The answer to 'how long does sump pump last' is that a typical sump pump has a lifespan of 7 to 10 years with proper maintenance. Sump pumps are essential for preventing basement flooding, but they are mechanical devices that will eventually wear out over time. Factors that can affect the longevity of a sump pump include the quality of the unit, how often it is used, and the condition of the electrical system and plumbing it is connected to.
To maximize the lifespan of a sump pump, it's important to have it serviced annually by a professional plumber. This includes checking for any wear and tear, cleaning the impeller, and testing the pump to ensure it is functioning properly. Homeowners should also be aware of the warning signs that a sump pump is nearing the end of its life, such as frequent cycling, reduced water flow, or unusual noises. When a sump pump needs to be replaced, it's best to consult a licensed plumber to ensure the new unit is properly sized and installed for the specific needs of the home.
