I change the carbon dioxide cylinders for the third time and all 3 cylinders were bad, namely they were siphoned near the valve, I ask how you certify them if they have all the valves finished off, the second time when replacing I can't unscrew the valve, but still after much effort it succeeded, and then in a week all the gas came out, the third time when I changed , I already said on the issue that the balloon was poisoned, to which the master replied "it was necessary to press the valve with a key", and now another fiasco, the third balloon hisses when unscrewing and twisting, so think a hundred times whether it is worth contacting
Excellent service- I arrived and replaced the cylinder of the welding mixture. There are no queues, from the word at all. However, there is still one point that did not please - the underwater road and the parking lot want to be better.
