shower has been converted to ada from a basic standard tub.

The ada now has a sitting area with a handheld shower head on one end and a fixed shower head on the other head.

Question is: what is the proper way to show the plumbing connections for this setup? Not sure if I have shown it correctly.
(There is a diverter valve with access panel right in the center)

See pics of drawing below for details.
