A tap assembly includes a body with a chamber having an inlet and an outlet, and a seat therebetween. A clapper is disposed for movement relative to the seat between a first position engaged upon the seat for resisting flow of fluid toward the outlet, and a second position of for permitting flow. The tap assembly also includes a reciprocal positioning assembly with a rod mounted for axial movement between a first position for allowing the clapper to engage upon the seat and a second position for precluding the clapper from engaging upon the seat; a cylindrical housing; and an elastically deformable elongated element which forms a split ring positioning unit for the rod. The positioning unit has an inner ring and an outer ring.
