gas leak test question joeyli2019-11-08 20:32:59

I am puzzled about the gas leak test.  AFter I clean the pilot light assembly and reconnect the tube to the gas vavle, the soap test shows no leak.  But when I try to light the pilot, I see bubbles forming in where the tube connects to the gas valve.  Not huge bubbles.

One friend (a handyman) said this is normal.  Is that right?  Thanks for your input.

 

you must fix it,not normal,change the tube or clean up the flare
