What could cause my sump pump to cycle on and off rapidly?
It can be frustrating when your sump pump won't stop cycling on and off. Here are some possible causes and solutions:
1. Clogged discharge line: The discharge line is the pipe that carries water away from the sump pump. If it becomes clogged, water will back up into the sump basin and cause the pump to cycle on again. Check the discharge line for blockages and clean it out if necessary.
2. Faulty check valve: The check valve is a one-way valve that prevents water from flowing back into the sump basin. If the check valve fails, water can leak back into the basin and cause the pump to cycle on again. Replace the check valve if it is faulty.
3. Water level switch malfunction: The water level switch is a device that turns the sump pump on when the water level in the basin reaches a certain point. If the water level switch malfunctions, it can cause the pump to cycle on and off too frequently. Replace the water level switch if it is malfunctioning.
4. Oversized sump pump: If the sump pump is too large for the size of the sump basin, it can cycle on and off too frequently. This is because the pump will pump water out of the basin faster than it can fill up. Replace the sump pump with a smaller one if it is oversized.
5. Leaking sump basin: If the sump basin is leaking, water can seep into the basin and cause the pump to cycle on again. Seal any leaks in the sump basin using a waterproof sealant.
