    Default pressure balancing loop for 4 sprays

    i am installing 4 22-nozzle kohler body sprays (all controlled off of one volume control). i have searched for how to plumb for 4 sprays. i have found diagrams for 2 and 3, but not 4. the manufacturer siad that i did not need to run 2 separate loops and have 2 separate volume controls for 4 sprays, but i cant seem to find how to plumb it. my thinking was to have an "H" formation with the 3/4" pipe t-ing to 2 other t-s and place each spray and the ends of the "H". not really a loop, but water pressure should still be held constant throughout. any ideas or suggestions?

    That is the way I would do it. I have NEVER installed a "pressure balancing loop", since all they are is a way to waste time and money.

    I suggest using the loop this way each head will evenly spray, Other ways may work and may not depending on volume and pressure. Check out this pdf from grohe page number 9
