Sump Pump Failed? Protect the Basement From Water Damage
A failed sump pump can allow groundwater to rise quickly during storms, snowmelt or high-water conditions. The cause may be electrical, mechanical, float-related or discharge-related.
What This Problem Can Mean
Sump pumps are often the last line of defense against groundwater entering a basement or lower level. If the pump is not operating, the priority is limiting water damage and determining whether the pump, power, controls or discharge system has failed.
Warning Signs
Pump does not start as water rises
Pump runs continuously without lowering water
Float is stuck or obstructed
Pump makes noise but moves little or no water
Discharge pipe is frozen, blocked or disconnected
Water level is rising above the sump basin
Possible Causes
Failed pump motor
Stuck or failed float switch
Power outage, breaker or receptacle problem
Blocked or frozen discharge piping
Pump undersized for current inflow
Check-valve or installation issue
What To Do Now
Keep electrical safety in mind around standing water
Check whether the pump has power only if the area is safe
Move valuables away from rising water
Call for service if water continues rising or the pump will not operate
What Not To Do
Do not enter water near energized equipment
Do not repeatedly reset a breaker that continues to trip
Do not discharge water where it will flow back toward the foundation
Do not rely on a failed pump during continued rainfall
