Do yourself and favor and do your own research before overpaying for this system. I have had my system for almost two years and the water has only gotten harder since having it installed. Now that the Leaf system is being ripped out and I've started doing my own research, I am finding that I can purchase a system for literally 5 times less than the one I purchased through them. My neighbore paid less than $1,000 for his and he has not issues. When I purchases the system from Leaf I already had a water softener system, but wasn't happy with it because we still had white sediment all over everything. I was sold on this system by Leaf and as I said earlier my problems only got worse. I am grateful that they are now refunding my money and removing the system, but now I'm stuck purchasing another system, even though I had one that worked better than this one prior to purchasing the Leaf System. The technicians that came and serviced my system over the past two years had no idea what they were doing. My new roommate, who happens to be one of those people that don't stop until they have a solution, was able to figure out that the system wasn't working. I am rating them a 2 only because they are doing the right thing in refunding my money, but in my opinion they should be offsetting the cost of a new system consdering I ripped mine out to install thier system that didn't work. Not to mention, the damage this has done to my appliances etc... Do yourself a favor and choose a company that specializes in water softeners. Leaf does not.
