Gas System Leaking Remodel HELP HELP

[tom marshall]

I am doing a remodel and re-ran much of the gas in the house. I pumped it
up with air and it held 10 lbs for two hours, much more than the 15 minutes
required, so the city signed it off. Interestingly, when I pumped it up to
20 lbs and let it sit, by the 4th day, it was down to 3 1/2 lbs. I have a
shutoff valve in the HVAC closet and regardless of whether it is in the open
or closed position, this loss still occurs. Is it normal to use air
pressure in a gas line when you let it sit for an extended period of time.
Should I be happy it holds 10 lbs for two hours or should I remove the
valve, cap it off and insist that it hold air pressure for days??? The
drywall is up but can be removed before taping and mudding. I have to have
a hairline crack somewhere but if I do it would be a nightmare to trace!
The system does seem pretty tight though and prior to the HVAC shutoff
valve put in, I believe the plumber tested it for days. What should I do?

Sounds like you have a leak.

Any drop in pressure means a leak.
A proper test would include removing all valves and capping the line. I suspect your leak is coming from the gas shut off valve.
Good Luck,

I removed the HVAC shutoff valve, capped it off and the system still loses air. Have not removed the fireplace gas shutoff valve. Is the system with no leaks supposed to hold 20 lbs of air indifinetely???????

Micheal, the gas will be under pressure all the time, you seam to be worried about this small detail, dont worry, you wont feel a thing unless the gas is ignited. But then your family might, if they live, they will talk about you in a less than nice way.
