Due to fluctuating city water additives and noticeable adverse fish affects, i have decided that I am going to install an RO/DI unit in my home to support my tanks. But I am not sure how to go about integrating this into my homes plumbing system. I don't have a basement utility sink that i can just put a splitter on. I am thinking about mounting it under the kitchen sink and tapping into the water supply there, or maybe even putting a splitter on the cold water outlet that feeds my washing machine. From there I'll have it go into a tub with an auto-off float system.

Does anyone have experience with this? There should be a sticky in the DIY links post. What plumbing supplies would I need? Should I hire a professional plumber? I live in a new house with pvc throughout.

EDIT: After further searching, I found this article. Its a great place to check out: http://www.melevsreef.com/rodi_install.html

wish you would have posted this before you bought this 25gpd is not a lot of water that translates to 1g+/- usually less per hr. there is only a few dollars difference between that and a 100gpd unit. if you are going to use it in the three tanks in you sig. it will be frustrating to say the least.

I started with the ge ro unit that I got from home depot that was a mistake though I worked with it till the filters need to be changed it turned out to be a 10gpd that I was able to get 18 g out running it 24hrs a day.

if you can return it I would and get the larger out put.

hope this helps

Don't worry, i haven't bought anything yet. Just doing the preliminary research first. Not sure what sets one filter apart from another. 3 stage, 5 stage, $150, $400 dollars. Whats what?
 
I bought a kit a few years ago like the type you are looking at. The one I got was designed to go under the kitchen sink and has a small storage tank. What I found was the hoses and such that came with the kit made it easy for me to put the 3 gallon storage tank in that corner kitchen cabinet where you can never reach to get the things out of anyway. It ate up that unused corner. The faucet they gave me to put on top of the sink fit right into the hole where I once had a soap dispenser. The gallon tank actrually only holds a little over 2 gallons, the tank uses air pressure to move the water back out of the faucet so as it fills up the pressure in the tank goes up and about 2 gallons of water results in the fill stopping. The rest of the space in the tank is full of air. As has already been said, get a biger RO than you expect to need. RO ratings are based on warm water supplies at the correct pressure with no pressure at all on the tank. You will reduce flow by having cold water in the winter months, something other than ideal supply pressure and of course you will want the water tank to fill so the pressure on the outlet will go up. I can get about 18 gallons per day out of my 25 in mid summer. Any other time its less.
