Replacing your IntelliChlor only to find out it wasn't bad isn't the worst thing. You use the second one first, until its warranty expires, then either continue to use it until it's done, or go back to the first one. You'll have a backup until one of them is finally finished, and then the backup one can come online. They're expendable. Not unlike buying extra gallons of chlorine, except the chlorine "stored" in an SWG doesn't go bad.
And while SWG prices might come down after supply chain issues resolve, I'm guessin' they won't. Now that corporations know we'll pay these prices, there's not a lot of incentive for them to give them up. It's more likely SWG prices will continue to rise, and you'll have a "bargain" in storage.
I replaced an IntelliChlor that had some issues, even though it still makes chlorine. I replaced it while under warranty, while I could. I'll reinstall the old one when the new one is done, and in the meantime I have an "emergency" SWG waiting in the wings.
