Suggest you ring him and say you want some money back off him because the bottle is only 3000psi not 4500psi. If he does not agree then name and shame. Also get the reg checked because if it is 4500psi then you really need to get it of that bottle and buy a 4500 to put it on.no,i better not.I would like to think it was a mistake.The guy told me they dont make 3k fibre wrapped bottles so I dont think he told any lies.Just have to put it down to experience(again)
You say put it down to experience, i'd rather cross the M1 blindfold. The consequences of filling a 3000 bottle to 4500 psi without burst disc protection does not bear thinking about.
