Good question,

Following reason to increase the pH

  1. The declining pH will cause the ORP reading to increase even if no chlorine is present.
  2. The pH difference after the RO depends on the composition of your input water source. The resultant pH will depend on the initial water chemistry.
  3. Depending on whether you have amounts of gases such as CO2 in your local water supply.
  4. The membrane got exhausted and not capable to remove alkaline minerals.
  5. Rejected water line got choked.
