| Warranty and models | ||
| Warranty | 3 years | 2 years |
| Warranty terms | 3 years on the dealer-sold versions (AQR3XLCUL and siblings) bought from and installed by a pool professional; the online-sold W3AQR versions carry 1 year (manual, effective 03/01/12; Hayward's W3AQR15 page: 1 year parts, no labor). A replacement W3T cell bought alone carries 3 years parts. | TradeGrade product: 2 years or 6,000 operating hours, whichever comes first, when bought from and installed by a pool professional (LT 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. |
