Why Does My Sump Pump Keep Turning On and Off?
A sump pump should activate when water reaches a certain level and stop after the basin has been lowered. When the pump turns on and off every few minutes or runs in very short bursts, it may be short cycling.
Frequent cycling can place unnecessary wear on the pump and may signal a problem with the float, check valve, basin, or incoming water.
The Float Switch May Be the Problem
The float switch controls when the sump pump starts and stops. If the float is obstructed, incorrectly positioned, or unable to move freely, the pump may activate before enough water has entered the basin.
Proper float placement and operating range are important for avoiding short cycles.
Water May Be Flowing Back Into the Basin
The check valve helps prevent discharged water from returning after the pump shuts off. If the valve is missing or not working properly, water can flow back into the basin and cause the pump to restart.
A check valve can help reduce short cycling by keeping discharged water from reversing direction.
The Basin or Pump May Be Undersized
A small sump basin may fill quickly and give the pump very little time between cycles. The pump may also cycle frequently when groundwater is entering faster than the system was designed to manage.
A plumber can evaluate the pump, basin, discharge line, and drainage conditions to determine whether the system is properly sized.
