I've been noticing a strange low pitched noise/vibration in my home,
that I was able to determine only is occuring when the gas water heater
is firing. At first I could not determine where the noise was coming
from at all, it sounds pretty non-directional. In the basement it
sounded like it might be upstairs and visa versa. Finally I was able to
hear the noise very loudly by the gas meter outside.
This appears to be the source of the noise, or more likely the circular
regulator just before the meter. The noise then reverberates through
the house via the black iron gas line that leads to the furnace & water
heater. I suspect the noise will also occur when the furnace is
operating, but that is still out of season.
Before I call the gas company [Keyspan Energy- New England], has anyone
experienced this? Is it just a big annoyance or could it mean
trouble. Also, is the gas company responsible for the equipment before
and up to the meter if the meter is outsid ths house?
