The sump box contains a super reliable, mercury-free float switch and a pump. The pump automatically starts and removes accumulated water as the sump box fills, a check valve in the inlet manifold prevents the pump from cycling and reduces standing water odor. A clear, gasketed plastic lid allows for easy filter inspection and service. Three inlet sizes allow hook-up of multiple drains, using different hose sizes. Test knob allows for easy, immediate operational check. Air vent prevents air locks
