Growling

I need help! Let me explain what's going on and maybe I can find someone with a good explanation.

Yesterday morning I got up as usual and was reading the morning paper when suddenly I heard a growl. Then another, and another and probably ten growls, all tolled. So I had to investigate. No human or animal was outside, and there were no cars being used by the neighbors.

So I figured it is the furnace or the gas hot water tank, and I went down the stairs to the basement while the growling continued. It wasn't the furnace, but it did sound like it came from the hot water tank. As I bent down to turn down the gauge, it gave me one more little weak growl and that was it for the day.

Of course I called the city office and asked them to send someone out to check on my water heater. They came out very promptly and checked out the tank and the furnace very carefully. They showed me my dirty furnace filter, and I promised to buy a new one soon.

I was relieved that my heating system and water tank were in fine shape, but still I wondered what this growling must be.

So the day passed and so did the night, and as usual I got up very early again (5) and started to make my coffee.

Then I heard three growls!!

So down the basement stairs I went again, but there were no more growls.

I will have recording equipment set up tomorrow morning and by golly, I will find out what is going on!


Stay tuned!
