Spectrapure rodi question

[jgraz]

I am in the process of setting up new line on a Spectrapure 90gpd system I purchased used.
Hen I took off the waste water line from membrane housing I found this in the line.
What is it? What does it do? Do I need it?
I imagine it is some sort of restrictor but who knows. I am running this with the AquaticLife smart buddie booster so that should already have the flow restrictor right?
Thanks in advance
John

It's a flow restrictor.

Thx
Yeah just did a bit of looking on Spectrapure site and found it.
As per Aquaticlife it has to go. Only uses the one located in the pump system

Thanks
