| 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. | Sold as an 8-year limited warranty, prorated: parts free in years 1-2, then supplied at 40% (year 3), 60% (year 4) and 80% (years 5-8) of base price. No labor or shipping. DIY installation keeps the warranty. Commercial use: 1 year. |
