I have a badly corroded, leaky tub spout that I want to replace. I have zero plumbing experience but it seems this should be a simple task. The existing spout has a hole at the base which would indicate a set screw, however when I look up there I don't see any screws. It looks like the previous home owner squirted a bunch of clear caulking up there and I was able to pull some of it out with tweezers. I still don't see any screws, just the pipe I believe. I'm not sure how to proceed. Any advice would be appreciated. I tried to take a picture but it isn't the most clear.
