ABSTRACT:
A vinyl lined tank has a manway opening formed of a vertical portion and a horizontal flange, with a vertical pathway, open at the bottom, inside the vertical portion that communicates with a conduit in the flange or in the vertical portion so that a vacuum can be maintained within the pathway that prevents the collapse of the liner when the tank is empty.
