1400 gallons isnt bad - if you arent flushing before you restart your ro then you are pushing 100+ TDS through the DI resin and exhausting it quicker. everytime you restart your RO have the water from the ro membrame (before the resin) empty into a bucket for 5 minutes. this will flush the membrane. just for chits and giggles check the tds of that water
