A sump pump is commonly used in low lying areas where homes are built below the water table and when basements and crawl spaces accumulate large amounts of water every time it rains.
When installed properly, the sump pump system can protect your home from flooding and from moisture that has accumulated over time. The sump pump is placed in the lowest area under the home and is used to pump water outside of the foundation walls or into the home’s existing drainage system. The sump pump works in conjunction with a sump pit, and often requires french drain systems directing water to the drainage basin.
It is critical for a sump pump to always be working; otherwise the sump pit can overflow and do serious damage to your home’s foundation. A backup power supply system is needed in case the primary power system for the sump pump fails or is out for a long period of time. Battery backup pumps work during power failures by battery power.
