How Do I Install A Carbon Backwash Filter and a Water Softener In Series?

A common question we often get is how to install an auto-backwash carbon filter and a water softener.  Carbon filters remove chlorine,  tastes, odors and sediment and are self cleaning.   Carbon backwash filters installed in front of water softeners or no-salt water conditioners make a great combination.

The carbon filter is installed prior to the water softener.  This extends the life of the softener by removing chlorine prior to the softener and makes for great clean water through out the home.

7000-SXT systems come with bypasses, so you can bypass each system individually as needed.  You can simply connect the output of the carbon filter to the input of the softener, either by using a short length of PVC, a stainless steel flex line, PEX piping.
