Can you help me understand the realities of using these systems with hard well water? It's a very big deal to me to dump 4 gallons of waste water to get one of purified. Are these real world numbers?

I'm not Ray, but I can help answer this. Some RO systems do waste alot of water, some more then others. You can "catch" the waste water in a barrel, and refilter until your ppm level reaches the maximum allowed/suggested by the RO manufacturer. To get the "catch" water back thru the RO system you will need a sureflow diaphram pump. What is the ppm of the well water before filtration? Softening may not be necessary if under the maximum suggested by manufacturer.
