How many other manufacturers’ lines does CalTech Water currently carry in California?

As of the writing of this answer, CalTech Water is currently in negotiations with six manufacturers and expects to have no more than three exclusive lines throughout 2018. With that said, if is more important for us to recommend the right product for your water treatment application – so we work with just about any company that has what you need and find that almost all of them will work with us. We are not “pushing” a brand for all applications.
