        Stage 3 - EvenFlow Bed. Innovatively designed to maximize water treatment by substantially increasing contact time with the water filtration media.

          Why use an RKIN water softener

          Make it a combo with salt-free or salt-based water softener

          Why Use a Water Conditioner

          The mineral build-up, or scale, can occur in plumbing and household appliances when your water is hard. Solid deposits of calcium carbonate can form when hard water is heated. This scale can reduce the life of appliances, raise the cost of heating your water and clog pipes. Long-term movement of hard water through a pipe results in scale buildup. This can gradually close up the pipe and lower your water pressure.
