Introduction
The Watts OneFlow Anti-Scale System provides protection
®
from scale formation on internal plumbing surfaces. The One-
Flow system 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
®
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 or a chemical additive (like
®
anti-scalants or sequestrants). It is a scale prevention device with
proven third party laboratory test data and years of successful
residential and commercial installation. OneFlow® is the one wa-
ter treatment device that effectively provides scale protection and
is a great salt-free alternative to water softening (ion exchange) or
scale sequestering chemicals. Laundry and warewashing chemis-
try will likewise require adjustments.
OneFlow Benefits
®
• Chemical-free scale prevention and protection – converts
hardness minerals to harmless, inactive microscopic crystals
making OneFlow an effective alternative technology to a
®
water softener for the prevention of scale due to water hard-
ness
• Virtually maintenance free - no control valve
• Uses environmentally friendly technology by using no salt
or other chemicals to constantly add, no electricity and no
wastewater
• Improves efficiency of all water using appliances – both hot**
and cold
• Simple sizing & installation – all you need to know is pipe
size and the peak flow rate.

Model OF1054-20
• Safe for landscaping and lawn watering. No need for costly
bypass plumbing.
• Compatible with all on-site and community wastewater treat-
ment systems.
• Perfect system for towns or communities where water soften-
ers are banned or restricted
• OneFlow does not remove minerals or add sodium to the
®
water supply
• OneFlow can be installed as pre-treatment to commercial
reverse osmosis systems (contact your Watts Representative
for further details)
* For high-flow applications, contact your Watts Representative
for details on larger, multi-tank systems plumbed in parallel
that can meet high flow applications from 100 gpm to and
above 1000 gpm
** For hot water applications where feed water temperature is
100°F – 140°F (38° – 60°C), please consult ES-OneFlow-
HotWater.
Systems are certified through WQA
against NSF/ANSI Standards 61 and 372
for Lead Free compliance.
! WARNING
Do not use with water that is microbiologically unsafe or of
unknown quality without adequate disinfection before or after the
system.
