Pool Systems utilize balancing valves on the supply line enabling each bank to have proportional feed which limits the water
to favor the path of least resistance. Notice A) is an example of a Reverse Return Multi-Bank system where the balancing valves are needed and B)
is a Single Bank Reverse Return which doesn’t need balancing valves. Similarly, C) is an example of a Same End Return Multi-Bank system where the
balancing valves are needed and D) is a Single Bank Same End Return which doesn’t need balancing valves.
