My SC-36 cell died after 3.5 years. I have a 15,000 inground. I live in Phoenix so the cell is used year round, so I am trying to decide if I should upgrade to the SC-48. I am not sure if 3.5 years was the average life span of a SC-36. I know for the first year I didn't understand pool chemistry as well as I do now and I think I may the cell work harder then it needed.
Any thoughts..is it worth the extra money to updgrade?
