I'm doing a gut renovation on a 2500 sqft house. I hired a plumbing company to replace all the waste lines, gas and water.
The job is taking twice as long as it should have and I'm completely fed up with them at this point. They tested out the gas lines with 15psi of air pressure and said it was good and I should call for my rough in inspection.
The next day next morning the gauge was at 9psi. I went through all the connections and found a leak at a connection on the black pipe. They came back and fixed it and pumped up the system again and now 36 hrs later its down 3psi.
Why are gas lines tested with such low pressure? I understand gas comes in at 2-4 psi, but if water lines can hold over 100psi, why not gas?
I'm in Los Angeles and I believe code is 15psi for 10min.
Should I be concerned about loosing 3psi over a 36hour period? To me that indicates a leak
The gas is a mix of Black pipe and Trac pipe, there are no appliances installed, everything is capped and it is not hooked up to the meter yet.
Any thoughts on this would be appreciated?
