Their shoddy installation near Dallas Texas ran lines from outside the garage to the inside in insulated. They froze which stopped the trickle flow and then froze the softener itself. Tank bulging in several places. Now they want over $1500 to rebuild and replace. It's nice to build in a failure so they get paid all over User's recommendation: Don't let them do anything. Get reputable plumber to pipe and insulate. Past GE unit used a third of the salt so buy elsewhere.
