I need to run a refrigerator supply line for a new (additional) refrigerator that I just put in my basement. I currently have a refrigerator supply line that runs from the basement up into the kitchen as you can see in the image below. My original though was just to remove this valve and replace it with a shut-off that had 2 1/4" outlets, one outlet would attach to the existing line and the second I would connect to the new run.
The problem I have run into is that I can't find a valve that has dual 1/4" outlets, the best I could find is a valve with a 3/8" outlet and a 1/4" outlet. I am guessing since I can't find a valve with 2 1/4" outlets there is something "wrong" with my approach.
I assume that the best way forward here would be to replace the current valve with a valve with 3/8" and 1/4" outlets, connect the current supply line to the 1/4" out and then run some 3/8" copper to the location where the new fridge is, and the put a 1/4" shutoff on the end of that run to actually connect the refrigerator supply line.
This feels "clunky" to me, although I am not a plumber so there might be a reason why I wouldn't want to split the line into 2 1/4" outlets.
Any advice on my approach here would be helpful, specifically is there a better way to do what I want to do?
