I purchased a 6 stage 100GPD RODI unit from purewaterclub.com. Everything was going well for about the first 400 gallons (I have a 200G system) and then TDS started to creep up. I changed the 2 DI filters and it went back to 0. After about only 20-60 gallons later TDS started to creep up again. This time I changed the first 3 sediment filters. That didn't help at all. So I changed both DI filters again. This brought me back to 0 TDS but only for about 20 gallons this time. I tested my tap water and it reads 285 tds. I tested the water after passing the RO stages and it reads 185. The only filter I haven't changed at this point is the RO membrane. Question is should I bother changing it and both DI filters again or just scrap it and buy a 7 stage BRS RODI system?
Also worth noting is I did a ICP test and it read about 750ug/L silicone and I am battling dynoflagelletes.
Any input is greatly appreciated.
