Pros
- The most common SWG in the US — its T-CELL-15 is the one part every pool store and tech already stocks, so service is never a problem
- Rated to a full 40,000 gallons at 1.45 lb/day output, with the current W3 (NSF-certified) controller revision
- Huge installed base and dealer network; decades of field-proven reliability
- Mid-priced replacement cell (~$1,099) sits between Pentair's OEM cell and CircuPool's value cell
Cons
- Replacement cell (~$1,099 every ~5 yr / 10,000 hr) is still a real recurring cost — cheaper than Pentair, well above CircuPool
- Older controller UX and display compared with newer DTC units
- Spec confusion to ignore: the headline output is 1.45 lb/day; the '0.75 lb/day' you'll see quoted is the derated low-salt basis, not a different cell
The pattern owners describe is failure at or just past the warranty line - a cell gone at six months, units not making two years, one reliable for four summers and dead a year after the warranty expired, a flow switch at one year and five days. Several then hit the second problem: getting Hayward to honour a warranty on a unit bought online, which is the channel trap this site documents.
