Rodi tds

[valley]

Hello, I just added the brs water save upgrade, a booster pump, and I changed out my di resin and sediment filters on my brs 75gpd 4 stage unit. I used the unit yesterday and the water was coming out at 0 tds and I made a big batch of water. Now today the water is coming out at 3 tds. I’m not sure why this is happening if pretty much everything is brand new and I’m not sure what exactly I can do here. The unit is running at 80 psi and the carbon block and membrane are 6 months old. Any suggestions on what I can do?

Are you draining the water before you draw it? TDS creeps up that way

Flush the system for 10-15 minutes to clear out impurities, check for air leaks, calibrate the TDS meter, and ensure the DI resin is tightly packed. For more details refer to https://www.maxwaterflow.com/why-ro-ppm-is-high as it helped me too.
