The water surrounded by my house is pretty hard (around 20 grain) and I'm struggling between the cheap one (650 from Sears plus installation fee) and Culligan (3000 including installation). Do you infer if Culligan worths the money? Thanks a lot!
Answers:    Buy your own; do some research, and I take in that the Sears brand is pretty good. You might also check Lowe's and Home Depot. I want one myself, but newly won't pop for it, but I've done lots of looking. Get one that doesn't work on a timer to recycle the salts; but one that monitors your usage and recycle when needed. I think you reward a bit more for it, but you're saving water/sewage costs and thinking "green". In any casing, $3,000 is grossly overpriced. Installation would cost whatever a plumber contained by your area get for about 4-5 hours plus matter; which won't be much. Remember, Culligan used to be in the "softener rental" business but can't compete beside those that sell the unit. I'm actually appalled at that price.
shop around, sear is just a baptize, and so is culligan, theres a lot better ones on the souk, try lowes, menards, home depot,
