Just thought I would chime in here. I'm just curious why neither of you bought the storage tank for the RO System. Most RO systems have an automatic shutoff when the tank is full so you don't ever have to worry about it. There is a complete set-up for under your kitchen sink for just under $150 (and free shipping). This particular one is a 5 stage 50GPD system that is quite easy to install. Here is the link for the one I purchased which includes a 2.8 gal storage tank and the faucet for the kitchen sink. http://www.affordablewater.us/5-Stag...Yn1S6jmipDalaW
I use 15 to 20 gallons per day for my collection and this system has been working great for me for a year and a half now. I have extremely hard water here in southern California...about 550 to 700ppm and this RO System brings it down to 10ppm.
Below is a typical setup for an under-the-sink system and looks just like mine.
Here are a few pics of my installation in my kitchen. The hardest part of the install was drilling the whole in the stainless steel sink.
The RO faucet is the one on the left and its pressurized just like your other faucets in the house. It comes out very fast until the tank is empty (2.8 gals) and then just stops until it purifies more water.
All nice and neat so there are never any visible filters or hoses (or timers) to worry about. All you have to do is fill jugs and store them.
