We installed a Culligan softener. I was not here when Culligan installed it and nearly fainted to see it was set up to backwash into the basement sump pump, which is there simply for the whole basement dehumidifier to drain into, and which empties out onto my precious lawn. We are on municipal water and sewer. Culligan, who I would NEVER recommend, tells us we need a plumber to address this. The plumber talked like this was a really big deal, p-traps and airlock, etc., etc. and hasn't shown up, even though he said he would when he could get to it. I am sick of waiting. What's the big deal? Can I just find a handyman who does bathroom remodeling, which includes plumbing. I don't want to kill my lawn, or wear out that tinker toy sump pump, either.
