I want to thank you for the work at my house on 7/31 and diagnosing the low gas pressure. Based on your advice I e-mailed Washington Gas Customer Service that afternoon had an e-mail back the next day setting an appointment for today. Today a contractor came to the house, said the system was a split system because of the original HP line to the fireplace but did not need to be any more, removed all the old regulators and meter and replaced the old exterior 5.5 IWC regulator with a new 7 IWC regulator. It seems that the issue is solved, but I never would have gotten there without your help and analysis.
Thank you.
