Introduction
The Watts OneFlow
Anti-Scale System provides protection from
®
scale formation on internal and external plumbing surfaces. The
OneFlow
system can be installed at the point of entry to a build-
®
ing to treat both hot and cold water, or it can be located directly
before a water heater, boiler, or other water using device that
requires protection from hard water.
OneFlow
prevents scale by transforming the normal dissolved
®
hardness minerals into undissolved crystal microparticles. These
crystals stay suspended in the water and have a greatly reduced
ability to react and attach to surfaces like dissolved hardness
does. Therefore the problem of internal buildup of scale in pipes,
water heaters and on fixtures and glass is greatly reduced.
OneFlow
is not a water softener – Water treatment chemistry (e.g.
®
antiscalants, sequestrants, etc.. will most likely have to be changed
to be compatible with OneFlow
washing chemistry will likewise require adjustments.
