As the name suggests, a sump pump is the pump used to remove water from sumps usually found at the basement of the house. It serves to keep the basement and foundations of the house dry to prevent seepage which not only damages the building, but even the repair work may turn out to be very costly. The issue is very common in houses where the water table lies above the foundation of the house or in areas which have heavy rainfall. It also becomes very vital when the snow begins to melt and there is a chance of flooding. Its main job is to pull the water out of the pit at the basement of your house and drain it to the garden or any other area away from the house.
