Abstract
An extra-vehicular activity water system (EVAWS) is provided and includes a body defining an interior, a quick disconnect assembly fluidly communicative with the interior and with at least one of an external reservoir and a plumbing system of an extra-vehicular mobility unit (EMU), a piston and a pressure feedback feature. The piston includes a piston head configured to engage with the body to adjust a volume of the interior and a handle by which the piston head is movable to draw fluid through the quick disconnect assembly and into the interior from the external reservoir and to force fluid through the quick disconnect assembly and into the plumbing system from the interior. The pressure feedback feature maintains fluid forced into the plumbing system at pressures above and below minimum and maximum pressures, respectively.
