The valve assembly disposed within a water supply line upstream of a water meter. The valve assembly is structured to reduce or significantly eliminate the passage of air, separate from water flow, through the meter and includes a housing having an interior channel and a valve body movably disposed within the channel. The valve body includes a sealing structure which is biased, under a predetermined force, into sealing relation with an inlet of the interior channel. The predetermined force is sufficient to prevent displacement of the sealing structure out of the sealing relation with the inlet, but insufficient to prevent displacement of the sealing structure when force from a normal water flow is exerted thereon from within the water supply line. As a result any air flow within the water supply line will be compressed or otherwise disbursed and prevented from passing, independently, through the meter, thereby preventing unnecessary charges being made to the metered facility.
