![]() I've been testing the water from my RO unit throughout the day for a week or so now. I do it when I notice that my topoff unit kicks in. When it does kick in it puts water into the sump for about 5 seconds and then shuts off. The TDS of the water coming into the tank ranges from 65 to 150ppm. Not good. If it were to run for a good minute or two it would be great as after running for 15 seconds it gets back down to 0ppm. But the way it's going right now it's adding crappy water to my sump.

![]() I also have the same problem with the first water at reading being around 50's. I think this is the water that sits in the RO unit for awhile. Then the water levels out with a lower reading when ran for a minute.This is what goes into my container, test the water in my container and it reads 5ppm. This is the water that goes into sump.I can live with that.

![]() I agree. But when my float switch drops & the RO starts it doesn't run for a minute. It stops well before that. So it never gets to the point where the water tds levels out with a lower reading. It also is supposed to deplete your DI resin much faster to be intermittently starting & stopping your RO unit. Much better to run it for 5 gallons & stop it.
