Introduction
The Watts OneFlow
system provides protection from scale
®
formation throughout the plumbing system. The OneFlow
system can be installed at the point of entry to treat your
entire system, both hot and cold water, or it can be located
directly before a water heater or other device (e.g. steamer,
etc) that requires protection from hard water.
OneFlow
reduces or eliminates scale formation on internal
®
plumbing surfaces as well as reducing spotting and streak-
ing normally associated with hard water.
OneFlow
prevents scale by transforming the normal dis-
®
solved hardness minerals into undissolved crystal micro-par-
ticles. 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 – Low or phosphate-free
®
cleaning products are recommended to achieve optimum
results. Modern surfactant or detergent based, liquid soaps
are preferred over old-fashioned caustic solid soaps.
Unlike softened water, OneFlow
the beneficial essential mineral content of your water and is
safe to drink.
