Not sure what could be the cause. TDS out is 0. TDS coming in is 27 just like always. Water seems to be taking extra long. not coming out like usual. what could be the problem. any ideas? carbon and sediment are changed out every 2 months. have not changed di. since it has not changed color. never changed membrane. how do you know when its time to change the membrane?
