Buying a home with a sump pump: Here are 10 things you need to know before purchasing!

Updated: Oct 6, 2023

Sump pumps can be lifesavers for homeowners, especially those who live in areas that are prone to flooding. If you're buying a home with a sump pump, there are a few things you should keep in mind to ensure that it's in good working order and will protect your home from water damage.


1. Check the age of the sump pump. Sump pumps typically have a lifespan of 10-15 years. If the sump pump in the home you're buying is older than that, it may be time for a replacement.

2. Ask the seller about the sump pump's maintenance history. A well-maintained sump pump is more likely to last longer and work properly when it's needed. Find out how often the seller had the sump pump serviced and what kind of maintenance was performed.

3. Inspect the sump pump basin for signs of water damage or corrosion. If the basin is damaged, it may not be able to hold enough water to activate the sump pump.

4. Test the sump pump to make sure it's working properly. Pour a bucket of water into the sump pump basin and watch to see if the pump turns on and pumps the water out.

5. Find out if the sump pump has a backup power supply. A backup power supply will keep the sump pump running even if the power goes out during a storm.

6. Ask the seller about any history of flooding in the basement. If the basement has flooded in the past, it's important to find out why and what steps have been taken to prevent it from happening again.


7. Consider installing a sump pump alarm. A sump pump alarm will alert you if the sump pump fails or if the water level in the basin gets too high.

8. If you're buying a home in a high-water-table area, you may want to consider installing a second sump pump. This will help to ensure that your basement stays dry even if one sump pump fails.

9. Make sure to have the sump pump serviced regularly. A qualified plumber can inspect the sump pump, clean the basin, and make any necessary repairs.

10. Keep the sump pump basin clear of debris. Debris can clog the sump pump and prevent it from working properly.


Buying a home with a sump pump can be a smart investment, but it's important to do your research and make sure that the sump pump is in good working order. By following these tips, you can help to ensure that your home is protected from water damage.
