The jug will be ruined if the valve isn't fixed. I would try to get a look at the valve seat before pulling the jug but even with a good borescope it can be difficult to spot what is causing the problem. A valve can be lapped without pulling the jug but if the seat is actually bad or the valve burned then the cylinder must come off for repair.
