I also have the same problem, I got 2 Tunze 6045 that the shaft rusted and broke, they only lasted me a couple of months, I bought them brand new from Premium Aquatics, got really mad about them that never bother with them anymore, I called Premium Aquatics like a month ago to see about the warranty but they updated their computers and don't have any info on me anymore and I didn't keep the invoice, there at least a year old, also the clip that hold the pump with the magnet when moving the pump I broke the eyes on the clip that holds it against the magnet, now my question is there anyway I can get the shaft and the clip for both? Thanks.
