Abstract
A fluid level management system for controlling a fluid level contained within a reservoir housing is described. The fluid level management system utilizes two separate predetermined fluid levels, a first and a second spaced below the first, to create a fluid level differential though which a control apparatus actuates a single activation switch. Use of the fluid level management system in conjunction with a pump for removing the fluid contained within the housing is further described. The pump is responsive to the control apparatus actuating and deactuating the switch depending on the fluid being at the first or second predetermined fluid level, respectively.
