RODI Flush valve

[reefrealtors]

I’m filling up some fresh water , do I leave this the way it is , or is it suppose to be in the direction with the broken lines ? I didn’t flush before using as I’m barely finding out about this .

Its a by pass flush valve for your ro membrane. My air water ice unit has 1.
When you 1st turn it on. Flush the units filters for maybe 2 minutes before turning the knob and making pure rodi.
Just adds life to your ro embrane. you should hear the air or have flow decrease when its on and active.

I flush mine for at least 20 minutes before I start making RO/DI water. My TDS are super high after not using the unit for several hours or days.

The tds going into the unit from the supply matters too.
Where i live the tap drinking water is only 32 or so tds.
I dont remember if its ppm or ppt but i can basically get away with a single di resin unit if i wanted and just change the di resin contantly. Would not be cost effective but i could do that.

When the lever is positioned the way it is in the picture, the flow is restricted, which raises the pressure on the RO membrane, causing production of RO water. When the lever is turned to FLOW, the flow is no longer restricted, dropping pressure so RO water is no longer made, and flushing any built up sediment from the membrane.
