how many gallons of water per minute is required? What is the PSI required for flow?A. The Kohler K-8003 has a flow rate of 2.5gpm at 80 psi.
I want to install the square shower head two square fixed body sprays and the hotel kit hand held what kind of diverter and on off do I need and what else do I needA. You will need a 3 way diverter valve or transfer valve to accomodate all the functions you want to have in this setup. You would probably want to go with the K-728 valve. Hope this helps!
