my ro unit water reads 0 on my tds meter i just changed out the membranes sediment carbon and pro resin i tested the water comin out from the unit and it reads 0.01 what do i do to make it 0

Have you run a few gallons thru the new membrane? Some times you just have to let it run a little while. It should read 0 after a few gallons made.

I flushed it for a couple of minutes but noticed that the carbon blocks were a little cloudy when I turned on the unit but it went away after awhile could that be the problem

When you switch out the carbon, you would have to run it for like 15 minutes to clear. Also flushing the membrane a few minutes before and after use will prolong membrane life

made 30 gallons for a watwr change and it still reading phosphates so really dont know what 2 do now should I flush it or do I replace the carbon filter?

How many stage RO / DI you have? Do you just have TDS meter on the output of the DI?

 

[jkidd155]

7 stage pro kit 300gpd
1 Sediment filter
2 carbon blocks
3 resins
Tds Meter is where the reason stages are

 

[Rebels23]

I'm not sure then. If your TDS is reading zero, you shouldn't get a phosphate reading. Are TDS meter pins plugged in the right way (has to face a certain direction)? How many TDS meters do you have hooked up?

Spoke to brs they said I should use a freshwater tester for my ro water if not add salt then use my Hanna checker
