I recently bought a new refrigerator (Samsung RF263BEAESR) and am trying to connect it to my house's water supply line (under the kitchen sink). The prior owner of the house ran a copper line from the sink area to the general location of the fridge but neither end was hooked up and our prior refrigerator didn't have an ice maker.
I carefully reviewed the instruction manual for the new fridge but Samsung only provides instructions for applying a saddle valve on copper pipes. This won't work because my house has steel pipes that aren't easily accessible (besides, I'm not a fan of saddle valves to beginwith).
Here's a picture of the current water supply valves under the kitchen sink:
I'm hoping that I could replace this valve with something that will support a single 3/4" threaded steel input and have multiple outlets (one going to the sink faucet -- threaded 1/2" I think -- and another going to the copper compression fitting). Do this approach make these? Is this a bad idea? Does the refrigerator line need to be on a completely separate connection to the house water?
