Sump pumps are essential parts of many homes in Florida because of the stormy season that can create terrible flooding. In many parts of the country, sump pumps are installed down in basements. Homes here in Florida rarely have basements, so the sump pumps are part of the crawlspace where they remove water from the lowest part of the building structure and pump it out into the wastewater system. A professionally installed sump pump protects a home from serious water damage and keeps away excess moisture that can lead to mold and mildew growth.
