Kinetico softener at my home has their info on it. Because I am second owner of home/system, I am not in their database as paying customer. So, they will not sell replacement drain line for product - even though I want to pay for product. Simply won't help out current owners of these very high dollar systems. And odd-ball size drain line cannot be purchased at big box stores or plumbing supply stores - proprietary drain line. Avoid Kinetico.
Edit to 2 stars: I do appreciate that the local manager contacted me based on my Yelp review. He has made SOME effort to help although it's too late as I already spent $50 "rigging" up a drain with a hodgepodge of parts. I will leave the review as originally written though as I think it's important that companies are judged on how they handle customers when people aren't looking. Not how they react when people ARE looking (i.e., how they react once a Yelp review posts). IMHO, companies reach out to get Yelp reviews edited/removed, not because they really plan to change behavior.
