Water line to fridge - necessary or not?

[Andrew Perkins]

We just purchased our first rental property and purchased a new refrigerator with an ice/water dispenser because I mistook an old gas line on the opposite side of the refrigerator as a water line. A plumber estimated that it would cost around $500-$600 to run one from the attic to the refrigerator. Should I pay to have this done or would it be acceptable to have the ice/water portion of the refrigerator not working? The refrigerator is non refundable.

Thanks!
