The Dealers in California are supposed to set the systems to specific regeneration efficiencies.
The real problem with this hyper efficiency claims is that as with everything else, nothing is free. You dont get 5000 grains effcieincy without giving up something else. Without going into a long and boring technical training seminar, I will just tell you we are working with a customer that is one of the biggest manufacturers in Europe for the ultra efficient systems. They are working with us right now to try to solve their resin issue. They are having constant resin failures in under a year. Resin in a system that does not get these hyper efficiencies can last for decades. We are trying a few tricks to try to hide the problem, but the problem is ver obvious and not fixable without a major redesign. For now, they are just accepting that 10% of their equipment will have problems in a year.
As to the bleed through issue, water has too many variables to accurately do this. Water with sulfates, chlorides, sodium, etc all have different feels, and no two water supplies are alike. At my house by the beach, my softener maintains less than 10-15 ppm hardness, it feels great. My house in the Inland Empire, the water does not feel soft unless the ppm remains below 5 ppm. That is why the silly blanket absolute statements made on this forum show a persons lack of knowledge. The lack of field experience, and the comments of" ive always done it that way" are comments we here from first week trainees. The people who post on here almost always have excellent questions, and are looking to gain a knowledge and deeper understanding of their equipment so that they can maintain and even adjust their equipment because they bought it over the internet without having a proper water analysis done. This forum has many highly qualified people who all have their specialties. From guys who can rebuild Kineticos or Culligans in the dark, to licensed plumbers who also are very knowledgable of modern water softening equipment, to the technicians like me who work first hand with this equipment everyday for a living.
17 minutes regen time... I dont want to discuss this in a forum. Please send me a pm if you want more detailed information about that design.
