   Greetings DJ,

   This post, in response to your question, will bump the thread through the 'recent discussion' listing again which will increase it's viewing.

   Perhaps it will catch someone's attention that can help you with advice.

   Cheers

   Don't know much about the DTV shower but in my experience, one item that often needs consideration 'PRIOR TO' install of the newer, multi head, shower systems is to be absolutely sure your HOT supply is at least 1/2" with good flow/pressure and COLD supply is 3/4", again with good flow, at a very minimum. All these "showroom" showers look great but practicality must be considered along with water supply to feed the whole system. If possible, put in 3/4" all the way around, not just the last 4 or 5 inches ahead of the shower.

   We are ok in that department.  This is new construction, and I have planned accordingly.  We have 1 1/4" supply from the meter to the house, 1" cold main throughout the house and to the 80 Gallon water Heater, and 3/4" Hot to the Master Shower.  The other day, my plumber finished the rough, and turned on the water to test the system.  MAN OH MAN, it is like a FIRE HOSE!!!  I was shocked, because our old house (previously on this same property) had NO pressure or volume at all.  Even the 1/2" hose bib all the way at the end of the line was gushing water out like a FIRE HOSE!!!  What a difference new plumbing has made.

   I can't count the number of people who've posted here complaining about insufficient water flow in their "new shower/bath remodel." It all comes down to planning. It's easy to install the proper size plumbing, or larger, ahead of time but try putting it in after all the tile is done and the job is finished. Not so easy, to say the least, at that point. Be glad you, or your contractor, planned ahead on this plumbing installation.

   At "up to 21 gallons per minute" you had better have a major source of hot water.  80 gallons, even when mixed, isn't much for that sort of volume unless you have serious recovery capacity.

   One of these would help that problem if you have room for it 'down stream'http://gfxtechnology.com/contents.html#selection

   It flows up to 21 GPM with all 6 outlets turned on.  We'll never do that, no reason to.  We are installing a Propane Gas water heater with a fast recovery rate.  I don't expect it to be an issue.
