Question about Water Heaters
The pilot light on my gas hot water heater always goes out over night. I re-light it in the morning and it stays on all day and evening whether i use water or not. I have replace thermocouplers a few times and it continues to do the same thing... i have no problem lighting the pilot, but something causes it to go out between evening and morning. what the?
Look inside the water heater when it is heating the water, the flame should be blue. If it has yellow tips on the flame, it needs an adjustment to the air shutter. There is a nut on this air shutter to make this adjustment. This adjusts the air gas mixture. You may first try just simply tapping on the burner lightly to loosen any debris that may have built up and vacuum it out. MAKE SURE YOU TURN OFF THE GAS BEFORE CLEANING THE BURNER!! Also, check for drafts that may be blowing out your pilot light, Furnace register or outside drafts on windy nights. Some water heaters have an automatic shut down if the water heater gets too hot, so don't have it set to its hottest setting. Most water heaters only last about 10 years or so, It could be you are ready for a new one....Joe

Do you have Natural Gas or do you use Propane?
There should be a shut off valve within 6ft of the gas valve on the heater, turn this off. Also, you should turn your gas valve to the off position on the heater itself.
Then, remove the burner assembly and make sure that there is nothing clogging any of the feed tubes.
Put everything back together and see if it operates properly.
If your Heater is hooked to "Public Utility" natural gas, you may have to have the gas company check the pressure within your home.
When everyone gets up in the morning to go to work, they all jump in the shower at about the same time. On rare occasions, if the pressure to you house is not regulated correctly, this can cause a pressure drop and the pilot will go out.
Water Heaters are one of the last appliances to have a standing pilot. Most boilers, stoves and other gas appliances sold today have electronic "spark" ignitions that will light the burner element on demand.
