Why can t you use pex for tub spout drop.

A lot of manufacturers are very specific about this and i ve seen it hundreds of times. Copper is the only professional installation material. With a built in diverter you could use a pex drop eared ninety degree female adapter and a nipple but that is more trouble than it is worth. The interior diameter of pex is actually a fraction smaller than copper this forces water to come out of the shower at the same time as the tub spout.

Also a lot of tub spouts have installation methods that only work with copper stub outs. In areas that are concealed like under a kitchen sink or vanity cabinet you can eliminate a joint by running pex supply directly to the shutoff valve. How did this project turn out. Long story short it is unacceptable.
