Twin Tank Water Softeners

Twin alternating water softeners offer a slight efficiency advantage over a single tank design. On a twin system, the softener switches tanks then immediately regenerates the tank it just took offline. This allows the system to run each tank all the way to full capacity before switchover. In a single tank system, you must have enough remaining capacity to make it through a full day of the water softener has to regenerate the night before. If you are using a water softener as pre-treatment for a reverse osmosis system a twin alternating model is online 24 hours a day and therefore eliminates the need for pre-treatment lockout on regeneration. For most residential applications we recommend a single tank system. On a residential application the 5%-7% salt savings only amounts to maybe $1.00 per month in actual cost savings.
