What is the main purpose of a sump pump in residential plumbing?
Correct Incorrect A sump pump is installed in the lowest point of a basement or crawlspace to pump out water that accumulates in a sump pit, often due to rainfall or groundwater. It prevents basement flooding and water damage, which could result in mold or structural problems. Some models also feature backup power to operate during outages.
