The pipe joint to the spout should not leak.
Spout should fit tightly to pipe and the O-ring should make
a good seal without doing anything else. Get another spout.
You must caulk the spout to the wall to prevent water
splashing during showering from running behind.
The neat way is to apply the caulk to the back of the
spout and then push it on till the caulk squeezes out.
