This kitchen gas line was flexible and going into what appears to be a schedule 40 pipe. I have not seen this before. Home built in 07. Is this ok?
Is it used as a chase?
Looks like someone ran 1/2 inch CSST from the gas stub through PVC. Does it go to a BBQ or fire pit?
I don’t know if CSST is rated for any outdoor installations. I’d write it up because it is non- standard, and you don’t know how deep it is. Gas is usually required to be 24" deep.
