I woke up two mornings ago to water that was colder than usual, so.. I naturally went to check the water heater and the pilot was out, the pilot light has never went out in the 4 years- almost 5 I've owned it. I turned it back on and all was fine until that night, I noticed a high pitched squealing noise like pressure escaping a tiny hole.. I was pretty tired so I waited until the next morning to check it out. When I went back to finally find the source of the noise the next morning, I noticed it was louder than it was that night. I turned the pilot light off first thing, and the noise immediately stopped. As soon as I press the ignition to turn it back on the noise starts again and doesn't stop until the pilot is off.
I have no idea what could be causing it, is it normal ageing or is there a cause for concern? I've pretty much left it like that the past few days and the intensity of the sound hasn't changed but it's becoming annoying real fast.
