Marc the plumber : Generally with this installation yes you will get flow from both tub and shower nipples without any restrictions such as the tub spout and shower head
Marc the plumber : Once the tub spout, shower head and shower arms are in place it gives enough restriction to force the water to the tub spout which will have a diverter on it. Once the diverter is closed on the spout then water will be forced to the shower head.
Marc the plumber : The one thing that I always concern myself with is the type of piping. If you have used pex to the tub spout you may have a problem as pex fittings are a bit more restrictive than copper so it acts as a natural diverter and will send water to the shower head (unwanted).
Thanks Marc... on the road....additionally, some Kohler literature says you cannot install a stop on the shower head. For on off use only while showering is it ok to use a head with an on off push lever? And are the dielectric fittings good? To protect the copper? I'll try a temp install of the heads this morning and answer back and credit you when I get home.
Marc the plumber : It is not recommended to use this type of stop due the the amount of back pressure exerted onto the diverter however i personally have one. So I won't say no. Also, dielectric unions are for 2 dissimilar metals. Copper and brass are similar. It is rare to use anything other then straight copper.
