How the EC4 Water Conditioner Works

Step 1:

Water enters RainSoft's exclusive rugged control valve and flows down through the EC4 resin tank.


Step 2:

The water is filtered and treated as it passes through the special "ion exchange" resin. Hardness ions are ionic ally retained in and on the resin. The optional carbon bed further polishes and clarifies the water.


Step 3:

Once completely conditioned, the water exits the resin tank through the riser pipe and out the control valve.


Step 4:

At metered intervals, the unit begins a regeneration process. Using salt as a regenerant, the retained hardness ions are flushed out of the system and down the drain. The unit then prepares itself for the next conditioning cycle.*
