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.
