My pilot light on my water heater wasn't coming on. I replaced the thermocouple and it didn't fix the problem. So then I bought a whole pilot assembly with thermocouple, pilot tube and igniter all in one. I installed that and the pilot came on and held. When I turned on the burners they worked for about 10 seconds and then it all went out, burner and pilot. Now the pilot is not wanting to come on again at all. What else is there that I can do? Side note: drip pan is full of water.
