I have a faucet similar to this one:
Unfortunately, the pipes were not secured very well behind the enclosure, which I assume is a common problem. Specifically, the valve is not mounted to a cross stud, in fact, there is no cross stud like the one shown below:
Because of this, the pipes are free too move a bit. I have two questions:
I am not sure how much to turn the housing screws that pull the large circular cover as with every turn the valve and pipes pull closer to the enclosure. I am thinking that I tighten them up just past contact, plus a few rotations, and use some thread locking fluid. They have been backing out a bit as the year goes on. Thoughts?
There is a foam/rubber seal behind the cover that is close the outside edge. This prevent water from running down the wall and getting behind the enclosure. Do I need to worry about water getting behind the metal sleeve, shown in the first photo? There seals look like this:
But I am wondering if I need an o-ring like this:
I may answered my own question but it would be good to hear others' thoughts or confirmation, plus it may help others in the future seeking advice.
