What the freak is going on here?!?!
I installed the new membrane from BRS today in which I am very thankful for! However, it still didn't solve the issue. TDS after the membrane is actually higher now at 32.
After installing, I disconnected the line coming out of the membrane that goes into the DI and I ran the unit for 1 hr bypassing the DI with the flush valve off as suggested. You can see exactly where I bypassed in the video below. During this hour I continuously checked the TDS coming out of the RO membrane with my hand held and it never dropped below 38 TDS.
After that I hooked the DI backup and and flushed for another 5 minutes and now I'm getting 32 after the membrane going in to the DI with both the handheld and the inline TDS meters.
I verified once again that my tap water is 172. I can't figure it out but I'm only getting like a 80% rejection rate which is not right. Could it be that the housing for the membrane is bad?
Below is a link to a video I'm hoping you guys can check it out just to verify my line placements and you can also see where I bypassed the DI
