People who have it plumbed into an ATO (where it runs multiple times a day) may only need to flush it once or twice a week/2 weeks (maybe longer). It really doesn't take long, even flushing it for a minute or two is better than nothing, your DI resin & your membrane will last longer.
In this way, how do you change a Rodi membrane?
Disconnect tubing from membrane housing cap (typically on the right-hand side of the housing) by pushing down on the small ring where the tubing connects to the cap. Press and hold the ring down while you pull the tubing out. Step 3. Unscrew membrane housing cap from the membrane housing and remove the RO membrane.
Beside this, how do you clean a Rodi unit?
Turn off the water supply to the system. Remove all housings and remove all pre-filters and post-filters from the system including sediment filters, carbon filters, in-line filters, and deionization cartridges. Remove the reverse osmosis membrane(s). Wash housings with a soft brush or cloth in warm soapy water.
NOTE: The pressure gauge should indicate a pressure reading of > 40 PSI during this 15-20 minute test period. Rejection rates less than 95% may indicate that the membrane should be replaced. As a general rule; the RO membrane would be considered in good condition when the rejection rate is = to or > 95%.
