One of the most important factors in the operation of your RO DI system is pressure. Running an RO system at too little pressure causes under production and over waste. Not to mention the fact that the membrane is unable to operate correctly and the output water will be higher in TDS. You use a TDS meter to test the quality of the output water but do you know the pressure your system is running under? You could be throwing away DI after DI simply because your RO is not working as well as it should. This is the next step in knowing exactly what is going on with your system!
