I'll be interested in your findings.

The scenario that seems to best fit the observations is that, prior to my ownership the valve failed and rather than repair or replace it, someone just removed the steel disc and plugged it with gasket cement or silicone or something else that over time degraded and eventually failed, opening the line.
