My ro/di unit is doing roudly 1:1 to 9:10 good water to waste water.   I would think it would be closer to 1:4.  What does this mean?

Have you tested the TDS before and after the membrane to see if it is still good? Maybe there is a hole in it and it is passing water without filtering it.

Yeah. I am ordering one online right now.  I have two RO units.   An older one that seems to be about 4:1 but I don't know how old the membranes are and a newer one but it seems to be going way to fast. But Its annoying I have about 3-4 gallon a day evaporation on my tank.  All figure it out. just means a couple trips the LFS for RO till the unit arrives.
