The Membrane Flush/Flow restrictor valve is an all in one flow restrictor equipped with a flush valve for easy worry free use.
Keeping the flush and flow restrictor in a single package keeps fitting count down which means less chance for possible leaks or failures down the line.
- 550 mL/min for 75 GPD single membranes or 150 GPD Water Saver Systems
- 800mL/min for 100 &150 GPD single membranes or 200 GPD Water Saver System
Reverse Osmosis membrane flush/flow restrictor valves increase the flow to the membrane by bypassing the flow restrictor when the valve is opened. This helps flush deposits and significantly increases the usable life of the RO membrane. The Membrane Flush/Flow restrictor valve is an all in one flow restrictor equipped with a flush valve for easy worry free use. Keeping the flush and flow restrictor in a single package keeps fitting count down which means less chance for possible leaks or failures down the line. BulkReefSupply.com recommends flushing the membrane before and after each use for a few seconds, or every few weeks for a few minutes as part of regular reverse osmosis system maintenance. When the handle on the valve is “in line” the valve is bypassing the flow restrictor and is in “flush mode,” if the handle is perpendicular to the valve then the unit is ready for normal use.

Thank you for reaching out to us. Yes, that is the correct flush valve.
Please let me know if you need anything further and take care!
With the 75GPD membrane we recommend a 550ml or 500ml flow restrictor.
Please give us a call on Monday, there are a few things that could cause this. 763-42-9691
When the black valve is at 90 degrees or perpendicular to the flow restrictor it is closed and should stay like that for normal operation. When the black valve is inline or parallel it is open and flushing the membrane and pre filters.
I have better more important things to do than waste an hour on this. What a joke!
The Membrane flush will be installed on the black waster water line exiting the membrane. This contains the flow restrictor and flush valve all in one and will be the only item on the black waste water line before the water enters the drain.
Also what size would be appropriate for a unit that has a 120 GPD membrane?
When in flush mode a small amount of product water will still trickle out however most of the water will bypass and be sent down the waste water line. The 600 mL model will send more water to the RO membrane producing more water of slightly less quality, the 800 mL version will send more water down the waste and produce slightly cleaner water. Feel free to let us know if you have any further questions!
