Buy softener and RO?
I have approx 10 year old RO and Kinetico water softener. Both are working quite well.
Currently they are rented, and I am not enthused about continuing to pay the rent. I do have the option to purchase the units - I have not yet called for the price, but I do know it will be substantially less than new units.
I guess I am mainly wondering how long these last? Does it make any sense to purchase (greatly discounted) 10 year old units as opposed to buying new ones?
