Do I need another flow restrictor?

I added a second RO membrane to my RO/DI unit. Do I need a second flow restrictor? I would think one should be fine but wanted to check if a second one was needed before the second membrane.

The second one is running off the the waste water line of the first, correct? Then no, you don't need another flow restrictor.

if you want it to make more water you need a new one for the GPD

Yeah the second one is fed from the first. So if I have two 75 GPD membranes do I need a 75 GPD restrictor or a 150 GPD?
