| Warranty terms | 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. | Intex 2-year limited warranty on the control unit and the electrode(s), 180 days on hoses and fittings; original purchaser only, the same for every buyer since Intex sells direct and through retailers. Repair or replacement after an Intex service center accepts the claim. |
