    Howdy, I'm planning a bathroom makeover and I am considering purchasing one of those fancy shower system with body jets and shower head. I'm curious how these systems actually perform with the 2.5 gallon flow restriction. Do the body jets reduce pressure from the shower head?

    Along the same line, if you purchase a shower with multiple heads is the combined pressure out of all heads 2.5 gallons or is it 2.5 gallons per head?

    Thanks for the help

    The volume, not pressure, is 2.5 gpm per head until you reach the maximum volume that the valve can deliver. At that point the gpm will drop in all the heads that are being used.

    Thank you for the reply. Since my original post I found the following information at faucets.com

    http://www.faucet.com/decor/static.pl?S=basics/help_custom_shower_systems

    I take this to mean that on a double headed shower each head can provide 2.5 gpm so long as the valve can permit it.

    The article also mentions using a 3/4" valve versus a 1/2" valve. Are these valves usually included with the shower system or must they be purchased seperately? Are these valves dependent on the size water pipes?

    Thank you so much for your assistance.
