In cases like this, it's wise to put a second RO cartridge. Test the water coming out of the second RO cartridge on a regular basis, and when it gets up to 15-20 ppm, throw away the first RO in line, put the second RO into the first spot, and put a fresh one into the second spot. Be sure to change out the sediment and carbon filters every 6 months (no matter how much you use it). Change out the DI resin as soon as you get 1 ppm tds. You should be able to achieve 0 ppm tds this way, and if you swap the two ROs like I suggested you actually won't burn through many more RO cartridges than if you were only running one.
