Hi guys. I have a Pure Freedom van setup. When I first got it my tap TDS was 80ppm. Now, in the last few weeks, for God only knows what reason, it has shot up to as high as 450ppm! Anyways, I'm looking to get it down as much as possible as I'm obviously burning through a lot more resin. Firstly, my RO (4040) seems to be operating at only around 90% bringing 450ppm down to around 45ppm after the RO. Is this maybe due to my tap pressure, which is 35psi when it hits the RO...? Is this pressure too low and is that why the RO is only operating at 90%?
