Spectrum 4040 ro

Hi anyone using a spectrum 4040 ro? If yes what TDS results are you getting from it? Having trouble getting my new membrane below 20tds from 315tds. Is this normal?

That's with a booster pump.

its not a million miles away, around 93-94% rejection rate. I would expect it to be a little better than that, but not a huge amount.

If everything is set up then you should get 98% rejection rate. Speak to whoever you purchased from and with their technical experience they will be able to resolve it.
