http://www.thefilterguys.biz/ I called them up, told them what I wanted to do, they sent me everything I needed. Very simple. They set me up with a 3 stage filter, and a 40 GPD "regulator". The regulator is a small plastic tube that connects inline to the output line out of the filter assembly. Not much to it, really. I guess it maintains a certain pressure, and knowing the ID of the tubing, that pressure means that water has to flow out of the tube at a certain rate.
I'm interested in the auto water changer. Where did you get the regulators and how do they work. Sorry if I missed it.
