Reason being there were some metal plugs or something in the little holes coming out of the burst disk. Apparently if the disk blows these fragments are shot around the room and can cause injury. The shop owner who I knew reasonably well (so I hope wasn't spinning me a line) showed me a small number of older valves (not just j valves) that were no longer "legal". I dare say if I'd taken the tank and valve away with me I could have got it filled elsewhere (I noticed the other day after a fill that one of my tanks was about 4 months out of test, woops!!) but I replaced the valve anyway ($60 is cheaper than loosing an eye). I kept the j valve as a spare. Anyway I thought it was worth a mention. The tank and hence the valve is about 16 yrs old so knewer valves or other models probably aren't a problem, may be worth checking with a reputable service provider though (sorry I can't recall the model/brand). As an aside I can't remember why they're called j valves, there more of a "t" shape.
