Using OneFlow ® with other water treatment
equipment.
Due to the unique properties of OneFlow ® , there are some
unique requirements for using OneFlow ® in conjunction with filtra-
tion or other forms of water treatment.
1. OneFlow
® must be the last stage in the treatment chain. Do
not install any filters after OneFlow ® or before any devices for
which scale prevention is required.
2. Do not apply phosphate or any other antiscalant before or
after OneFlow ® .

Note: Peak service flow rate is for intermittent use only and is
not to be interpreted as continuous service flow rate capability.
These systems are designed to treat the domestic water used
in a single family dwelling. For higher volume applications please
contact your Watts representative.
