so after upgrading my 100 gpd ro unit to a 200 gpd unit i noticed my resin was perishing pretty quick , so i thought it must be my old ro membrane .
i changed back to 100 gpd using the new membrane and still its perishing pretty quick as in 0-3 ppm in about 250 litres, i ve only just purchased this resin so surely i couldnt of been sold a dodgy lot or could i ?
ive only had the ro unit a year and i ve already changed the three filters some months back , any suggestions anyone of whats gone wrong, all replys appreciated.
