My RODI set up is in the basement where I hope to complete a fish room at some point for sump, fuge etc. I'd also like to plumb a separate system to my toilets to use the waste water. Currently I store waste water in several large drums for various uses depending on the season. For the waste water to toilet deal, I'd like to get a separate, fairly large pressure tank and tee into the cold water lines with a combination of shut off & check valves to make switching over from normal to waste on the toilet fairly quick & easy. I guess the tricky part will be transferring the waste from the large collection containers to the secondary pressure tank system. I reckon this can be done with a small booster pump & pressure switch combo. You could even recycle some of the other 'grey' water produced from showering/dishwashing this way, although a screen filter may be required & maintained for the dishwater depending on how 'lumpy' that gets.
Here's my set up in the basement, t'd into the washing machine cold line. Maybe I'm living in the past, but I like my copper piping. I have no problem sweating my own connections with copper fittings. I'm blown away at the price of the relatively simple looking pliers used to install some of the newer plastic pipe! I can buy a lot of solder, fittings & propane for the price of one of those.
You can see I managed to snag some larger JG type fittings to nicely adapt a pressure guage and go from the copper down to the 1/4 inch RODI tubing. I also tweaked the PRV in my house to give me between 82 & 86 psi, so the pressure guage at the input comes in handy. I have a second pressure guage installed at the RO membrane so when the differential pressure between the two gets into the mid 20s, I know it's time to start looking at the pre filters.
