Help with plumbing RODI unit under sink

[Butchy21]

So I currently been using a faucet diverter (https://www.bulkreefsupply.com/chrome-faucet-diverter-valve.html) to hook up my RODI to a cold water source at my sink faucet (it has to be hooked up and unhooked for every use).  It has worked OK however recently I can't get a good seal.  The water sprays everywhere!  My guess is either the threading is screwed up or the gasket in the diverter is damaged.  I will be trying to find new gaskets but in the mean time I wanted to look into possibly plumbing the RODI unit directly into the cold water line under my sink.

 

I need a little help with this -  From my reading, it sounds like the steps would be:

1. Turn off cold water supply

2. Unhook the cold water line from the sink

3. Screw in an angle stop valve after the water stop valve - BRS sells one listed here.

4. Reattach cold water line to stop valve and then to the sink

 

This seems too easy- am I missing any other connections required?

That's how I did mine.  Pretty easy and straightforward.

Awesome- Ok, I was confused because someone mentioned to put in an angle stop and then a separate ball valve.  I figured it would work either way but I am not plumber ha.

I don't think a separate ball valve is required.  It looks like the angle stop has a valve on it to control flow to the rodi unit.
