Whole House Iron, Hydrogen Sulfide, and Manganese Reduction Systems

Series PWBWIRON systems are selected for use when the concentration of iron, manganese, and hydrogen sulfide in water need to be reduced. They use the model 2510 AIO Control Valve to reduce the contaminants in the water without the use of chemicals. The 2510 AIO valve is specially designed to capture a volume of air inside the system's mineral tank. Water passes through the AIO valve, then passes through the air head in the top of the mineral tank. Oxygen from the captured air transfers into the water. The oxygen oxidizes these contaminates in the water to oxides or solid precipitants. Then they are mechanically filtered out of the water by the Filox media filter bed. The Filox media removes any residual iron, manganese, and hydrogen sulfide that has not formed into a solid by catalyzing it quickly into an oxide. After a preprogrammed number of days has passed, the system will perform a regeneration cycle to clean the Filox media of the solids it has accumulated, draw in more air, rinse, then return to service. Watts recommends a daily regeneration of the system. Connection Size: 1 in. - 3 in. (25mm-80mm) Flow Rate: up to 18 gpm (23 lpm)


  • High flow rates with smaller system requirements than competing models
  • Reliable control valve features electronic controller for easy programming
  • Reduces red-staining iron, black-staining manganese, and unpleasant smelling hydrogen sulfide in water without use of chemicals
  • Catalytic filtration media is advanced form of manganese dioxide for maximum iron removal
