How long should your working capacity last?
Start with documented capacity, separate reserve, water use and hardness. Compare the calculated interval with your actual cycle record.
Calculate a regeneration interval →What these tools can tell you
The capacity calculator gives you a working-capacity target to discuss with a supplier. The running-cost calculator adds up the operating expenses you enter. The regeneration tool estimates an interval from available capacity and daily load. None selects a particular model or predicts your controller’s actual schedule.
Keep your inputs useful
Use information from your own water test, model manual, and bills. The example inputs demonstrate arithmetic; they are not measured averages or recommended settings. Your results can be printed, and calculator entries are not sent to a server.
