water softeners--why a company vs. basic one at a home depot?
i did a quick search and didn't see this discussion, so please forgive me if it's already been discussed, but why does it seem everybody uses one of the franchise-based water softening systems, like culligan? the house we bought a few years ago came with a culligan system that requires us to have maintenanced every year (and also happens to be 25 years old, so it flushes a ton of water every night, no matter what our usage).
it has finally died and culligan wants thousands of dollars to replace it w/an updated system. home depot has several for under a thousand bucks. is there anything wrong with these water softeners?
