Direct return parallel piping occurs when the first branch connected on the supply is also the first branch
connected on the return. This configuration will generally require balancing valves to ensure each parallel
branch receives the design flow.
Figure 1-23 Direct return piping. With individual circulators balancing valves are not required.
