Just got an RO/DI unit on Ebay from Aqua-Safe Solutions. The problem is that I'm making more pure water than waste water. Is this possible? How does the membrane channel the waste water vs. the pure water. Did I install the membrane incorrectly? Scratching my head here.

Are you sure all the lines are connected correctly? Getting that much pure water is unusual even with optimum temp and pressure. I can't remember if the membrane has to go in a certain way or not, but I would certainly check that as well. Do you have a pressure gauge on the system?
I don't have a pressure gauge on the system, but believe that my pressure is fine. I checked all of the lines and they are hooked up correctly. I'm using a faucet adapter for this setup and running it directly from the faucet. At what pressure should I turn on the water?
lol...my next purchase. Used all my coin on the unit. For the most part in the beginning i was going to assume that i was getting decent water with a 6 stage unit as long as my water waste was either 3:1 or 4:1. Unfortunately, since I'm at 1:1 I have no warm fuzzy. Is there anywhere to get a TDS meter locally? Or will I have to order online and wait?
it looks like i got it working.....i had the membrane in backwards i think. (For some reason I couldn't get it in that way the first time so figured it was wrong). The instructions were less than clear. Right now I'm getting about 5 parts waste water to 1 part pure. This sounds about right with my crap tap water. I'll get a tds meter to verify the solids. Thanks everyone for your help!
