Hello everyone. I searched the forum and found several helpful posts but I guess I need a little reinforcement.
I recently installed gas lines on one side of my house (black iron) and had a plumber come out and test them (before the gas company comes and does their official hook-up). He put a gage on the line coming out of the house and pumped it to 5. He told me that if that held for two hours that I was good-to-go. It held all day until that night when the temperature dipped low. The next morning, it was about 4.5 and it held that for several days. At the end of the week, it was down to about 1.5.
I pumped it up again just to check and it did the same thing -- held 5 lbs. until the night and now it's holding at 4.5.
The gas Co. man is coming tomorrow to do the final hook-up. Should I be concerned about leaks or are things progressing normally.
Thanks in advance for replying!
