These systems are designed to treat the domestic water used in asingle family dwelling. For irrigation water treatment or higher volume applications please contact your Watts representative. Peak service flow rates are based on a 15 psi drop.Optimum service flow rate is specific to water chemistry and will vary.PWFMZ SeriesPWFGAC SeriesPWFCAL Series
