The answer to 'how to fix sump pump' is to diagnose the issue, clean and maintain the sump pump, and replace it if necessary. Sump pumps are an essential part of a home's drainage system, helping to prevent water damage by removing excess groundwater from the basement or crawl space. Regular maintenance is key to keeping your sump pump working properly.

Consider replacing the sump pump if it is more than 5-7 years old or if it is not effectively removing water from the pit. For complex issues or if you are not comfortable working with electrical components, it's best to call a professional plumber.
