I have recently discovered that the piston valves on my "just out of its one year warranty" tuba have what to me seem rather leaky pistons. I did the trick where you pull the slide, press the valve, plug the proper hole and blow method to determine this. Is it possible to fix leaky valves or am I outta luck. Matt??? Joe??? Somebody???
