Second trial and the little thing is not able to push more than 50 PSI into the tube (700x23c), it doesn't seem to be broken but the piston goes up and down and very little or almost no air is going through the valve. Nothing wrong with the valve as I have done previous tests with 3 other pumps and have pumped thousands of strokes without a single issue with the valve or tube. (As you can also see with the other pump I used in the sequence of the same video)
