Hi many thanks for your timeIs it an in-line tester or is it a pen type also wouldn't hurt to get a sample tested at your lfs to compare.
If it does compare and everything has been replaced as new all filters membrane and New di resin and pressure is fine if you have a Pen type tester and The cup your testing the water is clean and still getting a reading I don't think there's a lot more I can do to help unless someone can see something that I've missed.
