Bead, doesnt Pentair warranty for 10 years if the heater and filter are theirs? I know it is nearly double if you have booth.nope 3 yrs as can remember . now the shell of the filter is warrantied for 10 ( upper & lower tank only). i had customers that had problems with their heaters after the warranty was up and they either fixed or replaced the heater at no charge. now this was shortly after the warranty was over , like a few months . not years.
