Water break?

[BSBAL18]

3rd inning. Pitcher has been going long time in the 90 degree heat (probably 40 pitches in one half inning). He calls time and asks for water from dugout. I allow it. he takes 2 drinks and gets back to mound quickly and resumes play.

Opposing coach goes ballistic on me stating "did you just allow a water break? Ive been coaching 35 years and never have i ever seen that". He continues to make remarks throughout the game regarding "so if we walk the next batter can my pitcher get a drink?".

I was not going to be that umpire who didnt allow a kid a drink of water that then passed out or something.

This was a 14u REC league game. However, woudl this be allowed in NFHS playoff game/etc? I know being rec i "relax" some rules, but i couldnt find one about "no water breaks". I told the coach it was my judgement and the pitcher didnt lollygag or anything and was quick.
