The average cost to replace a sump pump is $300 to $750, though it can range anywhere between $110 to $1,000. The cost essentially depends on the price of the unit and the company you hire to do the replacement.

Nobody likes waking up to a basement full of water. If you live in an area with heavy rainfall, a sump pump can be a godsend. But what happens when your trusty ol’ pump stops working? When it’s time for a replacement, it’s important to know what you’re getting into, cost-wise.

How Much Does a Sump Pump Replacement Cost?

A sump pump replacement costs less than a new installation, at about $300 to $750. On average, you’ll pay $500. This is because the replacement process isn’t as time-consuming or labor-intensive as a new install. There’s no digging required; you just have to remove the old pump and install the new one. 

“It’s always a good idea to have the contractor clear the pit with a wet/dry vac and ensure you are starting clean before installing a new pump, as cleanliness is what makes a pump last a long time,” says Joseph Wood, Angi Expert Review Board member and master plumber.

How Do I Know When It’s Time for a Replacement?

If the motor is faulty and/or your pump is over 10 years old, it’s time for a replacement. If you’ve noticed that your pump is running nonstop or cycling on and off, these could also be indicators that your sump pump is failing. A top-rated local plumber can tell you whether or not you need a replacement.

How to Save Money on a Sump Pump Replacement

The best thing you can do to save money on a replacement is to check on and maintain your sump pump throughout the year. This way, your pump will last as long as possible. It’s especially important to ensure your pump is in good working condition during storm seasons, before predicted heavy rainfalls, and before snow melts.  

Here are some routine maintenance tips for taking care of your sump pump:   

  • Check the pump’s position. Vibrations can cause a sump pump to shift position, so you should periodically check to make sure that your pump is sitting upright.

  • Test the pump. Pour water into the pit to check that your pump is running properly. Do this several times a year.

  • Clean the pump. Clear away any debris and check to make sure the inlet screen (located at the bottom of the pump) isn’t clogged. Do this every three to four months.

  • Get a filter. A filter helps keep things out of your pump, prolonging its lifespan. Using a piece of window screen can be a simple solution for keeping items from getting into the pit.

  • Hire a pro. Consider hiring a sump pump professional near you to perform an annual maintenance checkup. A sump pump contractor will check to make sure that the pump empties correctly and that the float is in working order.
