We owned T1848 (not sure the rough in model) for eleven years and love Delta's products. Recently doing remodeling and want to update to R10000-UNBXHF with T17T038 for shower only. Will that improves the shower and stream flow? Any suggestions? Thanks.
Thank you for your question! The T17T series, along with the High Flow (HF) R10000 valve, will increase the maximum flow through the valve by about 3.6 gallons per minute at 60 PSI. This will increase the flow rate from the tub spout, and may allow you to run additional components with a diverter valve.
However, it will not increase the flow rate from the shower head itself, which is designed to flow at no more than 2.5 gallons per minute.
