Perhaps this is a normal occurrence and I am just not aware as I don't think I have even used a copper stub out before for the tub spout. Anyhow, I have completely redone all of the supply and DWV plumbing in the whole house and working on the bathroom finishing at this point. For the long runs, I used PEX, but chose to use copper for all of the rough-ins for fixtures and the like for rigidity. All has worked well so far.
I used a 1/2" copper stub out for the tub spout. I used a vertical piece, elbow, then horizontal piece to the spout end. The vertical piece is secured to blocking in the wall with a strap that is just above the elbow where it turns out. The vertical pipe itself isn't that long, maybe 3" MAX, if even that. I installed the spout, tightened the set screw and the rear of the spout is flush with the tiled wall. However, it doesn't feel as solid as the original spout did, which was galvanized. This makes some sense to me and I should say it isn't "flimsy" or even "loose" in the general sense of the words; however, there is some movement when pulling the shower diverter up. Perhaps it is not really a problem at all and this is sort of normal with copper stub outs, and I can accept that, but wanted to ask at least.
Also, for sealing around the spout and at the escutcheon plate for the water valve, I have grout color matched silicone - should I use that, or should I use clear? Tiles are 8 x 16 white glossy and grout is Mapei Avalanche white. Thanks!
EDIT: OK, so I think I may have figured out part of the problem that may lead to having to do something else. The Delta instructions fail to mention that the rubber o-ring in the spout is NOT actually a stop, but instead is suppose to go over the copper pipe. I found the thread linked below and while not mentioning a loose spout, it did pique my interest because I measured and fit the same way he did.
So, looks like I may have to go the sweat connection route because I assume where I have it cut is too short. The instructions are pretty terrible.
