    An easy way to solve the problem is to follow the lead-pipe to the first valve it enters (typically the third on a trumpet). Test fit each valve in that specific valve casing and blow. When you find a valve that has no air resistance either up or down...you've found the proper valve for that casing...Then go to the next closest valve casing and do the same....Once you have the first two down....the third is already decided by process of elimination ;)

    Be careful handling the valves....never force. Do every thing gently. Make sure they are well oiled and aligned properly before dropping them in place so you don't have to spin them if possible.

    I'd bet there are numbers somewhere on them. Even the most dullard assembly line folks would need them.

    Take an other trumpet (from a friend for instance) and compare valve by valve.

    This is exactly the way that almost all brass techs do it. It always works.

    There are only 6 possible combinations. Put a piece of tape on each valve button and arbitrarily number them 1, 2, & 3 (to keep up with which one's where) and try the combinations. The law of probability should have you hitting the right order after 3 or 4 tries, but if it takes 6, no big deal.
