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. In addition, if I left the spout in the downward position (the correct position), it is loose enough to move sideways, just by brushing against it.
