All US Water inFusion systems have 3 main components: Valve, Tank, and Oxidation Media. Some of our systems use a chemical feed, other do not. Iron removal can be a tricky business. It's crucial that you take the time to read through your manual and watch our how-to installation videos before you attempt to install one of these systems yourself. Here you will find the resources necessary to perform all manner of technical support for your US Water inFusion. If you don't find what you need here, you can always email us at firstname.lastname@example.org or call 1-800-608-8792. We also have online-chat available from 8am to 8pm.
