During the Texas Freeze two months ago, we lost power and everything froze. I didn't think to shut off the breakers to my pumps, so when power came back in the middle of the night 16 hours later, the pumps came on. Seven hours later, I walked out and heard my pumps screaming and sounding like they were tumbling rocks, and shut the breakers off. Then we lost power again for another 12 hours. Four days later, when everything thawed out, I turned on the pumps and everything worked! My waterfall pump was a little noisy (squealy), though. After a couple of weeks it quit working. When I turned it on, it hummed, then shut off. I finally got around to swapping out an older pump to get the lines flushed out (algae was starting to build up), and took the bad pump apart. Everything looks good, but the shaft on the motor will only turn back and forth, about 10 degrees. I haven't disassembled the motor, yet. Should I assume the bearings are bad and replace them? I already know that the mechanical seal between the motor and the impeller took a little bit of a beating, so will replace that. I'm just wondering if I should just shell out the $200 for a new motor - this one is less than 3 years old. Thanks for any insight y'all can lend...
