 hours of continuous operation. If your Chicago pump is running constantly, act quickly.

The most common cause is a stuck float switch that's telling the pump the water level is always high. Remove the pump from the pit (or reach in carefully) and check that the float arm or ball moves freely. If it's tangled on the discharge pipe or pump housing, you may be able to fix it yourself. If the float is working correctly but the pump keeps running, the issue is likely a failed check valve allowing pumped water to flow back into the pit — creating an endless cycle.

High water table is another cause common in certain Chicago neighborhoods, particularly near rivers, lakes, or low-lying areas. If your pit refills within seconds of the pump running, you may need a larger pump or a second pump system. A Chicago waterproofing contractor can assess your drainage situation and recommend the right solution.
