I am attempting to hook-up a water line from our water filter to a refrigerator. The refrigerator already has a 1/4" copper line connected to the refrigerator that runs about half way to the water filter. The water filter has a 1/2" PEX output (currently to a sink water dispenser). I need to add a tee to that line, then run PEX to connect to the copper. At some point I have to reduce from 1/2 to 1/4. I was originally looking at Sharkbite, but they don't have a 1/2" to 1/4" reducing coupler. Watts quick connect does have a 1/2 to 1/4 reducing coupling, but for some reason, those don't seem as robust as Sharkbite. I don't want a flood. Any recommendations? Any help is much appreciated!
