Signs that a sump pump may not be working properly include water pooling in the pit, strange noises coming from the pump, or a lack of water being discharged from the discharge pipe. If you notice any of these signs, you should have your sump pump checked by a professional.
A sump pump is a device that is installed in the lowest part of a basement or crawl space to pump out excess water that may accumulate due to groundwater or other sources. It typically consists of a pit or basin, a pump, and a discharge pipe. Water is collected in the pit, and the pump then pushes the water out and away from the building.
