Do NOT believe a word these people try and pitch to you. If you are worried about your water quality, order a water text kit and perform simple tests yourself. The sales reps will lie lie lie and do whatever they can to get you to purchase their system. Scare tactics should not be a reason to purchase something without proper research. Our water quality is perfect and we were led to believe that its horrible and our family is in peril due to what we are drinking. Total crap. Test your water yourselves. Do NOT believe the smoke and mirrors these guys are selling.
