    Thanks for the info about downtown where I refuse to work. (No parking)
    That's what I have, a regulator right after the riser to a 400kBTU meter and 1" into the house.
    The gas line from the tap by the road is probably 700' to the meter. I asked them to run an 1⅛" line. That way if there is a problem, they could chase it with a ⅝ line and still have enough gas @ 5psi. They did.

    Seams it has to be a low pressure system serving 10-12" wc and more then one regulator pit failed. Anxious to hear what actually happened.

    Our local paper is saying that a control room in Columbus is being investigated because they should have been able to see the overpressure, and perhaps had some control over it as well?

    "The federal Pipeline and Hazardous Materials Safety Administration has reported that the pressure in the Columbia Gas system should have been around 0.5 pounds per square inch (PSI), but readings in the area reached at least 6 PSI — twelve times higher than the system was intended to hold," the letter said.

    If you can't fix it with JB Weld, Duct Tape, and Ty Wire it has to be replaced.
    No good deed goes unpunished.
    If you want to take off friday to go fishing then make sure you train your helper right.
