What is a Sump Pump?
A sump pump is a mechanical device installed in the lowest part of a basement or crawl space to remove accumulated water and prevent flooding.
Why Do Sump Pumps Matter in Real Estate?
In Canadian real estate, sump pumps are especially common in flood-prone areas or homes with high water tables.
Sump pump systems typically include:
- A sump pit or basin where water collects
- An electric pump that activates when water reaches a set level
- Discharge piping that redirects water away from the foundation
A working sump pump can reduce moisture, mold growth, and structural damage. Many home insurance providers recommend or require one in at-risk properties.
Understanding sump pumps helps homeowners and buyers manage drainage risks and protect basements from water damage.
Example of a Sump Pump in Action
After a spring thaw, the sump pump in the home’s basement activates several times to divert groundwater and prevent flooding.
Key Takeaways
- Prevents basement flooding.
- Activates automatically in high water.
- Essential in flood-prone areas.
- Requires regular maintenance and backup power.

Average and median describe different aspects of the same month’s transactions. Both are affected by the mix of homes sold.
Category averages compare different homes and locations; the gaps are not estimates of the cost to upgrade an otherwise identical property.
The five categories shown account for 5,000 of the board’s 5,057 sales. The remaining 57 transactions were in other housing categories.
Monthly observations are not seasonally adjusted. Active listings count properties available at month-end; they are not construction inventory.
Average and median prices share one dollar axis. These unadjusted transaction measures do not control for changes in the homes sold.
