The only places I know of that sell salt systems are discount salt pool, Polytec, and Inyopools. I've personally used all three and recommend them all for anything they sell. All three seem to have a good reputation here for honoring warranties and customer service. I know discount salt pools has replacement cells for IC 60. Not sure about the others. They also have a great reputation on here as does Pentair. I think you have a couple options:
- See if your eBay source will make an exception on the warranty for the "water in cable" issue.
- Replace the cell using Pentair replacement with authorized supplier/installer and get full warranty.
- Replace with a reputable replacement 3rd party such as Circupool with their full DIY warranty.
- Take your chances with an eBay or other again. Warranty questionable.
If your supplier won't play ball then I think the next two choices are much preferred. The warranty issue is especially important with salt cells. All manufacturers have some failures that don't become apparent in the first year and this is expensive to fix out of pocket.
I hope this is helpful..
