duff co water treatment flow rates using fixture counts before recommending a softener it is important to determine soft water service flow requirements and volume in a given time period water meters are the best source for such data where meters are not used flow rates and total requirements may be estimated using the basic information after determining this information a properly sized softening unit may be recommended use fixture unit table and intermittent flow rate table for average and maximum flow rates in private and public buildings in gallons per minute the unit flow rates are to be used when actual continuous and peak flow rates are not known the average rates may bed used when line pressure less the conditioner pressure drop is at least 30 psi at the highest point of use in the building [approximately 4 psi loss per story the maximum rates are equal to the fixture count figures commonly sued to size drains and are applicable especially in low water pressure areas where pre
