Don't know if this was discussed here before I was around. Worth mentioning. There were a bunch of defective flex NG hoses on the market. Those hoses are most common on ranges and clothes dryers. I replaced the ones in this house with new hoses because I didn't know how old the hoses were. Can't find anything about it now. About 10 years ago. I'll bet there's plenty of those bad hoses out there waiting to fail.
