A snorkel valve assembly (34) including a sleeve (28) having a rim (30) and defining an opening (32). The assembly (34) includes a diaphragm member (36) having a peripheral sealing surface (38) for selectively sealing off the opening (32) by sealing engagement of the sealing surface (38) with the rim (30). The diaphragm member (36) has a pushed closed position wherein fluid flow within the sleeve (28) draws the sealing surface (38) of the diaphragm member (36) into sealing engagement with the rim (30) and a neutral position when there is no fluid flow within the sleeve (28) space wherein at least a portion of the sealing surface (38) is spaced from the seating rim (30).
