| Warranty and models | |
| Warranty | 3 years |
| Warranty terms | TradeGrade product: 3 years or 10,000 operating hours, whichever comes first, when bought from and installed by a pool professional (Plus cells). Pentair's warranty page gives TradeGrade products bought online a much shorter limited warranty (60 days on the product page; 1 year, parts only, on the warranty page), so DIY online buyers get far less cover. |

Alternatives in this pool type
Pentair’s big-pool salt system for up to 60,000 gallons, bought and installed through a pool pro.
A basic, budget-minded salt system for large pools whose owners want to avoid acid cell cleaning; the short warranty and high salt level are the trade-offs.
