Gas line into the house.

[reelguy]

I have noticed a hissing type noise coming from my main gas line into the house. I actually thought it was a water line making the sound first, but later figured out its the gas line. There is no leak (or at least that I can tell) and the hissing actuall stops when the furnace runs. I've been in the house over 3 years and never noticed it before but it sure is bugging the heck out of me. Anyone have an idea of what's going on with it?

Call the gas company immediately.

do you hear the same hiss outside near the meter, or only inside?

Call the gas company immediately.

Ditto

he could be referring to the noise the meter on the outside makes when gas is going through it. mine makes a noise when the furnace is running, but i wouldnt describe it as a hissing noise though.

"the hissing actuall stops when the furnace runs"

Is the the water heater, dryer, stove, or any other gas appliance running when you here the hissing.

No nothing else is running when I hear it. And no I'm pretty confident that it nothing that going to blow up my house (famous last words!!!). i guess maybe "hissing" is the wrong word for it, but the only one I could think of at the time. Maybe its time to ask someone at Centerpoint.

Propane or Natural gas?

I was assuming propane.

Could be resonating from the main line.

I'd call up as well. My neighbor is trouble shooter for Excel, and they have people who go out on calls specifically like this. Most the time it is nothing, but you don't want to be the other 1% hehe.

While he is there, ask him to run his sniffer over your stove connections, just to be sure. My neighbor found a tiny leak in mine with the sniffer tool and neither of us could smell gas, just cause he always likes to check peoples connections when he is there. Who knows how many big problems he has prevented in the years he has done those small checks.

Good luck.
