Hello! I am in the process of trying to (learn to) fix some odds and ends around the house on my own. I had a leaking shower head that I was able to fix on my own, but this issue I am not so sure about. Whenever I pull the the stopper on the bathtub spout to activate the shower, water starts coming out behind the spout (The shower still works, though). The stopper itself seems to work fine, though, as no water comes out of the spout at all in the front when activated. It's only where the back of the spout meets the wall. As you can see in the pics, the caulk is dried and cracking off. I see that there is no set screw, so I assume that this spout unscrews. Is it a matter of just taking the spout off, cleaning off the old caulk and resealing where it meets the wall? Or is there more to it? For some reason, I feel like if I seal it off that pressure will build up in the spout itself and it will leak through the wall. Any help would be greatly appreciated! *Edit* I also wanted to add that the water definitely comes from the front of the spout-side and then trickles out the back. The water isn't coming from the wall-side.
