Gas Pressure Dropped from 20 PSI to almost 15 PSI in 30 hours

[Carlos Tchinda]

I has a license gas professional test my gas pressure. After going from 20 PSI to zero in couple of hours, we changed the fittings. The gas pressure was pumped to 20 PSI then It went from 20 PSI to almost 15 PSI in about 30 hrs. Is that a clear indication of a gas leak? House just uses gas for heating.

Gas company will just come and lock your meter out if they find out your system leaks and won’t turn it back on until you have it certified/inspected. 
Everything past the meter is your problem not gas company. They will happily shut it down if you tell them it’s broken unsafe or leaking. 

Yes sounds like it leaks, hopefully the professional also told you that and is looking for the leak.

Also that much pressure is only for test purposes. The actual gas runs at about 0.25PSI, 1/4th of a psi. So low it’s hard to detect.
