What is the annual sanitization procedure?
We recommend sanitizing reverse osmosis systems at least once a year. The best time to do this is while changing your filters. First, shut down the reverse osmosis system in the same manner as with a filter change. Drain the system, including the tank, and then disconnect the blue tubing from the shut-off valve to the tank. Put about ¼ to ½ teaspoon of hydrogen peroxide or household bleach into this tube, using an eyedropper for best results. Reconnect the blue tube to the shut-off valve and follow normal Start Up procedures, including draining the tank. If you have an icemaker hook-up installed, be sure the ball valve in the line to the refrigerator is in the closed position during this procedure.
