Sump
pumps are a component of a waterproofing system that enables the collection and
discharge of water that may accumulate in a low part of a home or building
(typically a basement) and enable that water to be safely moved outside of the building
to prevent flooding. When the water table rises due to heavy rains saturating
the soil, water pressure builds up and may force water to enter a building
through foundation cracks. Without a sump pump to clear the water, the
level may rise and flood the low points of the building, causing damage to
equipment and items located there.
Sump
pumps sit in a well or collection reservoir usually cut into the basement
floor. A level switch turns the pump on when the water level in the reservoir
begins to build, and the water is then discharged through a system of pipes
outside of the building and away from the foundation. This system keeps
operating to maintain control over the water and prevent flooding. Most systems
include battery back-up capability in the event of a failure of the primary
power system.
