In short
The Confluence is the twin-tank water softener in the Three Rivers lineup, in three sizes: when one tank is exhausted it switches to the second, so treated water keeps flowing, even during regeneration. It is installed across the Greater Pittsburgh area for busy homes that need soft water around the clock.
