I was given a rodi system by my good buddy . I’m in leander the water coming out of the tap is 375 ppm the system is a 5 stage. The water is a well shared by 900 homes. No chloramines. I am using New carbon blocks and new pre filter. It Turns brown after 55 gallons or so. It is a 1 micron sediment filter Installed New membrane. Water pressure is about 45 psi at the rodi It Goes through di resin fast after 100 gallons it looks like it is getting brown. The best I can get is 7 ppm. Then when I test the barrel it is 71 ppm. What am I doing wrong and what do I need to buy to fix it. On a budget. Help Sent from my iPhone using Tapatalk
