During my last brew while I was sparging my Chugger Pump started seizing constantly. It would start making a horrible noise like it had lost prime. I would turn off, prime, and when I would turn back on the motor would not start. I checked every connection multiple times. After a few minutes it would start again. It works great for pumping cold liquid but seizes when pumping sparge temps. Chugger says to send it back for evaluation. Anybody else had this kind of trouble with theirs or am I the lucky one?
