There is a calcium build up on the walls of the fountain, which the pool guy said was from the hard water. He is charging to clean that up on a regular basis.
I'm curious about the revision B issue, and that my local guy didn't have (or give) that info when we spoke. Thanks Jim for the heads up. As it is, I've encased the fixtures in epoxy at this point, so there is no exposed metal surface in water anymore.
