How do i add DI to my existing RO unit this one https://www.nilocg.com/shop/600-gpd...ng-water-filtration-system-with-booster-pump/ i have the tap water line coming from the faucet in the basement to the unit, and then pure water to the tank, and then waste water. My lfs said he have the attachment to make it DI. but how do you attach DI to this unit? does the pure water line goes to the DI, and then to the tank?
