Hi. I've seen two diagrams on how to pipe a pressure balancing loop for three body sprays. One has the outlets all on one side of the loop with the inlet on the other side and the other has the outlets in the middle with the loop shaped like a figure 8. Is there a difference with these two designs? Also does it matter where the inlet comes into the loop? Does it have to come in pretty close to center of the loop or can it come into it from anywhere in the loop say at the top next to the first outlet. Thanks in advance.
