Marty's logic is sound, though he left out one detail. Pentair gear carries a 60-day, or 1-year or 2-year warranty, depending on which product and who installed it. But if the PB installs three items, all purchased on the same invoice, you'll get a three-year warranty on everything. Those three items come from a specific list, not just any three items.
I'm coming up on three years. I've had two SWGs go out, and one 5G light. The second 5G is going out, too. So about $2400 or so? I haven't done the math to see if that has penciled out. And I would say pool gear is somewhat outside the scope of the normal warranty logic, the one where it's said "If it makes it through the first week, it'll last forever." Pool gear is in a harsh environment for electronics, and I believe it can go out at any point.
It's a role of the dice either way...
