The second stage filter includes an extruded carbon block filter to control chlorine, taste, and odor.

This second stage filter also utilizes Siliphos scale inhibitor, a unique blend of polyphosphate and sodium silicate, to remove dirt, rust, silt, and scale that can clog solenoids and orifices.

Polyphosphates bind with hard minerals, preventing them from attaching to metal surfaces, and sodium silicates provide a microscopic coating on metal surfaces, protecting them from scale and corrosion.

Inlet ball valve connections are 3/8"
compression fittings for 3/8" OD tubing.

Minimum 45 psi, maximum 100 psi feed water pressure.
