Thinking of getting a water softener

We use the Flo Pur RV Pro 10000 water softener. As already stated, it used 2 pounds of ordinary table salt to regenerate. The only issue we have had was with the plastic Y at the outlet port. It broke and we replaced it with a metal one. You flush it after regenerating so there should not be salt that would eat up your drain plug. We put a Y just before the hose goes into the water softener and I get drinking and cooking water there. Some people do not worry about the trace salt in the water. It is the same issue when you use a water softener at home. After we started using the softener, we do not get all the water spots and scale we used to get using the hard water out west.
