Anyone out there use this system? I talked to the Filter Guys today and this system wastes only 1/4 gallon water per each gallon made. This is so much better than wasting 4 gallons to make 1. The catch is, you need to have at least 65lbs of water pressure to run it, or buy a booster pump at a pretty good price. I'm trying to find a way to check my water pressure first, but I would to hear if anyone runs this system and could give me their opinion on it.
