Checked around to look at am variety of water softeners, Terra from Clearwater came and did a water test we tested a 10 plus for hardness, she showed me what was available from them and I picked the one that I liked, they set an install date tony was the installer, I told him I had Pex piping and I wanted the crimp on connectors, I didn't care for the push on ones, He did an excellent job on installation, I stayed with Clearwater because this is their business, reviews were outstanding. Thank You you have a customer for life.
