I just noticed on my natural gas range supply piping that there is no sediment trap.

The existing setup is: In a crawl space, 60 foot of CSST from a iron pipe manifold connected on the other end to a black pipe 90 degree elbow. Then a riser thru the flooring to the shut off valve for the range.

Normally, I would have thought there should be a sediment trap at the point where the 90 is currently in place.

Is this pipe run compliant with code?

Thanks!
