RO Pump - Sanitize your system

The best time to do this is when you are changing your filters, preferably all 5 filters.


  • Drain the system, including the tank.
  • Shut off all valves (Point X and Point Z on figure 1).
  • Remove the 3 pre-filters and membrane but leave on the 5th stage polish filter.
  • Put about 2oz to 4oz of hydrogen peroxide or common household bleach into the first stage housing.
  • Turn on all the valves.
  • Fill 2 tanks of water and empty the 2 tanks of water out.
  • Re-insert the filters, the membrane and replace stage 5 filter.

You are done!
