Rodi tds

[seeky007]

Hi everyone
I HAVE JUST INSTALLED A WATER BOOSTER PUMP ON MY RODI UNIT MY TDS IS 7 COMONG OUT OF THE CLEAN LINE AND THATS BEFORE THE DI STAGE IS THAT GOOD OR SHOULD I GET ANOTHER DI STAGE.

TDS of 277 into the membrane and 7 out is very good.

The DI stage will reduce that to zero

This.

DI should be able to take down to zero from 7, test the water coming out of DI.

Thanks
I will put a tds meter after the di stage that would the right move I think.

Yes, that's the one that tells you when you need to change the DI resin.
When the TDS increases to 1 or 2 change the resin.

If that happens too frequently a 2nd DI stage will prolong the time between changing the resin.

I have a single stage of DI resin and it lasts me about 6 months, but everyone has different results
