NWS 1.5" composite-control air-injection system
This is a higher-capacity air-injection system built on a 1.5-inch composite Nelsen Water Solutions control valve — sized for larger homes and higher-demand wells that need strong flow while removing iron, manganese, and sulfur odor without chemicals.
Why bigger plumbing needs a bigger valve
Homes with many bathrooms, high simultaneous demand, or larger service lines can outrun a small control valve, causing pressure drop and letting water pass too quickly for complete treatment. 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.
Air injection at higher flow
The 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.
Where it fits
- Larger homes and high-demand plumbing that would starve a smaller valve.
- Corrosion-resistant composite control for long service life.
- Chemical-free, self-renewing iron, manganese, and sulfur removal.
- Programmable backwash matched to your usage.
High-flow systems must be sized to your actual peak demand and water chemistry to perform well. The system installs on the main line with a backwash drain. Send us your water test and flow requirements and we will confirm this is the right capacity for your home. Ships free in the US with manuals and expert sizing support.
Right-sized for big demand
For a large home, capacity and flow have to be matched to the plumbing so the system never becomes a bottleneck. Share your number of bathrooms, peak simultaneous use, and water test, and we will confirm the 1.5-inch platform is the right fit, set it up for your conditions, and back it with expert US support.
Backed by free US shipping, complete manuals, and hands-on sizing help, this high-capacity platform keeps a busy household in strong, well-treated water without the pressure drop a smaller valve would cause.
