Just as with conventional water softening media, AquaSolve Anti-Scale media needs 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.

Pursuant to the EPA drinking water standards, the copper concentration permitted is up to 1.3
ppm. Typically originating from new copper plumbing, high levels of copper can foul
AquaSolve Anti-Scale media. For appli-cations 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.

AquaSolve Anti-Scale media does not reduce silica scaling. While silica tends to have a less
significant effect on scale formation than other minerals, it can act as a binder that makes
water spots and scale residue outside the plumbing system difficult to remove. This 20 ppm
limitation is for aesthetic purposes.

All other contaminants must meet the requirements of the USEPA Safe Drinking Water Act.
Specific Mineral and Metal MCL’s, identified in Watts published Feed Water Chemistry
Requirements, supersedes the USEPA SDWA.
NOTE:
Systems using AquaSolve Anti-Scale technology prevent scale formation inside the
plumbing system at influent hardness levels of 30 grains per gallon of calcium carbonate and
less. Due to variances in water chemistry, certain aesthetic conditions external of the plumbing
system may not be attained. AquaSolve Anti-Scale is designed for the treatment of potable
water that meets the requirements of the current USEPA Safe Drinking Water Act.
