Hint. If it doesn't have a shut off set the kitchen timer to when you think your container will be full. It might save you from waking in the morning to a flood.

Agreed! I have super close a few times now to having a serious flood, but caught it just in time.

That thing looks pretty well used...any idea how old it is? Or how well used the membrane and other filters are in it? Looks like its probably a good unit,but if you have to purchase a new membrane and all new filters...that money you thought you had saved buying used is long gone.

I will have to get my unit out and look at it to be able to tell you which housing is for what and what the path of the water should be is...

You'll need those for the pre-filter chambers. You'll probably need to change the RO membrane as well, use a Filmtec 75 GPD as they are the most efficient membranes.

For the container use a Rubbermaid 32 gallon trashcan, works perfectly.

You don't need the filters on the left, use the unit on the right. Understand that the water goes through the three pre-filters and then enters the RO chamber through a single inlet and exits the chamber in two outlets. One is the drain line (the shorter outlet from the inlet) and the other (the longer outlet - usually the bottom) is the purified water.

You're also going to need a flow restrictor on the drain line, possibly an auto-shut off kit (to automate the filling process) and maybe a pressure gauge.

Just in case you're a bit intimidated by what all this stuff is (like I was before I got an RO/DI unit, this

is the kind of gear mentioned there. The float valve (the one on the top) gets mounted on the upper end of the side of the Rubbermaid kind of resevoir that Raul recommends and it will prevent the water from filling up beyond where it's mounted when used with the auto-shutoff.

http://www.thefilterguys.biz/ thats who i bought my unit from. I was looking at used systems on ebay and i ended up calling them about a specific part i needed. He spent about 20 minutes on the phone with me (even though he was in the middle of a computer crisis) explaining to me what i needed and why. He did mention at the very beginning that generally he thought people were better off buying new, and i kinda just brushed that off at the time. He still spent considerable time helping me, knowing full well i may not even spend money at his store. With in 10 minutes of hanging up the phone i decided to order a new unit from them. Thats customer service that cant be beat! There are a couple of guys on here like that too..Orlando and Momotoro being 2 of them.

But anyway, my advice is check them out. I have never used or even checked out the website that Raul-7 posted, they might be very good also. Price isnt always the ONLY issue for me though, especially when im going to need considerable hand holding along the way! haha And i found the filter guys prices to be as good or better than the vast majority of what was available out there, except a couple of the ebay mega store type places.

The two filters on the left of your pic would be for DI resin, which Raul-7 is probably right about...you probably dont need it. Its just the last step in the purification process, and it takes it from being something like 95 to 97% pure up to 99. something % pure. Not necessarily needed for what we're doing, but if you already have it it may be worth using, depending on what it will cost to use. Kind of just have to do cost to benefit ratio determination on your own.

I use a large bin that is used for storing wrapping paper tubes to collect my water. It just happened to be the perfect size for where i wanted to store my tank. But more or less the same type of idea as a rubber made garbage can....but much cheaper! It holds about 15 gallons, which is the perfect amount for water changes for me.

The pressure guage would be for knowing when you needed to replace the micron filters or membrane. You start at a certain pressure when new, and then as things start to get clogged up and worn the pressure increases, telling you its time to change. Can be nice to have, but its definitely not a must.

I dont think you HAVE to have a flow regulator on your drain line, it just depends on what else you have on your unit. There are a ton of different things you can add on to your RO unit to make it work better or just be extra fancy if thats what your in to. The only extra thing i added on mine was a bypass valve so i could flush out the membrane after each use to extend its life. No other bells and whistles at all, and im doing fine with it. The automatic shut off is something i DEFINITELY would like though, its a cheap and easy thing, especially compared to a flood! lol I just havent pulled the trigger on it yet, probably because i like to learn things the hard way???

But again, i would spend some time talking someone knowledgeable about RO units to help you make some of these decisions....The Filter Guys get my vote with out hesitation...

I second The Filter Guys. He worked with me both through email and on the phone to figure out just what I needed. Once I got the filter I took tests through every stage to see if he was just selling me more than I needed but he was dead on.
