Visual Inspection
During your sump pump inspection, ensure the pump is disconnected from the power outlet and the power cord shows no signs of wear or damage. After putting on proper safety gear, check for any visible corrosion or cracks in the unit. Make sure the sump pit is clean, free of dirt and debris that could block the system, and large enough to accommodate both the pump and high volumes of water during heavy rainfall.
-
Checking the Operation
Activate the float switch by pouring water into the pit to test the pump’s operations. Make sure it moves freely and performs accurately at the right water levels. Check if there are any unusual buzzing or grinding noises during the operation, hinting at mechanical failure. Make sure the pump is functioning efficiently, quickly removing water from the pit.
-
Checking the Discharge Line
Inspect the discharge lines for any blockages, damage or misalignment. There shouldn’t be any loosely connected pipes, rather securely fit to the pump. Check and ensure that the discharge area is not blocked and water flows smoothly away from the foundations of your home.

Electrical and Backup Systems Checkup
Check and ensure the sump pump is connected to a well functioning GFCI (Ground Fault Circuit Interrupter) outlet. Test the outlet and ensure that the circuit breaker is in good condition.
