pilot light on water heater
There are a number of potential causes of a pilot light on the water heater not staying lit.
If you are noticing any sooting around the water heater vent, it is possible that a mud dauber or spider has built its nest in the air tube for your heater - - removing this device (it is held on with one to three set screws depending upon the water heater model) and cleaning with a soft bristle bottle brush often solves this issue quickly.
If the air intake adjustment is too much or too little, this can be a problem - - on my Atwood, it was a cage like device that could be rotated once a set screw was released to increase or decrease the combustion air intake.
I have also found that it simply is a function of the prevailing wind when parked at certain sites that results in the pilot being blown out as soon as the burner kicks-off when temperature set has been met.
I am sure that there are other causes, but these three are ones that I have encountered.
