Just thought I would add to the collective experience we have here.
The salt sensor failed on a 5 month old unit. Warranty repair took 3 weeks.
It has now failed again, 2 days after repair.
So far, Pentair has been responsive if not quick. We will see how the latest problem gets handled.
At this point, with the experience here coupled with my own, I would not buy another Pentair SWG again.
I will let you know the outcome.
