Water saving................

[woodcarver]

Hey Steve . The FAQ you are referring to applies to their regular R.O. systems. You need to look up their zero waste model . As it says the waste is fed back into the hot water plumbing so NO water goes down the drain.
As Chad pointed out it is a very simple concept but nice to see it on the market and could be a consideration especially for someone without R.O. and contemplating purchase.

you got a link for that one? I would have to read that as it doesn't make sence as that would put the same pressure on both sides of the membrain.. so either I am not thinking right or they are doing something different

The use a pump to push the waste water into the hot water tank.

Website is down so I cannot get a link

Thanks Chad !


Steve the Watts site is up and if you search for zero waste R.O. they have a schematic .
Sorry not sure how to send link

so the pressure of the booster pump forces the membrane by-pass water back into supply, overcoming the city pressure to a max of 80 psi?

I wouldn't waist the money on it. at 25gpd it is a very small system and by the looks of its set p you couldn't really put a 160 gpd membrane in there as the hot water system can only handle so much waist before it would over pressure and cause problems.

seams to me to be a fake tree hugger effect.. save water, but use more electricity.

anyhow you can always rout the discharge of a normal ro unit to a big container and use it for watering the garden, or making the kids a hockey rink, or taking a bath..
