I have not ever felt a need for more stages than this. I flush my membrane religiously each time and only allow water to enter the resin when it's 3 TDS or less. Filters and resin last me a long time. |
lastlight has the right idea here... make sure you have a tds meter to measure the water after the membrane AND after the DI resin stage. If the unit hasn't been running for a bit then flush till the TDS is in the single digits after the membrane... ususally takes about 1-2 minutes. You'll save HUNDREDS of dollars on filters and resin (over the life of your unit) if you take this precaution.
