Introduction
The Watts OneFlow
Anti-Scale System provides protection from
®
scale formation on internal plumbing surfaces. The OneFlow
can be installed at the point of entry to a building 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 hard-
®
ness 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
treated water. Laundry and warewashing
®
chemistry will likewise require adjustments.
OneFlow
