How Do I Install A Carbon Backwash Filter and a Water Softener In Series?
How to Install a Carbon Backwash Filter with a Water Softener
A common question we get is how to properly install an automatic backwashing carbon filter alongside a water softener. These carbon filters are designed to remove chlorine, tastes, odors, and sediment—while also being self-cleaning.
Installing a carbon backwash filter before the water softener is a smart move. It helps protect and extend the life of your softener by removing chlorine and other contaminants before they reach the softener while also improving water quality throughout your home.
Our 7500 Series Carbon Backwash Filters come equipped with a user-friendly control valve and a built-in bypass valve, allowing you to isolate the system for maintenance or service. To connect the carbon filter to your water softener, simply run a short length of PVC, stainless steel flex line, or PEX piping from the outlet of the carbon filter to the inlet of the water softener.
Together, these systems make an excellent combination for whole-house filtration and softened water.
