Your question isn't really clear. You have 3 valves? On top of the heater, where the two lines go into it, they should be marked Hot and Cold or H and C. Where is the valve in relationship to these? Most heaters have 1 valve on the cold side. Some may have one one the hot side so that the heater can be removed without draining the entire system. If it is a gas heater, the gas line has a shut off valve, but that should be lower down on the tank. Detail your question if you can. It's hard to see what you see from here.
