I’ve had this RODI unit for a long time and never had problems before today. I got all new filters for the unit and ran the housings through the dishwasher. I was able to fill a 55 gallon tank and 3/4 of the 120 with 0 TDS water. Soon as I seen 1 TDS I changed the DI filter. Now I have 2 TDS. The only thing I can think of is the RO membranes are from the LFS this time 2 75GPD and I was running membranes from HomeDepot witch didn’t say how many GPD. Before the filter change I was filling a five gallon bucket in about hour and a half with 2-4 TDS before DI. Now filling buckets just under an hour with 10-12 TDS before DI. Maybe I have the wrong flush valve or reassembled wrong? I just pulled the filters and checked the O-rings and gaskets.
