Why Does My Sump Pump Keep Running?

A professionally installed, well maintained sump pump is the most effective means of preventing basement flooding. Conversely, a malfunctioning sump pump is one of the main causes of flooding, highlighting the need for routine maintenance and efficient repair. There are a number of common problems you may encounter, but one that can cause a lot of damage and should be addressed immediately is constant running.

Read on to learn what causes this issue and what to do if it happens to you.

4 Reasons Your Sump Pump Keeps Running

  • An incorrectly sized sump pump or liner. A sump pump that is too small may run continuously in order to keep up with demand, leading to premature failure. If the pump is sized correctly but the liner itself is too small, it may wear itself out through short-cycling, as it pumps the water out of your home at an elevated rate before the liner has a chance to refill.
  • Continual flooding. A high water table, or underground water source can cause the unit to work around the clock to clear the water. In this case, raising the sump pump may help, without compromising the integrity of the system.
  • A stuck switch. Sump pump operation is determined by a float switch, which turns the unit on and off as needed. Once the water level in the sump pit rises to a pre-determined height, the pump turns on, but a number of issues can cause the unit to continue running long after water levels have returned to normal. Most commonly this occurs when the switch becomes clogged, jammed, or tangled, requiring repair or replacement.
  • Valve issues. The check valve is strategically located along the water discharge line, to ensure the water being pumped out of your home does not re-enter the sump pit. If it is missing, or malfunctioning, anywhere from one, to two-thirds of the discharged water will return to the pit, and the sump pump will run continuously in an effort to remove it.
