C-Series Blue-Green Copper Stains Filter

The C-Series system that solves it

This is a full C-Series system built on three parts that work together: a C-Series backwashing control valve on top of an upflow calcite tank, filled with the media matched to your water. The valve backwashes the bed on schedule to keep flow strong and the media working — no cartridges to change. One consistent C-Series platform means parts and service stay simple for the life of the system — fully serviceable, never a sealed throwaway unit.

What it does for your home

• Removes blue-green copper stains from your water
• Stops blue-green staining and pinhole pipe leaks
• Protects copper pipe, solder and fixtures
• Brings pH into a safe, non-corrosive range
• Self-backwashing calcite bed
