When Should I Replace My Sump Pump?


Sump pumps, the submersible pumps that keep water from flooding your basement and ruining your foundation, need to be replaced every several years—usually about seven to 10 years. The last thing you want is for your sump pump to go out during the storm of the century, so make sure you keep up on your sump pump maintenance in Chanhassen, MN.


Not sure when the last time you or a previous owner replaced the pump? Here are the signs that indicate it’s time to get a new one:

  • The pump keeps running: If you’ve noticed that the pump is running even when there isn’t any water present, it risks getting overheated. Check to make sure the float switch hasn’t been flipped to the wrong position—and if not, make plans to replace your pump soon.

  • The pump is clogged: When your pump gets clogged by dirt, grit and debris over time, it can clog the pump and jam the blades. The best way to avoid this problem is to protect the pump from debris, usually by installing a fine grate over the well.

  • The pump makes loud or unusual noises: It’s never a good sign when our mechanical devices make loud, strange noises. This can indicate that your motor is reaching the end of its life, something is jammed in the pump or that the pump was improperly installed. Your plumbing technician can give you insight as to what the problem might be and whether you need to repair your sump pump.

  • The pump is cycling randomly: If you’ve noticed random on-off cycling, that means that either your float valve is too low, the wiring has come loose or the pump doesn’t have enough horsepower to deal with the current water level.

  • The pump hasn’t been replaced in the last 10 years: The average maximum lifespan of a sump pump is 10 years, so if yours hasn’t been replaced in the last decade—and especially if you notice any of the above signs—it’s time to get it replaced. At the very least, consider a backup pump until you can replace this one—you don’t want to be caught by surprise when the next heavy rainfall occurs.

If your sump pump is reaching the end of its useful life, consider replacing it with a self-lubricating cast iron model. They’re slightly more expensive than other types, but will provide better performance. If possible, avoid plastic pumps.

Finally, while you don’t need a backup pump, it’s a smart investment that will prevent expensive repair bills in case of emergency.
