I am installing a Hansgrohe Thermobalance II shower valve to control a shower head and handheld shower. Can someone explain a straight forward way of plumbing the wall union (elbow, as I've also heard it called) for the hand shower? I am confused on how I can justify the angle of the union and keep the nipple length accurate. This is the union I will be using (part number 27454002):
Also, there are two versions of this union; one has a vacuum breaking check valve, the other doesn't. What would determine if I needed the check valve model or not?
Thanks!
