Little Giant Pump's Vertical Diaphragm Switch

September 3, 2003
Little Giant Pump Co.’s new Vertical Diaphragm Switch goes anywhere a sump/wastewater pump will go, and won’t hang up in a basin as float switches can. Available as a separate unit for retrofitting, and is also available on many of the company’s sump, effluent and sewage pumps.
