Rodi fitting

[Koddie Doo]

What is the RODI fitting that I would need to connect my RODI input to the cold water side of facet? I went to Home Depot and came back with something that did not work. I have a valve that I can use for on off. Just looking for the correct fitting to make this work.

Do you have a picture of what you currently have? There are several different ways of doing it. You could use a saddle valve which surrounds and pierces a copper pipe, I believe there is a fitting that will go between the cold water line and the line that runs to the faucet, there are fittings that connect on the faucet itself. If you have PEX you can get a quick connect fitting that you put inline with the PEX, that's what I did for my RODI unit.

If you can change you cold water shut off valve under the sink from just a 3/8 to a 3/8 and 1/4. This 1/4 can connect to your RO/DI inlet. Something like this https://www.lowes.com/pd/Keeney-Bra...-Compression-Quarter-Turn-3-Way-Valve/3191041

I was going to have something between the copper piping and the braided facet connector that would have an outlet.

The one I linked is plastic, but they make metal ones as well.
