Isn't that a pain in the "Gas"... Sorry
The valve handle could be backwards...maybe. But here is another factor. These valves have a taper "cone" inside the body which is fitted by using a super fine crushed glass power when "mated" together during MFG.. ( My dad used to make these at one point.) There should be a nut on the opposite end of the handle to tighten the valve... if this is the type of valve that I am blabbing about here. Since it is not the job of HI's to test valves I can only say to the client if the handle is very loose in the housing two/ three things could be happening here . 1) The handle is loose on the stem. 2) The handle it tight but the assembly in the valve is loose so the nut could be adjusted. 3) The hold valve is shot and letting gas flow...

and dang it just change the darn thing...
As for the flex pipe in the housing... A no no around here.. From the metering valve to the exterior should be solid pipe (could have elbows and such) and then flex pipe is "somewhat permitted"... after a drip leg on the "black gas pipe"..
