- This is usually caused by a bad thermocouple. The thermocouple looks like a thick, solid copper wire screwed into the gas valve on the water heater. The pilot flame heats the tip of the thermocouple, causing it to generate a minute electrical current at low voltage, which provides power to an electric valve that controls the flow of gas to the main burner. If you attempt to relight the pilot burner and it refuses to stay lit when you release the button on the gas valve a minute, or so, after the flame has been lit, the thermocouple is the most likely cause. Replacement thermocouples are readily available from most hardware stores and can be replaced by the homeowner, using simple tools, by following the instructions on the package.
- Another cause of the problem could be a lack of air to the combustion chamber. Newer water heaters require more volume of air due to the addition of a heat sensitive diode to the thermocouple. Not enough air flowing through the combustion chamber to carry the heat up through the flue causes heat build up, which kills the thermocouple. On my water heater, I could light the pilot and the water heater would burn for 20 minutes or so and shut off. The fix included routing the flue straight through the roof and opening floor to allow more air into the water heater compartment.
- Another possible culprit may be water-heater vent height above the roof. In some situations this may periodically result in a downdraft that could cause the pilot light to go out. If this is the case adding to the vent height may help. Note: building code states that the B vent required height is based on the roof pitch but it must be 2 feet higher than any portion of the building within 8 feet of the vent.
- Make sure the vent cap isn't missing or rusted through on the roof, it will cause drafts and wind to blow out the pilot.

Answer No because water heaters have a safety valves and when the pilot light goes out the safety valve shuts off the gas
The pilot could be dirty and may be too weak to heat the thermocouple properly. Most of the time it comes down to replacing the thermocouple. ANS 2 The thermocouple costs… less than $19 and can be changed in about 30 minutes. Best to first Shut off gas, and remove your one, then take to the store for comparison. There are 5-6 different types but all very similar. Honeywell Universal is good for many heaters. This is essentially a thin copper tube 18 -30 inches long, with a metal bulb at one end and a hollow nut at the regulator end. Many good instructions on internet about how to do it
Depress pilot valve, hold in while lighting, hold in for 2 minutes while lit. Continue to hold pilot valve in while rotating the gas control to the "on" position. If the pilot… flame doesn't stay lit, it may be due to a bad thermocouple, a device that looks like a thick, solid copper wire whose tip is in the pilot flame and whose other end is screwed into the gas valve. You would need to get a replacement thermocouple from a hardware store or have a handyman install a replacement thermocouple for you. Thermocouples typically last 6-8 years if the pilot flame burns continuously.
Spillage excessive condensate bad thermocouple draft
No If the hole is smaller then the diameter of the supply line
By reading the directions provided with the heater The older types of water heaters have a gas controller that has on top there is a button called pilot and you must turn th…e adjusting knob to pilot then hold the button down , light the pilot tube located just below the thermo couple HOLD it down for TWO minutes (enough time to heat the thermo couple) then release and make sure the pilot stays lit.. Then turn the dial to ON and adjust the temperature On the newer models there is an sparker and you should read the directions supplied with each type of heater . You should also find out why the pilot light went out as down drafts can be quite dangerous.
Hot air balloons have a gas heater attached to them the pilot can turn the heater on the balloon and the balloon will go high why?
Hot air balloons have a gas heater that is generally powered by propane. When the pilot turns the heater on, the balloon will fly high due to the hydrocarbon chamber that …allows the pilot control of ascent and descent of the hot air balloon.
You could have a dangerous vent back flow problem. Please call your utility company about an inspection (mine doesn't charge for this). How old is the water heater?…

"Pilot" is only when initially igniting your water heater. Some manufacturers state to leave it on "Pilot" for so many minutes before turning to on but this is only temporary.… It should be then turned to "On" and then if you have a low, medium or high setting or degrees adjustment, adjust the temperature setting. Remember that most local plumbing codes and water heater manufacturers recommend a temperature of no more than 120 degrees F.
The thermocouple is going bad. The thermocouple is the small tube that sits in the flame from the pilot light and goes back to the gas valve. They are easy to replace and cost… $6 to $8. For health and safety the failing part should be replaced without delay by a competent gas engineer.
Most likely it is the thermocouple going bad. The thermocouple is the small tube that sits in the pilot flame and runs to the control valve.
there are two ways, increase the pilot pressure if possible or redrill the pilot hole with a specialty set of orifice bits...many times its easier to order the orifice youre l…ooking for

You turn the regulator to OFF, wait 2 minutes, then turn it to 'Pilot' and depress it. Have a long match as is used for BBQ's , reach in and hold match where flame shield is a…round pilot. It should light immediately, BUT keep holding the button depressed for 2 minutes. If it goes out when you release the button then you have a problem with the thermocouple and the easy solution is to change it. Your appliance might have a built in piezo ignition (spark), if so there is no need to use a match. Follow the steps above, not using a match and you should press the "spark" button to light the flame. You should hear a click, click sound from the spark, then after about a minute, release the button and turn it to 'ON' - you should now hear a whoosh as the gas ignites. Keep your face away from the appliance for safety reasons.
