I have a 4 stage RO/DI filter, and I have decided to do some maintance, and flush the membrane.
The RO Membrane, has three lines connected to it. 1 Yellow line from the prefilters, 1 Red line they discharges the waste water, and 1 Blue line that leads to the DI canister.
The directions for flushing the membrane say to switch the red and blue lines, and run water for 15 minutes. As I look at this, It appears all this would do, is dump a bunch of waste water into my DI filter, which does not seem right.
Does this seem like a misprint to anyone else? I would think to actually 'flush' the membrane I would need to switch the yellow line from the prefilter, with the blue line for the pure water.
Any thoughts?
