Delta Shower Fixtures


I'm building a shower for a client. I have experience with plumbing a basic shower setup with a few peripherals...
The setup is, delta multichoice mv, delta 3-6 diverter, 2x delta body sprays, standard type delta shower head as well as a 12" rainhead, and a handheld wand.
I have a 2 part question.
1st pertaining to the body sprays, since there is only two, should I loop them together or just T off to them with equal sized leads. I heard of pressure issues with 3 or more. But no diagrams when just using 2.
Secondly, my client is not being helpful with choosing what to run simultaneously. My diverter will allow 3 functions of 2 fixtures at the same time. What would be a "common" setup. Like. Rainhead+body spray or shower+wand...etc.
Any help is much appreciated.

It only has 1/2 there now.
The 3/4 mains are under a new floor about 5 feet away.
Can I just convert it to 3/4 where it comes through the wall plate or is that pointless. I know keeping it 1/2 water flow will be terrible.

A follow up question to that. Is it best to stay with 3/4 for the whole install, or is is safe to use 1/2 after the mv or diverter.

Uh, no. The purpose is to go back to 3/4 for volume required by those devices. You need to go back to 3/4. But it's Delta, throw it in the garbage and go with Moen.

Thanks for that. I appreciate the feedback. Do you think it would be fine if I were to just convert it to 3/4 just above the floor plate? The branches to the mains are only about 5 feet long of 1/2" under the floor. The floor is new, and it Is almost inaccessible from below.
As far as swapping for moen. I wish lol. Not my choice. Customer special ordered everything.

No, you need no flow reduction between the 3/4 and valves.

Re: Delta Shower Fixtures


Go 3/4 to the mixing valve, you may need 2-2" drains and lines....

Loop the sprays, easy enough do.

You have to go 3/4" back to the 3/4" main off the water heater and main cold feed. Latest bath remodel had 4 3/4" lines feeding the shower valves.
