    Having trouble getting an answer to this, so hope someone out there can help. I am installing 4 body sprays, two on each of two opposing walls, using one 1/2" volume control valve. The valve can supply about 12g/m at 75psi and the sprays each use about 2.5g/m at 80psi (if my math is right, I should be OK there). Now, I have heard from many sources that a balancing loop is highly recommended to even out the pressure on each spray. I have no problem doing that, except in this case, since I have two and two, can anyone tell me if I should run two seperate pipes from one wall to the other making one "giant" loop, or is just running one pipe and looping at each pair sufficient?? Also, would the 1/2" pipe be adequate to assure even balance between all sprays, or could I / should I go with 3/4" for the distance between the pairs??

    Thanks for any feedback on this one.

    I believe you need one big loop to balance both pairs of sprays. Check with the manufacturer. They usually offer install diagrams.
