My previous post regarding *extremely faint* high pitched
sound coming from my hot water heater incorrectly stated:

"...I then noticed that when I touched/bumped/jiggled the, "relief
valve,"
pipe coming out of the side of the hot water heater, the high-pitched
sound changed a bit...."

Actually, touching/bumping/jiggling the "relief valve" does not affect
the sound one bit. The sound is so high-pitched that just the act of
reaching over in that direction made my hearing point in a different
direction, thus modifying the sound.

I have determined that since the sound is 24/7 ("all the time") and
"seems" to be strongest near the temp control dial, that it must be the
sound of the gas flowing thru the pipe. Why it makes a high-pitched
sound instead of a hissing sound .... I don't know.

Any thoughts?
