We do have a salt pool and I believe my salt is too high. Autopilot is reading 3700, ps234s reads 3200 so I am taking a sample in for testing.
Even using salt though, it is only a month old and the rust is leaving very dark, almost black stains radiating out from under the escutcheon. I would have hoped it would be a long while before anything like this began happening. The gas line is rusting at almost every connection and isn't exposed to salt.
