In one embodiment, the fluid valve is made of collapsible tubing, flattened at its midsection so as to be normally closed, and connecting a fluid inlet and fluid outlet of a fluid removal housing. The fluid removal housing is further provided with a control port which may be opened or closed manually, and a connection to a vacuum source through the vacuum valve.
