Extruded Aluminum (SWCG)

PS.

We call them SWCG's here, instead of SWG's . . . since they generate chlorine, not salt

Does this help:

??

And say I go "regular" chlorine for the first year, do I need to drain my pool to switch to salt? I'm guessing not since both are chlorine, just a different way of getting it.

From a cost perspective, it's $600 difference for resin vs steel.

Average 4" in August? Wow, that's much wetter than here in Chattanooga!

That rainfall definitely puts in you in the 'less likely to have a problem' category. That said, if you are spending more than a few thousand on the pool, and want to use salt . . . I'd go for the resin (plastic).
