I see how that would work but I've plumbed in a loop without the H configuration and I'm curious if I have to redo it. I would order the diagram you posted but these sprays are the R50200 I've mounted sideways. With the threaded conections I HAVE to loop it around to a tee then to the diverter. If the pressure is good I'm thinking I should be okay.

Causal Loop Diagram - Tool/Concept/Definition A causal loop diagram (CLD) explains the behavior of a system by showing a collection of connected nodes and the feedback loops created by the connections. One or more of the nodes represent the symptoms of the problem. The rest of the nodes are the causal chains causing the problem.. The simplest possible CLD contains two nodes. Below is an example from video 3 in The Dueling Loops Video Series.
