Hi,
I'm having trouble with a RO installation. My TDS is reading at around 70. I have tried 2 different RO membranes and 2 different filter housings (different brands0. I have a whole house filter and TDS going into the RO filter is 350 ppm. Also, I have a pressure regulator, and I have dialed the pressure all the way to 60+ psi with no effect on the TDS.
I have inserted, re-inserted my membranes many times. I wonder if the waste water is by-passing into the permeate water outlet via the o-rings. Should they always be lubricated? Re-inserting the membrane seems to change the ppm which made me wonder about this.
Any insights would be appreciated.
Thanks very much!
