Strange gas noise and pulsating pressure
Last week, I noticed a strange pulsating noise I could hear from my brand new gas regulator instead of a continuous whisper. I had also noticed the stovetop burners were burning with a variable pressure that made the flame to shrink slightly and expand following a similar pulse I could hear on the gas regulator.
After inspection of the gas lines, I found out the lowest portion of my gas lines under the floor had accumulated enough black and oily water ( probably from condensation buildup in the LP gas tanks) and gas supply had to get trough this point, bubble by bubble. As soon as I flushed the lines with compressed air, normal near silent operation resumed.
Sometimes, sleeping on a problem provide an unexpected solution to a weird symptom.
