Sump pumps should be checked and maintained at least once a year. This includes checking the pit, the pump, and the discharge pipe for any debris or blockages, and making sure that the pump is working properly.
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.
If your basement or crawl space frequently floods or has a high water table, you may need a sump pump to prevent water damage. Additionally, if you have a history of water in your basement, or if you live in an area that is prone to heavy rain or flooding, a sump pump can be a good investment.
