During the design phase of our home, it was important to us to find a whole house water treatment system. Greg, recommended a water softener and carbon filtration system that would soften and filter the water supply to the entire house and guest house. Today, we enjoy softened/filtered water from every faucet and shower head. No more hard water rings in the toilets or hard water build up on our faucets or shower heads. And, no additional separate faucets for “drinking” water. We Love It! Johnson water gave us great guidance and service.
