If the pilot flame is too high a thermocouples life could be shortened. Check the specs of the unit supplied by the gas valve for the working pilot pressure. Or put the gas valve in pilot and depress the pilot push button. Keep the button down with a small screwdriver, remove the thermocouple from the gas valve and check the millivolts on the thermocouple. Place one lead on the copper tubing and the other lead on the end of the thermocouple, the silver looking part that touches the inside of the gas valve. With the pilot flame on you should read anywhere from 22-29 millivolts. Anything below that is a sign that your thermocouple is failing. It might work for awhile, but it will probably go out in the middle of a long cold winter night. ;)

No, that is part of the function of the pilot light. To light the burner and to keep the gas valve open. The thermocouple sits in the flame of the pilot and produces a small electrical current that keep the gas valve open. When the tank cools down, the thermostat opens the valve to the burner so that it can light. When the pilot goes out, it is usually the thermocouple that is bad.
