Water line to fridge had a saddle valve, saddle valve started leaking so took it out and repaired pipe. Now trying to figure out how to reconnect fridge line. I have 1/2 inch copper under the sink and the pex line at the fridge says 1/8 on it. I can't find any adapters that go from 1/2 to 1/8,or even 1/4 to 1/8. Any help would be appreciated, thanks!
Dont use plastic water lines going to fridge I see them leak all the time. Use 1/4 flexible copper with compression fittings or 1/4 flexible braided stainless steel supply line(like going to your faucet) I have seen them up to 20' long.
The easiest ways is to install a compression nut T. You unscrew your supply line from your sink to the shut off valve and screw in the compression nut T. Your water line from sink and icemaker will both screw into this. Just take a trip your local hardware store and ask for help this is a very common issue.
