A P/V valve that can be positioned at a working height above grade (i.e., a height reachable by a service technician positioned at grade) while still providing appropriate resistance to fire and explosion by venting to atmosphere at an appropriate height above grade (e.g., 12 feet) is disclosed. In certain exemplifications of the present disclosure, the P/V valve features a diaphragm actuated two-way poppet valve actuatable by a valve piston. In alternative exemplifications of the present disclosure, the P/V valve is positioned intermediate grade and the distal end of a P/V valve riser pipe and is contained in a vault fluidly connected to the P/V valve riser pipe, the P/V valve locally venting in the vault, which is hermetically sealed to the P/V valve riser pipe.

A soda gun housing may include (i) a plurality of enclosure walls defining an internal space; (ii) a manifold support connected to at least one wall of the plurality of enclosure walls and that is configured to secure a soda gun manifold; (iii) a retraction component anchor connected to a part of the plurality of enclosure walls and that is configured to secure a retraction component to the part of the plurality of enclosure walls, wherein the retraction component is connectable to a hose clamp configured to clamp onto a soda gun hose extending from the soda gun manifold secured by the manifold support; and (iv) a hose opening positioned on a wall of the plurality of enclosure walls and that permits the soda gun hose to extend from the internal space to an exterior of the soda gun housing.

A cold plate includes a cold plate body. A tubing system is embedded within the cold plate body. The tubing system includes a prechill circuit, a plain water postchill circuit fluidly connected to the prechill circuit, and a carbonated water postchill circuit fluidly connected to the prechill circuit.
