A sump pump is a small pump installed in the lowest part of a basement or crawlspace. Its job is to help keep the area under the building dry and to prevent it from flooding. Usually, sump pumps are installed in specially constructed sump pits. Water flows into the sump pit through drains or by natural water migration through the soil. The sump pump’s job is to pump the water out of the pit and away from the building so the basement or crawlspace stays dry.
But even more homeowners are likely to have to deal with a flooded basement at some point. It doesn’t take much water to cause thousands of dollars of damage. A moist basement can also lead to mold and mildew growth, bringing with it all its related health and breathing hazards.
