membrane exhausted?
I've had my ro unit for 2 years and have yet to change the membrane I am diligent in changing the filters and di. The unit never showed a reading over 2ppm.
I have been having some po4. Issues with po4 being. . 08 to.16 after wc then falling. So I tested my ro water and found. 08.
Is this the membrane that needs.to be changed.
