The Case of the Dual Mystery Valves....
OK, so I'm in the process of messing with the toilet in my 78 Tradewind. I'm looking under the vanity/sink, and down below are two factory-looking water valves. They're below the level of the sink cabinet floor, and to the right. They're not the toilet shut-off valve, but they're the same kind of valve. Kinda like if you reached in with your right hand, you could turn them.
You could turn them, that is, if they weren't frozen like these are.
Now, this is nice copper plumbing, they're not leaking, and these valves look sweated in place, so it will be an honest day in Washington DC before I go messing with them just for the heck of it.
But I'm curious - what are they??
