| 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. |
