Thanks so much for asking, Lyn! So long as you have the proper electrical and spacing requirements, any Samsung refrigerator will operate as normal with or without a water line. A water line connection is only needed in order to use an automatic ice maker, water dispenser, or auto-fill water pitcher. Since your home does not currently have a water connection for the refrigerator, you would just need to turn off any ice makers, and you would not be able to use any water dispensing features. ^Jecca
