10gReef Posted February 10, 2014 Share Posted February 10, 2014 I keep seeing mentions of the waste water from ro/di filters. I used to dump one line off my filter but decided to plumb it in. I have been making water this way for about a year and have seen no ill effects. I am curious now as to which line coming out is the waste.

bige Posted February 10, 2014 Share Posted February 10, 2014 I think the problem with this is you would burn through your filters. Have you tested your Tds? How often are you change your filters? Quote Link to comment Share on other sites More sharing options...
Sascha D. Posted February 10, 2014 Share Posted February 10, 2014 "Waste Water" is used to reference the drain line. What did you plumb it to? I know you're not supposed to drink the water from our filters because of the bacteria. Most are labeled not suitable for drinking water.

ceastman Posted February 10, 2014 Share Posted February 10, 2014 The line coming out of the flow restrictor should be the waste water line. Quote Link to comment Share on other sites More sharing options...
madsalt Posted February 10, 2014 Share Posted February 10, 2014 I'm not too familiar with that unit but I would say the line coming off your resin filter would be your waste water line. You could always look up the manufacturer and I am sure they would have a diagram. Quote Link to comment Share on other sites More sharing options...
victoly Posted February 10, 2014 Share Posted February 10, 2014 Are you talking about plumbing your waste line back into your infuent (tap) water? Quote Link to comment Share on other sites More sharing options...
10gReef Posted February 10, 2014 Author Share Posted February 10, 2014 I plumbed it in to same line that I fill my water jugs with. I'm not dumping any water but using all of it to make salt water Sent from my Nexus 5 using Tapatalk Quote Link to comment Share on other sites More sharing options...
victoly Posted February 10, 2014 Share Posted February 10, 2014 There's no point to running rodi then. You're removing some particulates and VOCs/chloramine with the carbon, but everything else is going back in that would normally be taken out.

Like Victoly said, all of the stuff that doesn't get stuck in the filters goes out through the drain line. If the drain line is going into your jugs, then you're not really removing anything except cash from your wallet. Quote Link to comment Share on other sites More sharing options...
jestep Posted February 10, 2014 Share Posted February 10, 2014 It should work fine for watering plants or a lawn or washing clothes. Quote Link to comment Share on other sites More sharing options...
Planeden Posted February 10, 2014 Share Posted February 10, 2014 on the bright side, you've been using tap water for at least a year...you may not need RODI and can just sell off the unit . oh, and buy dechlorinator. 2 Quote Link to comment Share on other sites More sharing options...
Bpb Posted February 26, 2014 Share Posted February 26, 2014 True that. What you're doing is the same as just using a dechlorinator in your tap water. However...has anyone plumbed their waste line back into the intake? Should have pretty similar tds to the original tap right? Seems it would be efficient use of waste. How exactly would it burn through filters faster? Quote Link to comment Share on other sites More sharing options...
Timfish Posted February 26, 2014 Share Posted February 26, 2014 An RO membrane is just a fancy super effeceint mechanical filter and it will clog over time. Plumbing the waste back into the intake will clog it faster as the larger particles and molecules are not being flushed out and get trapped in the membrane. As Victoly pointed out the waste will be somewhat cleaner than the intake as the carbon and prefilter removes some stuff. Quote Link to comment Share on other sites More sharing options...
