    Gas line testing
    What are the basic requirements for testing propane gas lines. What pressure do you have to use and for how long? I have a new propane fireplace. The propane company will not deliver because they say there is a leak, but the installers say they tested the system and show no leaks. Each side has been out two times (at my expense with the propane company). The propane company uses some sort of pressure gauge and they are detecting a leak. The installation company uses a smaller gauge and also a "sniffer" and detects no leak. I am about to give up and have a third company come in (at my expense) and go over all 100 + feel of piping inside and out of the house with at least 17 elbows. If I knew the basic requirements for testing and pressure checks, I think I might be able to force the issue with the installers. Thank you!! K

    You can take this http://www.cctexas.com/files/g33/FUEL%20GAS%20CODE.pdf

    For the relevant sections and look at the sticky in the electrical section. From there you should be able to locate the National Fuel Gas Code and read it online.

    As this states, the AHJ (Authority Having Jurisdiction) can make changes.

    With the right electronic sniffer, you can detect extremely small propane leaks. Example: INFICON DTK706-600-G1 PROPANE GAS DETECTOR

    Your plumber uses regular 15 lbs gas gauge widely used in testing natural gas plumbing systems.. Your propane company uses Mano-gas-gauge. Mano-gas-gauge is extremely sensitive to pressure drop. Drop in pressure that shows on Mano-meter will not even register on regular gas gauge.
