Flow restrictors are essential to a properly functioning RO system. Be sure to have the appropriate flow restrictor for the membrane you have. If you decide to change your membrane to a higher or lower GPD membrane, you must also replace the flow restrictor to correspond with the membrane.
All BRS Reverse Osmosis Systems have the appropriate flow restrictor installed.
The 75 and 100GPD flow restrictors are barrel models. The 150GPD is a capillary flow restrictor, which is the stem style that goes inside of your RO units waste water line, and can be trimmed if desired for optimal results.

Product Questions
We like to recommend that the flow restrictor be replaced with every change of the membrane. Thanks!
If you were to find another 50 GPD membrane you will not need to change the flow restrictor. The same flow restrictor will be used on the single waste water line coming out of the second membrane. Feel free to let us know if you have any further questions!
If you have 75gpd membranes then the 550 would be the correct flow restrictor :)
As long as you change the flow restrictor to the 100gpd to match your 100gpd unit, you can run the 100gpd membrane.
The flow restrictor always goes on the waste water line. They come in a few different varieties including some that are on the inside of the tubing. Your unit likely wouldn't have worked without one so pretty good bet its hiding there somewhere.
No you should not. You want to keep your existing 75gpd flow restrictor :-)
It goes on the waste water line out of the membrane.
