Tub spout/shower diverter question

On a single-handle, pressure-compensating control valve (with no separate diverter) I'd like to know if the water flow normally "favors" the spout port only because of gravity, or is there a check valve in there?

Usually it's just gravity. The pipe up to the shower head is always open. It's only when you raise the diverter on the tub spout, blocking the water's path, that the water backs up and flows out the shower. Some shower heads do have a sort of check valve system I think to prevent dripping so when you turn the water off the shower stops immediately and doesn't continue to drip for several minutes.

That's what I thought. I was considering adding a rain head and using the capped Tub port but I don't think I'd have any real control over flow from each head unless I piped off a single port and went through a divertor valve.

You will need a diverter valve or two individual shut offs in addition to the on/off valve so that you can control which heads receive water. What brand of diverter and trim are you using?

I haven't bought a diverter yet--and probably won't. Not worth it to me personally to add the rain head and doing so might encourage others to take longer showers than necessary

In case you meant the control valve it's a Pfister Ashfield with a 0X8-310A tub/shower valve.
