I have a Hot Water heater, that has an Always On nat gas pilot light.
We live near the ocean side, where 35 MPH winds are quite common.
Depending upon the wind strength and direction, the wind will on
occasion blow out that pilot light. My wife sure lets me know, when
she encounters a COLD morning shower. This happens ~3 -4 times a
year, still a PAIN!!

I have searched the net, and asked a plumbing supply sto "Is there
a vent/ exhaust stack cap that I could put on". My idea is that cap
would automaticcally rotate/adapt to the direction of the wind. The
cap would in effect prevent (most of) the downward draft wind, into
the exhaust tube, from "blowing out" the gas pilot.

Does anyone know if theere is such an item that I could add, to
prevent the wind from killing the pilot?? I sure would enjoy NEVER
relighting that DA*N pilot! - rob

BTW: I have found one plus. Today the pilot (15 year old HW heaater)
would not relight. A replacement thermocouple resolved that issue. I
did find a lot of rust debris, upon the buirner element. Further there
was also a small amount, on the area where the pilot light is. After
cleaning all debris, it now seems that the pilot light is "more
robust"?? I may have thus lessened how often the pilot fails???? For
sure I now have a more effective burner, w/o that debris!

You can obtain an automatic pilot relighter from your local HVAC supply house, W.W. Grainger, Johnstone Supply, etc. The unit has an electrode that extends into the pilot flame and senses whether or not it's lit. If the flame goes out, it starts producing an electric spark to relight the flame before the thermocouple cools off and closes the gas valve. I installed a lot of those kits to take care of problems just like you're having. ^_^
