My boiler salesman also sells water treatment systems. I asked about a water softener and he suggested a product called the Zilmet active flow.
He said he's had good luck with them and the cost is low enough that it's certainly not like he's trying to make money on me or he'd have sold me a softener.
When I look at it, it looks like snake oil, but there's people saying it worked for scale reduction and water treatment.
Ever seen anything like it?
