meh

This didn't operate any better than the one already in it. Had nothing but problems with my captive purity unit since day one, so ended up buying a different unit that works great!

Great

I rexently upgraded my rodi from 50 gpd to 100 gpd, so I needed a new restrictor. This product shipped fast, was easy to install and is working great.

Nothing Fancy

They seem to do their job well. I purchased the 75 gpd for maintenance use on my Captive Purity and I have noticed any change for ratio of production to waste water.

Too short :(

I thought there would be some wiggle room for adjustment but the 60gpd restrictor came with a very short tubing length. Now my waste ratio is more than 6 to 1 - not good. Can't add length to this to adjust so I'll have to call it a loss and put my 40gpd restrictor back on and cut a little more off that tubing length. FYI - System installed is 60gpd Spectrapure ro/di 4 stage with booster pump (70psi)

75-100 GPD flow restrictor

If your pressure is not at the high end this product may not work for you on the Spectra-Pure units. My pressure is at about 50psi, and the ratio out of the box is about 5-1 (Five waste to one pure). Part of this may be due to the fact that it is winter, and my water is a bit on the cooler side. If the tube were longer the ratio could be adjusted. I will try one with a longer tube and see if I can use this during the summer months.

Great Flow Restrictor

This Flow Restrictor installed with ease and gave me the 4 to 1 ration i was looking for without having to cut it. I had bought a in-line restrictor and i wasn't working for me. I have the 75 gallon per day setup great buy!
