Thank you for your question. To add the Delta Body Sprays 50150-SS you would need to also install the R11000 3/6-Setting Diverter Rough-In Valve. The flow rate will be primarily determined by the main valve and trim that you use (R10000 + 13/14, 17, or 17T trim). The approximate maximum flow rate from the diverter valve at 60 PSI is:
14 series - 5.8 GPM 17 series - 5.9 GPM 17T series - 7.3 GPM
With R10000-UNBXHF (High-Flow):
14 series - 6.3 GPM 17 series - 6.6 GPM 17T series - 8.6 GPM
At 80 PSI the flow rate is increased by approximately 1 GPM.
These are the maximum total flow rates from the diverter valve in a shared position.
The maximum flow from an individual diverter port is limited to 5 to 6 gallons per minute, depending on pressure and the trim series chosen.
