When a sump pump stops removing water, check the pit for debris, the intake for clogs, the check valve on the pipe, and the outdoor end of the discharge line. Work from a dry spot, and leave any repairs that involve the pump itself or its wiring to a plumber.
Step 1: Look Into the Pit
From a safe spot, look into the pit. Is the water level dropping when the pump runs? Is the pit full of mud, gravel, or other debris? Heavy debris can block the pump and wear it out faster.
Step 2: Listen to the Pump
A pump that runs smoothly but moves no water may have a clogged intake screen or a jammed impeller. A loud hum without movement often means the impeller is stuck or the motor is failing. If you smell something burning, turn off power at the breaker if it is safe to reach.
Step 3: Follow the Pipe
The discharge pipe should carry water up and out of the house. Look for a check valve on the pipe near the pit. If water rushes back into the pit after the pump stops, the valve may have failed. Also look for cracks or loose joints that leak water back into the basement.
Step 4: Check Outside
Go outside and find where the pipe ends. Make sure the outlet is not buried under snow, leaves, mulch, or soil. In winter, the line can freeze, which blocks water from leaving. Water that drains right next to the foundation can also flow back toward the pit.
If none of these checks show the problem, or if the fix means taking the pump apart, it is time to call for help. A plumber can check each part of the system and fix what is wrong.
