What is a sump pump?
A sump pump, also known as a pompe de puisard, is a device typically installed in a basement or crawl space to evacuate water that accumulates around your building's foundations. Its primary functions are:
- Protect your home against excessive humidity and water backflow
- Maintain a healthy water level under the basement floor
- Avoid problems of mould and structural deterioration
Its proper operation is essential to preserving the integrity of your building, especially in regions subject to heavy rainfall or with a high water table, as is sometimes the case in Greater Montreal.
Why install a sump pump?
A installation sump pump is a preventive and protective measure for your home:
- Flood risk reduction In the event of heavy rain or melting snow, the sump pump quickly evacuates accumulated water.
- Preserving health Less humidity in the basement means less mold and bacteria.
- Value added to the property A watertight, well-maintained basement enhances the value of your home.
- Protecting your assets Avoid water damage to floors, walls and furniture.
How does a sump pump work?
The system usually includes a sump pit embedded in the basement floor. When a certain water level is detected :
- The float activates: It triggers the sump pump motor.
- Water is pumped out: The sump pump directs water outside the building through a discharge pipe.
- Secure discharge: Water is evacuated safely away from the foundations to prevent infiltration.
This automatic mechanism guarantees efficient water management, without the need for manual intervention on a daily basis.
Available sump pump types
Here are the main types of sump pumps:
- Submersible pumps : Placed directly in the sump, it is discreet and produces little noise.
- Pedestal pump: The motor is positioned above the water level, generally less expensive but more visible and slightly noisier.
- Battery backup pump : Maintains operation even in the event of a power failure.
- Combination pump : Combines a main pump and an emergency pump in the same device.
The choice depends on your budget, available space and desired level of protection.
