ro water system need help

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...
