No store we check sells it online; the maker lists where to buy or who installs it.
Pros
- Plus warranty: 3 years or 10,000 hours when installed by a pro
- Shows the salt level in ppm and shuts off in cold water on its own
- Certified to NSF/ANSI 50 and works with Pentair automation and app
Cons
- Needs the PC100 power center, sold separately online (about $450)
- Hard to find in stock online; Leslie’s lists it as out of stock
- Bought online, Pentair’s warranty shrinks to a short parts-only cover

| 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. |
