ABSTRACT:
A portable system of inter-connected smaller and larger canisters for near simultaneous vacuum and liquid transfer free from any external power. Captured vacuum in the canisters is employed for waste liquid extraction and a subsequent pressure transfer may take place without any liquid being exposed to the atmosphere. A mechanical manifold is adapted to receive the canisters, and one or more canisters may be physically connected to the manifold and are left in place as a user drives to another site location. An intermediate canister in the system is fitted with either manual or a self tending valve for the vacuum and pressure modes of the system.
