I don't own a Yugo, but I can tell you not to buy one.
Don't waste your money-way over prices and the performance of the unit is minimal. They made all kinds of promises and they try to pressure you about how salt harms the envornment. Well, I guess mankind harms the environment-the bottom line is that the units do not work as claimed. Customer service is a joke. I put a new soft water unit in my old house and it is very efficient and uses little salt. I guess the downside is carrying the 40 lb bags every couple of months.
I purchased a new softener for my sister a month ago. The on-line company I dealt with was great and he carries both salt and non salt. He was very up front about the no salt systems, how they operate and the main issue is that they are not softeners. Call around and talk to a few folks before you take the plunge.
All softeners can use sodium chloride (salt) or salt substitute potassium chloride. If you use potassium, depending on salt efficiency setting of the softener, you must increase the salt dose lbs used per regeneration and potassium is hard to find plus it costs up to 4 times what the same size bag of salt costs.I purchased a new softener for my sister a month ago.
