Just so everyone knows you guys are on the top of google searches when you type in "EasyWater review" which may be why this thread is getting so popular.
I'm a water softener professional and have been for several years and I'll tell you that this "EasyWater" system is a complete scam and isn't the first one I've seen. There are lots of companies that come in and try to put us out of business with their "wondermagnet's" and "easywater" systems. I've noticed that they are never around for longer than a month or 2 and when they leave I'm the one that gets paid to remove all of their piece of garbage systems and put real tried and proven water softeners in.
As far as the Culligan water softener systems I can tell you yes, they are in the business of selling salt so they program the units to use much more salt than necessary. Trust me it's the easiest thing to do and if you all want I can explain it to you.
The most efficient system you can get will cost you around $1,500 but it will use far less salt than any other unit. They are assembled by professionals who measure the amount of hardness in your water and adjust the softener to use only the amount of salt necessary. For example I, living in the desert in Arizona, have real crummy water at my house - to be scientific our water has 40 grains of hardness. Culligan and other companies program their softeners to remove 60 grains of hardness but that's the worse case scenario of any water in the nation. Most city water will have about 20 grains of hardness so, if you do the math you are using 3x the amount of salt necessary. That's why generic water softeners are a joke.
This is how the real water softeners look:
Anyway, I'm not here to sell softeners or anything. I'm just here go give my advice and share my knowledge on softening water.
Let me know if you have any other questions.
