After shopping around, I purchases a system from Rain Water Conditioning of Las Vegas, and the process was so professional with them. They were happy to answer all my questions, over the phone, including pricing. I went to their showroom on Decatur to see the equipment, and I met the owner in person. He was no-pressure, and very helpful. The technician/installer Joe has decades of experience in these installs, and it showed. I am glad I shopped around and didn't fall for aggressive sales approach that Kenetico (and others) tried.
