Our largest whole-home system. A 96,000-grain softening tank and a separate carbon filter tank run from one control valve, built for big homes, heavy water use, and heavily treated city water.
Instead of putting resin and carbon in one tank, this system gives each its own. The softening tank removes the hardness minerals that cause scale. The carbon tank filters chlorine and chloramine, and it cleans itself by backwashing so flow stays strong. One control valve manages both.
Ion exchange removes calcium and magnesium from every gallon, so glassware, fixtures, water heaters, and appliances stay cleaner.
A dedicated coconut shell carbon tank reduces the disinfectants that give city water its taste and smell.
A 27 GPM service flow keeps up with large homes, several bathrooms running at once, pools, and continuous use.
The carbon bed backwashes automatically to keep water flowing evenly and extend its life.
Demand-initiated metering regenerates the softener based on actual water use, rather than a fixed schedule.
Plus coverage on the valve and electronics, and a labor warranty on the install.
Three vessels work together.
High-capacity cation resin removes the calcium and magnesium that cause hard water.
Granular activated coconut shell carbon over polishing gravel reduces chlorine, chloramine, and taste and odor compounds.
A 15" × 35" square salt tank supplies the brine used to recharge the resin.
For many homes our standard softener and filtration system is plenty. The dual-tank system is the better fit for larger homes, high water use, pools or continuous demand, and heavily chlorinated city water. We size it to your house when we quote.
