Abstract: A beverage line (1) and a water line (2) exit from a Python cooling system (3) and enter a manifold (4). The beverage line (1) runs directly through the H-shaped manifold (4) to a tap (5). The water line (2) enters the manifold (4) and water flows through and exits through pipe (6) which surrounds the beverage pipe (1). Adjacent the tap (5), the water flows out of the coaxial pipe (6) and down return pipe (7) which connects into the manifold (4) at connection point (8). The water flows out of the manifold (4) through pipe (9). A bypass pipe (10) is provided in the manifold (4). This allows narrower gauge pipes to be used in the cooling loop without throttling the is flow of water through the Python. A valve (11) is provided in the bypass pipe (10) allowing the flow through the bypass pipe (10) to be reduced or shut off, so that all the flow through inlet pipe (2) is directed through the cooling loop, to remove airlocks.
