Our customer in Weaver Alabama had an old RainSoft water softener that was installed in 2003. It needed a new computer board and other repairs. Rather than spend hundreds and hope nothing else went wrong with it, he decided to upgrade to a new SmartChoice HE water softener with a whole house taste and odor filter. It fit perfectly, out of the way in his crawlspace. Thank you for your business Mr. M., Weaver Alabama.
