A water pressure sump pump uses the pressure of your municipal water supply to create suction, which then empties your sump pit and discharges the water outside your home. This process relies on physics principles.
Here's a breakdown of how it works:
-
Water Inlet: The pump connects to your main water line.
-
Venturi Effect: The incoming water is forced through a narrow passage called a venturi. As the water's velocity increases in this narrow section, the pressure decreases (Bernoulli's principle).
-
Suction Creation: This decrease in pressure creates a suction effect within the pump.
-
Sump Pit Emptying: The suction draws water from the sump pit into the pump.
-
Discharge: The combined water from the main water line and the sump pit is then discharged outside your home through a discharge pipe.
In essence, it leverages the momentum and pressure of incoming water to pull water out of your sump pit. The downside is that it uses municipal water to operate, which can be costly and means it won't work if your municipal water supply fails.
