Flow Restrictor x1 Review: Works well with 75 gpd membranes in water saver system. - This worked great for my two 75 gpd ro membranes in series. I purchased my rodi water saver system used and it came with a 800 restrictor which caused low efficiency and I went through DI resin quickly. Since installing this my efficiency has increased quite a bit. Review: Well made ,make no noise ! - If you are looking for flow restrictor for your RO system, just get this brand. I ordered two other brands both come with 2 restictors they made very loud noise while my old original parts was very quiet. This one makes no noise just like the original one, half the price with much faster shipping. How could you not love this little parts! Highly recommend. ## Features - ★WATER&FOOD USE: Our Water flow restrictor is made from safe,non-toxic materials.
