Budwich, I was referring to the pressure valve of some sort that is built into the city-water twist-on connection. It has a spring, I think, that keeps water in the TT's lines from draining OUT of the city-water connection when city-water hose is not connected. When I press this, it shoots water OUT....so I know city-water is building some pressure in the TT lines when the faucets are closed, but not filling the tank.
Coincidentally, I have also tried the outside pressure releif valve that you refer to, and again water does shoot out of the outer relief faucet....
But the tank feels and sounds empty... I never hear it filling (when i gently lift/rock the tank or tap on it) except for an occasional splash.
Maybe I am crazy, but it feels/sounds empty....??
The only way water can come out of the outside pressure relief valve is if the tank is full. If the tank is full you will not hear water entering it or sloshing around. Either open the drain plug to verify the water inside to satisfy your curiosity or turn on the water heater and wait an hour (warning if the tank is empty you will damage it by heating it empty. Then open a hot faucet and see if the water temp has gone up.
The only other thing I can think of is if somebody installed the check valve on the cold water in but then you would not have anything at your hot faucets.
