RO/DI unit currently reads 0 TDS on Hanna TDS meter. Dowfilmtec 90 GPD membrane & resister, refillable DI (save operating cost), flush kit, no leaks. Originally $299 + $25 for flush kit. Asking $140 cash (no trades at the moment). Can deliver to Fullerton & OC areas. I may have spare DI resin to through in.
