What is the 12000? Is that waveline? My issue is the impeller seizing and it doesn't appear to be precipitation on the bearings. I always have to manually turn the shaft in my hand a few times to loosen it. I do soak in vinegar for a few min too but I'm always in a hurry to get my system back online.
