The 1.5-inch composite valve on this system is built to move more water while still giving each contaminant the contact time it needs.\u003c\/p\u003e\n\u003ch3\u003eAir injection at higher flow\u003c\/h3\u003e\n\u003cp\u003eThe treatment works the same proven way as smaller air-injection units — water passes through a maintained air pocket that oxidizes the dissolved contaminants, and the media bed filters out the particles — but the larger valve supports the greater service flow that big households require. The valve automatically backwashes the bed and restores the air pocket, so the system keeps itself clean and effective.\u003c\/p\u003e\n\u003ch3\u003eWhere it fits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarger homes and high-demand plumbing\u003c\/strong\u003e that would starve a smaller valve.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion-resistant composite control\u003c\/strong\u003e for long service life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChemical-free, self-renewing\u003c\/strong\u003e iron, manganese, and sulfur removal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProgrammable backwash\u003c\/strong\u003e matched to your usage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eHigh-flow systems must be sized to your actual peak demand and water chemistry to perform well.
