Specifications
A OneFlow scale prevention system shall be installed on the main
®
water service pipe just after it enters the building, but after other
whole building water safety devices (backflow preventers or pres-
sure reducing valves), to effectively address water hardness con-
cerns. A system may also be installed further downstream to protect
specific equipment or areas within a plumbing system. The system
shall be plumbed with a bypass valve to allow isolation of tank(s)
and to allow the bypass of untreated water in the event that service
or media replacement be necessary. The installation area should be
suitable in size for the tank(s) to be serviced without encumbrance
and sit upright on a flat level surface.
The system must operate in an upflow manner and does not require
additional water to backwash, flush, or regenerate once put into ser-
vice. The system does not require any chemical additives and does
not require electricity for operation.
Multi-tank systems shall be installed in parallel with PVC/CPVC man-
ifold to meet peak flow rate requirements – see image below.
Standards
Independent scientific testing has confirmed Template Assisted
Crystallization (TAC) technology provides scale reduction of over
95+%. Testing was conducted under protocol based on DVGW
W512 test to access control of scale formation.

NOTICE
Important notice about iron, manganese and copper in the
water supply.
Iron and Manganese
Just as with conventional water softening media, OneFlow
to be protected from excess levels of certain metals that can easily
coat the active surface, reducing its effectiveness over time. Public
water supplies rarely, if ever, present a problem, but if the water
supply is from a private well, confirm that the levels of iron (Fe) and
manganese (Mn) are less than 0.3 mg/L and 0.05 mg/L respectively.
Copper
Pursuant to the EPA drinking water standards, the copper concen-
tration permitted is up to 1.3 ppm. Typically originating from new
copper plumbing, high levels of copper can foul OneFlow media.
For applications with copper concentration greater than 1.3 ppm,
please consult Watts Water Quality Technical Service. To further
minimize any problem with excess copper, avoid applying excessive
flux on the inner surfaces of the pipe and use a low-corrosivity water
soluble flux listed under the ASTM B813 standard.

CAUTION
!
• Not for use on closed loop systems.
• Do not let the system freeze. Damage to the tank may result.
• System must be operated in a vertical position. Do not lay it
down during operation. The system may be placed in any posi-
tion for shipping and installation but must be operated in the
vertical position.
• Place the system on a smooth, level surface. Because the system
operates in an upflow, fluidized bed mode, having a level surface is
more important than with a softener or media filter.
• A bypass valve should be installed on every system to facilitate
installation and service.
• Observe all local plumbing and building codes when installing
the system.
WARNING
!
Using OneFlow with other water treatment
®
equipment.
Due to the unique properties of OneFlow
requirements for using OneFlow
other forms of water treatment.
1. OneFlow must be the last stage in the treatment chain.
®
Do not install any filters after OneFlow
which scale prevention is required. POU filters, e.g. carbon, RO
or Ultraviolet (UV) are exempt from this requirement.
2. Do not apply phosphate or any other antiscalant before or after
OneFlow .
®
3. The addition of soaps, chemicals, or cleaners, before or after
OneFlow treatment, may reverse its anti-scale treatment effects
and/or create water with a heavy residue or spotting potential.
Any adverse conditions caused by the addition of soaps, chemi-
cals, or cleaners are the sole responsibility of the end user.
4. OneFlow is not a water softener and does not softener the
water - Water treatment chemistry (e.g. antiscalants, seques-
trants, soaps, chemicals or cleaners etc...) will most likely have
to be changed to be compatible with OneFlow treated water.
Laundry and ware-washing chemistry will likewise require
adjustments.
NOTICE
Spotting May Occur on External
Plumbing Surfaces
OneFlow media systems perform best in single pass potable water
applications with NO additional chemical additives. Depending on
hardness, soft scale spotting may occur. Soft scale spots in most
cases can be easily wiped down with a damp cloth and will not form
hard scale deposits. A Point of Use (POU) Water Softener should
be used on mandatory spot-free applications (e.g. glass stemware,
dishware).
