Moisture in crawl spaces and basements is common, especially if the area is not properly waterproofed or encapsulated. Sump pumps help manage this moisture by pumping excess water out. But what if the sump pump alarm sounds? What does it mean?
This page explains the sump pump alarm and what to do if you encounter this situation.
Sump pump alarms activate when water levels in a basement or crawl space rise to critical levels. This signal indicates that the pump may struggle to remove the water effectively, preventing floods and water damage.

Sump pumps are activated by a float switch that detects the water level in the sump basin. The pump runs as long as it needs to pump the water out and lower the water level. For example, the water table is high throughout Virginia, especially during rainy seasons, so it isn’t a problem if the pump runs frequently.
