Carl, I'll bet that your pulleys are slightly out of line. The proper belt
tension (i.e. 3/4 to 1 inch play on the longest part) works well when the
pulleys are in line.
I haven't changed a belt in 5 years - since I found that the front mounting
bolt on the generator was rotating and wearing down in diameter. This caused
the front of the generator to drop a VERY small distance (almost not
noticeable but enough to cause rubbing of the belt and then belt failure).
If any of the three pulleys are bent or misaligned that is what will happen.
Loosening the tension could result in slippage and less water flowing or less
generator charging.
Cheers.
