About ten days ago I decided to replace my 10 year old Culligan reverse
osmosis system (that costs $20/mo and is close to 10 years old now)with
something modern hopefully better and cheaper. My only issues with the
current system are the monthly charges and water flow rates a bit less
than I would like. After 10 days of surfing, googling, reading ebay ads
and other web sites I am almost ready to buy.

Have you looked at http://www.waterfiltersonline.com/ ( I'm not
affiliated etc,etc,blah blah) I have been slowly replacing my GE r/o
system with parts from there.
Another thing that permeate pumps do is make the shutoff work on low
pressure domestic wells. If your well pressure tank only gets to 50-60
at the top end then the r/o will constantly run.
