Jer,
 
Have you also taken into consideration that it may just be the composers (and/or publishers) fault why strings keep breaking and not the professors?  I mean, when you come across an "fffff" marking, it is not to be taken lightly  :-).

Watch him play.  Find out how hard he plays and what he plays to make it break.  Don’t say anything about suspecting that it might be HIM that is the problem because he may just set back and not play as hard then.  Ask what happens at that point when it breaks.   Chances are, my guess, would be that it is him that is the problem in one particular song that he likes to play.  I run into that frequently at my college when one particular professor is practicing the same song over and over and over again for a recital or concert.  She’s broken the same strings on the same song yet, when she changes songs, the strings stop breaking.  She has a VERY hard touch and this is what is causing it and she knows it.  I’ve tried replacing with smaller and, larger diameter wires. It makes no difference in her case…

I have been servicing a 2001 Petrof vertical since 2006 with no problems. In Aug 2010 my customer called and thought a string may have broken. It had and I replaced the string (#14 1/2) and tuned the piano. I tuned the piano again in Jan 11 & May 11 everything looked good (by the way, he is the only player and plays only classical music). I just got a call that a string has broken again and he thinks it may be the same one. 
 
This piano has agraffes throughout. Any thoughts or suggestions? And if it is the same string should I go with one size smaller?
