Pretty simple.. But ifound my RO system giving me a lot of waste compared to filtered water so when i would make water i would have to have a 40 gallon bin to use as a waste bucket just to fill up a 10 gallon rez and it was a huge pain in the ass to empy everytime i needed to make water. And my RO is located in the basement where there is a hose type faucet and no drain to just run the waste line too. Solution! Go to your local hydro shop and by some 1/4 in. Tubing and a plastic extention piece that they use in hydro and extend your waste line and run it some where. And If you have 2 seperate rez's and only one RO system you can buy quarter inch tubing and use a plastic T to seperate your filtered water to 2 seperate lines. Get 2 float valves and your good to go!
