WATER SOFTENERS
Select smaller water softening systems sized to handle no more than the service flow rate rather than larger tanks with less frequent regeneration or tanks on standby for extended periods of time. Select multiple tanks for systems with wide flow variations. Supply fixture unit tables based on Hunter’s curves are not corrected for water conserving fixtures and their use commonly results in oversizing. SPS 382.40(7) accepts and DFD recommends sizing based on a detailed engineering analysis to avoid oversizing of equipment. Reference Water Quality Association studies (Aquacraft 2001 single family residence, IAPMO/WQA/ASPE 2016 residential study by Univ. of Cincinnati). Idle conditions contribute to microbiologically induced corrosion and associated water quality concerns.

Maintain water softeners in dry bypass mode until active use. Program and cycle water softeners for specified minimum efficiency rating, regeneration cycle intervals and times, consumption, backflow rate, brine flow rate, variable reserve and proportional brining, etc. Program standby ion exchange media tanks into service every 12 hours for minimum of 1 tank full of water to pass through. Provide initial salt fill of brine tank. Test and report on untreated and treated water hardness, pH, iron and chlorine. For water softeners demonstrating efficiency through field sampling, meter analysis and adjustment; report field data confirming efficiency.
