I might have to downsize my water production to a more compact solution. What kind of real life production are you getting from 4021 ro’s. I’ve got good pressure/flow, tap TDS is 280-300ppm. Currently have a 4040 doing about 2lpm. I generally use around 350l a day very occasionally 700 but can handle that with storage.
