Hello,

I was wondering what you do with the water from water changes. Seems like a waste to dump down the drain.

I guess with winter coming, it can be used to melt snow on the driveway.

Thanks.

Don't put on driveway.
Does not work like you wish!

Also, not good for grass and flower beds against the driveway.

I figure since I need to pay for sewer waste whether I use it or not, might as well go down the drain.

The bigger question is, what do you do with waste water from the RODI system?

  • water for the dog dish
  • tried for laundry (don't do it)
  • watering plants
  • ????/

Sounds like there's a story associated to the laundry advice lol

Off topic, but don't START with me about A-Hole neighbors. Literally told me he has no pets or kids so no need for a fence. How much fun do you think I made it for him have a landscape company come between the houses with big machines? That's right. I told the company no way. He had to change to all small stones so a small machine could get them through, and job took twice as long. I did tell him one way or another he was going to pay! Jerk.

Back on track.

I've read somewhere about not drinking waste from RoDI, can't remember where. So I'd be worried about feeding it to my pets. I do through A LOT though, so if plants or any other ideas are out there, I'd be happy to listen.

Waste rodi is exactly that. Waste, it's a concentration of all the bad stuff stripped from the water and rinsed thru the waste, why would you want to think you could use that?

I reuse my rodi waste water. The waste water goes back to my cistern and gets reused. I have to shut off that hose in the winter of course cause the waste line freezes.

Think of the amount of water going back down the drain once it goes through the RODI system.
Even a good system is still 2:1 I believe. Booster pumps and all running well.
If drinking RO water is bad for you because all the good stuff is taken out, then drinking some RO waste should be fine (for animals!)
Not a full diet of waste only water but the odd fill up of their bucket I don't worry about.

Still listening for good uses of the waste!

Drinking ro water is fine, drinking rodi they say is not, drinking the waste is drinking a concentration of what you want to remove before you drink it?? [emoji848]

I would never give or offer my waste water from my tank or even fresh mixed salt water to my dogs..they get fresh ro water...I think that you would just asking for trouble... down the drain gets my vote...

I don't see why you couldn't water plants with the waste, as it is originally tap water. The chemicals are removed by the first carbon filter, and second if you have one. The membrane doesn't add anything to the water, it only releases a higher t.d.s. ( thus waste) due to the membrane effect of lowering the mineral content. Put the waste and r.o. water back together and you should still have what you start with. The systems I work with (residential) are a 3:1 ratio. Three gallons down the drain, and 1 gallon of product water. For those of us on metered city water you also have to factor in the sewer charges based on gallons of water used.
N.S.F. (government regulations) list r.o. water as having less than 20 p.p.m. and d.I. as less than 1 p.p.m. Just in comparison spring water is listed at less than 500 p.p.m. When I worked for the Culligan Bottled Water Division, spring water was around 375 p.p.m.

Don't drink d.i. water, it will actually remove your stomach lining! During the 90s the Yuppies in Toronto thought this was a new diet thing and suffered the consequences. D.I. is usually used in batteries.
