Watts 7100479 Automatic Iron Filter 1 Cu Ft 6 Gpm

Product Description

The WATTS 7100479 is an automatic iron filter designed to remove dissolved iron from residential water supplies. The unit holds 1 cubic foot of filter media and delivers a maximum flow rate of 6 gallons per minute (GPM) through a 1-inch female pipe thread (FPT) connection. Licensed plumbers and water treatment technicians install this filter as part of whole-home water conditioning systems where iron fouling causes staining, taste issues, or damage to fixtures and appliances. The automatic backwash cycle regenerates the media without manual intervention, keeping the system running with minimal maintenance.

This iron filter is suited for residential applications where iron concentration in well water or municipal supply causes recurring problems with plumbing fixtures, water heaters, and appliances. The 1-inch FPT inlet and outlet connections fit standard residential main-line plumbing. At 6 GPM, the unit supports typical single-family household demand without significant pressure drop during normal service flow. It is typically installed at the point of entry, upstream of water softeners or other treatment equipment.
