How/Where To Hook Up RO/DI Water Filter????

[NaH2Ofreak]

I got a new ro/di filter for christmas! Yeah!!!!!! A couple questions. If the minumum temperature of the incoming water is to be greater than 40 degrees, how could you hook it up to a garden hose or even a "cold water only" supply???? Isnt the temp of the incoming city water less than 40 degrees?????? Where do you have your filter hooked up? Please share!

Merry Christmas!!!!!
Thanks!

I have my RODI unit under my kitchen sink, hooked up directly to cold water line.

Mine is in the basement, right after the water line comes in from outside.

Here's how I did mine

saddle valve on cold water line into the water heater, the black waste line goes out the garage door into the yard

most important thig is to place it where you can access it for maintenance.. Mine is under my kitchen sink.. it's a bear to change filters

Ditto. I regularly get condensation from the unit, because the incoming water is so cold in the winter months. Dunno if that affects the quality of the product water or not (I don't think so, only the efficiency of the unit), but my fish haven't complained yet.

Hey MeGaDeath.. how far does that line go, to reach the outside of then house? I was toying w/ sending my waste water to my vegetable garden in the summer, but was concerned about back-pressure on the RO membrane?

Mac, it is important to have some back pressure in your waste water line. That is one of the basic principals of RO - the back pressure forces more water through the membrane - that is why there is a flow restrictor in the waste water line. If you want to run your hose outside, I would remove the flow restrictor (usually placed in the waste water line at the connection on the membrane housing). Then run your unit and measure the ratio of waste to product (should be at least 5:1) If you have more that 10 parts waste to 1 part product, then re-insert the flow restrictor and cut it down until you have between 5 and 10:1. The higher the ratio, the more water you will waste, but the longer your membrane will last since less solute will get driven into the membrane. Water temperature will not affect the quality of your product as far as I know - just the volume.

hi.
Temperature affect the quality of the RO as well as line pressure. If you want to use the waste water for your garden, just drain it into a container that is opened to the air, and you don't have to worry about playing around with the flow restrictor and stuffs. Unless your RO unit is 20 feet below the waste water container, or the drain line is partially blocked, or the container is a closed container, the back pressure on it is minimal, and of no concern.

Thanks for all the info! Im going with the garden hose adapter now. I may change it to something different later.

Thanks again!

I had used a garden hose adapter for the past three years. This really was a pain and my wife got fed up with having this unsightly contraption constantly in view on my pool deck.

I finally took the plunge and plumbed my RO/DI under my sink. I purchased a drinking water kit and now as an added bonus I have RO water to drink! I could kick myself for not doing this three years ago.

mitch :roll:

The RO/DI I have came with a valve to set the ratio, I tuned it after I had run the waste line into the yard.

I set it to 3:1 I thought that's what he told me on the phone (http://www.aquaticreefsystems.com/) maybe it was 4:1, I know it wasnt 5:1 that's a pretty bad ratio.

Hello guys and gals, I have been interested in the Ro/DI unit for a long time now. But have been afraid of the unsightlyness of the unit. Mabe some of you can help me be a little less afraid. I would like to know a little more about the unit under the sink. For instance, where do you put the filtered water? How do you put a tank under there to hold you water? Where do you run the waste water? Do you somehow run it into the drain line? Also was it easy to hook up the RO unit to the tap for drinking water mitchell? Where did you get the kit? And how does it look? How about some pics or easy to read instructions. Mabe the wife would go for getting one of these things if I could keep it out of sight and give her RO water to drink. Sorry so many ?'s but these have been on my mind for quit some time so be ready their may be more. Thanks, Doug.

I had the undercab setup at my last house, it had a 3g storage tank, and a faucet for it. It's really easy to install, the input line is a saddle tap on the cold water line to your sink. The waste line is a tap drilled & fitted to your sink drain. The faucet was really easy to install, just drill a hole in the sink top. I would do that again, but now my sump & all equipment is in the garage, cement slab flooring, so no crawlspace to route threw

Check out home depot for thier undercab setups, there's also a few places online that sell them really cheap, but hard to get a feeling unless you check out the display at home depot, ours has them out so you can see what it is & how big the parts are.

All you need to do then, is add another line & valve, from the storage tank out to wherever you need your reef water, feed that threw a DI canister and your set, a few places sell add on DI undercab filters, that's all you need. L8r mega
