Over time it also accumulates inside appliances and can support iron bacteria that clog plumbing. This system stops the problem at the point where water enters the home.\u003c\/p\u003e\n\u003ch3\u003eThe process\u003c\/h3\u003e\n\u003cp\u003eWater enters the tank and travels through a maintained pocket of air, where dissolved iron oxidizes into filterable particles. The media bed captures them, and the Control-Flow valve automatically backwashes the bed and restores the air pocket on schedule. There is no salt, no chemical feed, and no cartridge to replace — the system regenerates itself.\u003c\/p\u003e\n\u003ch3\u003eWhy the Control-Flow platform matters\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReliable, repeatable cycling\u003c\/strong\u003e from a purpose-built control valve.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProgrammable backwash\u003c\/strong\u003e so the system stays matched to your water and usage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eServiceable design\u003c\/strong\u003e with field-replaceable parts that keep long-term ownership straightforward.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhole-house protection\u003c\/strong\u003e against the rust stains that damage fixtures and laundry.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis system targets iron specifically.
