Ion Exchange — leaking multiple valve

I purchased a Water softener from the Worlds No.1 co. in this
feild only to find that after 19 months of purchase the multiple valve has broken & has to be replaced.What about the quality
of components you use or you are simply putting your stamp
& making a killing of the brand name you enjoy.
