My wife was bothering me for a R.O. system for the house. After finding this company online I decided to go by their showroom to see what they had. The gentleman working there asked me various questions to determine my needs. After deciding on a 5 stage R.O. system he packaged it up for me and told me to call him if I had any problems installing it. I am very handy and installed it correctly but there was a problem because the water pressure in my area was too high. I got a regulator from him and now it works perfectly. Clean drinking water with no funny aftertaste like tap water. My wife loves it.
