We had something similar happen. It was limited to a trailer park though. Car knocked the regulator the whole park was fed through. All the pilot lights that get .25 psig I believe were getting 60-70 psig. First due engine pulls up and parks and soon has 6 trailer burning around the engine. Pretty well emptied that particular park and as luck would have it the few trailers that moved back made the place trashier. Itkind of angers me the idiots that rode it out in New Bern then when I got bad put a bunch more people in danger to come get their dumb ***.
