How Does a Sump Pump Work?

Posted June 30, 2016

Sump pumps are an important addition to a basement that sees water or flooding often. Along with a clean crawl space near Tacoma, WA, a sump pump may be the only thing between you and an expensive water and mold remediation experience. Here is a look into how exactly sump pumps work to keep your basement dry.

  1. If the sump pit—the hole in which the pump stands in—begins to fill with water, the pump turns on. It will suck and move the water through pipes that drain the water away from the house and foundation.
  2. The water is detected by a float activator, also called a pressure sensor. As the float is lifted with the rising water, it will soon trigger the sump pump to turn on and flush the water.
  3. Once the pump has removed the basement water, the float will lower, and the pump will turn off.
