I’m having issues with my RODI unit from Brs… it’s a 100GPD 4 stage with upgrades(2 di canisters) two carbon blocks(5 micron and 1 micron) I jus changed all filters today changed membrane two months ago. Everything was fine RO after di was 0 now it’s been stable at 7 and water after membrane is stable at 6 I’m confused I haven’t done anything special besides adjust tds probes properly in correct alignment and it hasn’t seen 0 since…..
