What is the expected life of a Hot Spring E5 circulation pump, I ask because I just had one fail after just one year of service. It looks like the impeller seized on the small white bearing, and the metal stem ripped out of the pump base tearing out small amount of metal (head of a pin size bit of metal). I have to wonder if the failure was caused by my ozonator as there was brownish gunk on the white bearing surface under the impeller.
