Oh so annoying! I had called the plumber because it was getting to where
our replacement water heater had to be lit once a day. Initially we had a
new one installed on New Year's Eve, 2009. It worked for a while but then I
had to keep relighting it. At first it was perhaps every three months, then
every week then like every half an hour.
They never could find out what was wrong with it. They replaced every part
they could and finally just gave us a new one. And it was fine at first.
But the same problems started happening up until now! I just relight it
perhaps 2 hours ago when daughter took a shower and ran out of hot water. I
had gotten to the point of being OCD in checking it to make sure it was
still lit. And it had been the last time I looked. And even though it is a
50 gallon tank, apparently when it goes out, the water cools very quickly.
So I relit it, called the plumber because it was getting to where I had to
light it daily. Plumber asked me some questions about it and I had to go
out there to look at it. And it it wasn't lit! So it went out less than 20
minutes after I lit it. And now it won't light at all. Grrr... Grrr...
I am sick of this. And they can't do anything about it tonight. Guy said
he could come out here but I would have to pay $150 just to get him out as
it would be after hours charges. But he had no clue whether or not he could
do anything about it tonight. So... We wait.
Only thing I can figure is that it might be the venting. That is the only
thing they didn't check. They did say that the last one wasn't drafting
properly or something like that.
I thought maybe that it had something to do with humidity. We had a few
humid days lately and it seemed to go out when it was humid. Then the
torrential downpour throughout the night last night that knocked the power
out. Amazingly enough the thing stayed lit through all that.
For now light a candle and stick it in the burner chamber, does it stay
lit? If so, gas sup[ply is OK?
Venting or gas supply, what else could be the trouble?
How is the venting done? Tied into furnace stack or all by itself?
Often we tend to over look most simple basic things experts do that all
the time too wasting time.
What kinda chimney?
I agree that venting may be the problem (bird nest?) but usually, it
would light and then go out once the burner was on. Could be the
overheating burned out the thermocouple or something though.
Be sure they check the vent at both ends and run something through it.
They are working on it now. There is a bad part. Something to do with
letting the gas in. Also the venting may not be right. They were given the
International venting code but the guy wants to check the Washington Code
before doing anything because changing the venting will be expensive. There
is no Thermocouple on this kind. It's newer. It has a Thermo...something
else. Can't remember the name but it's fine.

We went through this same situation with Julie months ago. Suggestions were
made about checking the venting, how it's vented, any wind blowing into garage
where the WH is located, possible bad thermocouples, ie all the obvious things.
As I recall, the TC had been replaced at least once and the gas control valve
had also been replaced. And I think it happened
with the garage door open or shut, ruling out some sudden gusts blowing into the
garage. I don't recall hearing how or if it was resolved then. But it's kind
of surprising that she would pay for a plumber to come out, again, and still
no one has checked the venting? How about some pics at least of the venting?
IDK exactly how venting could cause this either. Even if the vent were blocked,
the pilot light wouldn't go out. It doesn't even need the vent for the pilot light to remain lit. For it to go out, I would think it would need the
venting to be arranged so that somehow it results in a sudden gust hitting the pilot light. I presume the pilot orifice, tube between the valve and orifice have been carefully checked?
If she can't find someone competent, then the other option is to just bite the
bullet and get a new WH, one that doesn't use a pilot light.

a realtive of mine had this problem, turned out to be low gas pressure in her neighborhood, it was a intermittenly bad regulat owned by the gas company.....
this occured many states away so i am sorry but lack details.
OP should call their gas supplier to get the homes gad pressure checked.
simple stuff can screw stuff up.
my step sons van broke down. he called me in the middle of the night saying it just quit. The gas gauge was flakey in that van, but he assured me it wasnt out of gas.
van got towed to garage I told the garage check to make sure it has gas..
880 bucks later with a new battery and new fuel pump, the garage gave up and said we dont know whats wrong.
hadvan towed to dealer, they were very busy. van sat for 5 days..
dealer noted gas gauge showed empty, put in one gallon of gas, van started right up....
van ran out of gas, stepson and garage didnt catch that van was out of gas.
dealer was nice only charged for gasoline..
I had two similar moments. One time I took apart a
carb on a friend's car, looking for the clog. Finally
noticed the absence of gasoline.
Second was when I stopped to help a guy with the hood
up, in a parking lot. Truck was only a couple days
old. Didn't want to start. Asked him to check the gas
gauge.... add gal of gas. There was a gas station a
couple hundred yards away.
Back when I was a young 'un, I drove an old beater with an unreliable
gas gauge. I got in the habit of setting the trip odometer every time
I filled up and noting the miles I'd used on that tankful. I knew when
I'd put about 250 miles on, it was getting close to time to fill the
tank. It's now a habit. I never look at the gas gauge, I check my trip
