How is the Sepa System repassivated?
A. Passivation is a process that will remove free iron deposits and will add future protection to your Sepa System. To passivate the Sepa System, swab the entire unit with either a 20% Nitric Acid (1st choice) or Phosphoric Acid (2nd choice) solution. Make sure to use good Nitric Acid or Phosphoric Acid handling precautions such as gloves, eye goggles, etc. when performing passivation. Rinse unit off with conditioned water such as distilled.
