What is a sump pump?

A sump pump is a mechanical pump installed in a basin (called a sump pit) at the lowest point of a basement or crawlspace. When water collects in the pit, a float switch triggers the pump to activate automatically, pushing the water up through a discharge line and away from the home's foundation.

In Aiken's climate and soil composition, sump pumps address a real problem. The area's clay-heavy soil drains poorly and can trap water around foundations, especially after heavy rain or during wet seasons. Without a sump pump, water pressure against basement walls increases, leading to potential leaks, foundation damage, and moisture problems in crawlspaces.

Most residential sump pumps operate on household electricity and use either a submersible design (submerged in the pit) or a pedestal design (mounted above the pit). They run continuously as needed, which is why many homeowners also install a backup battery-powered unit to ensure the pump keeps working during power outages. The discharge line typically runs to daylight or a storm drain system away from the foundation perimeter.

If your Aiken home shows signs of basement water intrusion or damp crawlspaces, a residential plumber can evaluate whether a sump pump installation or upgrade is necessary for your property.
