How Does it Work?

OneFlow^® is the environmentally-friendly way to prevent scale buildup. Through Template-Assisted Crystallization (TAC), dissolved hardness minerals in the water join together, forming microscopic crystals on the surface of the OneFlow media. Once formed, these crystals detach from the media and flow freely through the plumbing system, unable to form hard scale on internal plumbing surfaces.

OneFlow maintains...

Without scale buildup on the heat exchanger, your water heater can efficiently transfer energy to the water, keeping energy bills in check.

Make scrubbing and polishing a thing of the past. Soap and shampoo residue rinses off quickly and more easily than with untreated water.
