    I am having a problem this year with 12" RB T'40's & 5004's. For winterization, we "step them down" while air pressure is running through the heads - just like we do for a 12" spray (1812). This ensures that if the side inlet is used opposed to the bottom inlet (which is more that often the case), water will not remain in the bottom of the head & crack the casing. We have been doing this for years. This year, while doing start ups, I am noticing that a lot of these 12" rotors are no longer rotating. Some of these heads were just installed last year! I have a suspicion that their not working has something to do with stepping them down with air pressure. If anyone else has experienced this, or has another solution for getting all of the water out of the heads let me know. Right now, I feel damned if you do - damned if you don't.

    There it is, and otherwise, if it's not your install, wait till they break, and re-install the broken one properly!!
