There are two main types of sump pumps: pedestal and submersible. A pedestal sump pump has a motor that sits above the pit, while a submersible sump pump has a motor that is submerged in the pit. Submersible pumps are typically more durable and efficient, but they are also more expensive.
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.
Installing a sump pump can be a complex process and it is best to hire a professional to do it properly. The process typically involves digging a pit, connecting a discharge pipe, wiring the pump, and then testing the system to ensure it is working properly.
