But if the thing does not hold pressure, (Water hater off but water lines Charged with 45-50 PSI) if it holds with the heater off you have a different problem

But that TPR valve (Temp Pressure Relief) is at the top of the tank it is not possible to empty the tank from that port.

He may mean that it emptied his fresh tank. If left on and he didn't notice the pump running I guess it would empty the fresh tank

Water heater spillage from pressure relief valve, emptied water tank. Is the pressure relief valve bad?:h

Probably, but once you change it, check your water pressure and hot water temperature to make sure they don't exceed the limits of your new valve.
