I was having stomach problems and diarrhea regularly before I began to use the purified water.  I have noticed a remarkable difference since using pure water.  My blood pressure is back to normal and no more diarrhea.  Over the past 2 years since the filtration equipment was installed I have reduced my medication.  The cost of medication and the health benefits I have received have made the equipment very worthwhile.  I don't have the scaling deposits I had before and the RO water tastes great.  No other filtration equipment will remove the contamination and hardness in the water like this system does.  I am also amazed at how little salt the refiner uses.  The crap in my water, I believe, was the cause of my illness, I feel like a new man now.  I've had my water tested before by others and I had no idea what the results meant until Robert explained everything to me, now I know.  I would recommend these systems to everyone interested.
