Acidic Water Neutralizing System
*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 irrigation water treatment or higher volume applications please contact your Watts represen-
tative. Peak service flow rates are based on a 15 psi drop.
Optimum service flow rate is specific to water chemistry and will vary.
