I am nearly finished creating a bathroom upstairs in our home. My issue is concerning the installation of the tub spout. I have tightened the spout (threaded) quite tight by hand and the spout is facing upward! I am worried that if I tighten it too much, I will break the solder seal in the threaded copper supply pipe.
Well if the spout is where it needs to be in relation to the tub wall, I'd just back it off a half turn and point it down. There isn't much pressure in a tub spout as it either flows out the end (or up to the shower head if there is a diverter).
