* KT-103, OPTIONAL Manual Flush Valve

* The system flushes itself when it is making water. In most cases a manual flush valve is not required.

* However, it'd be beneficial to manually flush the membrane if the water supply is from well or very hard water, above 600 ppm of TDS or Hardness.

**** NOTE: Flow restrictor is NOT included. The picture shows how to connect the flush valve to your system.
