Abstract
A system for removing a volume of liquid including a pressure-sealed-pump-vessel, at least one liquid-aperture, a liquid-level-control-valve, a liquid-discharge, a sump-pump, a pressure-sealed-suction-vessel, and one or more vessel-connections. The one or more vessel-connections configured to fluidly couple the pressure-sealed-pump-vessel and the pressure-sealed-suction-vessel, in the preferred embodiment. The sump-pump is located within the pressure-sealed-pump-vessel and includes a pump-inlet and a pump-outlet. The pump-inlet fluidly coupled to the liquid-aperture, and the pump-outlet is fluidly coupled to the liquid-discharge. The sump-pump configured to pump the volume of liquid from the pressure-sealed-pump-vessel and from the system via the liquid-discharge to remove the volume of water from a roof surface or other similar horizontal or substantially horizontal surface.
