Why differences in GPM-specs for products which "work together"

I am considering Delta T4768-SS using "optional" cartridge RP73598 and required "rough" R4700-FL for a very-nice Soaking Tub. Seeking products which maximize flow-rate fro 95-gallon (maximum) tub. BIG percentage differences given between these three products at 70-psi: -T4768 Spec-Sheet (with RP73598) approx. 10.2 gpm (per graph) -RP73598 Spec Sheet approx 12.0 gpm (per graph) -T4700-FL NONE SPECIFIED (NO graph) Q-What would be the FINAL flow-rate (GPM) for this EXPENSIVE installation? Q-is there a way to INCREASE flow-rate? Q-Is there a conflict when R4700 specifies "Pressure-Balanced" Cartridge [per "sell-sheet"] vs RP73598 NOT "Pressure Balanced'? Q-Is there a higher-GPM DELTA Floor-Mounted Tub-Filler system than the above system?
Asked by: TigerSpace
TigerSpace, Thank you for your questions! The final maximum flow rate will depend on the pressure in your home and can be determined from the flow rate graph in the Technical Specifications for the model T4768-SSLF (approximately 10.2 GPM at 70 PSI with RP73598). The only way to increase the flow rate is to use RP73598. The RP73598 cartridge does not have a pressure-balance spool, which means there is less restriction within the cartridge. All of our floor-mount tub fillers have approximately the same flow rate. Best regards, Jon

water is not getting hot, how do I adjust

Asked by: Dave
Hi, Dave! Thank you for your question. This RP73598 cartridge does have a rotational limit stop that can be adjusted to get hotter water. Here is a how-to video in our video gallery on how to adjust the rotational limit stop: Best Regards, Rosanna

Does this cartridge work with 14 series tub and shower trims ?

Asked by: Rieaz
Hi Rieaz, Thank you for your question. This cartridge will work any R10000 rough-in valve. However, since it is not pressure-balanced, it is not designed for use in showering applications in the US or Canada. Best regards, Jon
