Why does your thermocouple keep going out?

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. ;)

How do you replace a thermocouple on a hot water heater?

The thermocouple is the small tube that runs between the pilot light and the control valve. The valve end unscrews and the pilot light end in held in place with a spring clip that the tip pushes through. Unscrew the valve end and work the pilot end out by twisting it and pulling it out of the clip. Install a new one making sure the end is in the pilot flame and light the heater. No gas will come out when you take it loose from the control valve.
