| Warranty terms | Pentair's US relaunch page gives the reintroduced IC20/IC40/IC60 a 3-year warranty when bought through a pool professional. 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). |
