RO to refrigerator ice line

[stonkers]

Hi! I have a reverse osmosis under the sink in my kitchen currently connected to a spout on the right side of my sink. This sink is on an island about 4 feet away from my refrigerator. As it stands my cold line (well water with high salt content, I'm in Florida) comes in and has a shutoff valve with 2 outputs that go, 1) to the sink cold, 2) to another shutoff valve that feeds under the floor to another shutoff valve in a plastic box behind the refrigerator (ice maker supply line). Between the #1 output, I have a splitter that connects to the green line of my RO to feed the RO system. That system connects to a pressure tank and the spout. The spout has 3 lines, 1) black that connects to my drain 2) red that runs back to the RO, and 3) blue that runs back to the RO. I'd like to do 1 of 2 things (really either is fine):

1) Instead of feeding the spout on the sink (I have a soap dispenser I can put there instead), feed the refrigerator line.
2) Feed both the spout in the sink and the refrigerator line (but now with RO water instead of nasty well water).

Can anyone tell me how to do this? Thank you very much in advance!

Depending on the age of your fridge, you may not be able to do it. Some newer models within the past few years require a certain pressure to accept water. The RO systems drastically cuts down pressure, so this doesnt work for some models.

I have taken a tee off the line going to the spout, and run the branch to the fridge. Be sure to give the fridge its own shut off valve.

contact manufacture of fridge..find out the minimum psi allowed to operate icemaker on that model

put a gauge on the out put of RO see what the psi is

go from there

Based on reading this info, it sounds like the DDP 5800 would be right for my application, crazy expensive...

Correct me if I am wrong. Water from an R.O. system must use a plastic tubing and not copper.
I heard somewhere that the water is so clean and void of most minerals that it will deteriorate the copper over time.

If the tubing going from sink to the box in wall is copper that may not be a good idea.

never seen that claim in any tech manuals. Only that someone told me this.
may have been an RO tech. If any one has a reference to that would be helpful.

Residential RO Systems/Membranes Questions

Can I use Copper Tubing for the RO Product Water?

No. Due to RO product water being very pure, it can leach the minerals from copper tubing which will cause a metallic taste in the water or ice, and cause the copper tubing to develop pinhole leaks over time.

Learn something every time I come on here. Thanx for pointing that out

I don't have any copper, all PVC except for the shutoff valves.

I found a good price on it, would this do the job right?

Then there is this one that looks like it would be a much easier install, but is used. Would you take a chance based on my light load application?
