Water Tank Asm

Rich B for Model Number zisw480dm

Answer Hello Rich. Sorry, but there is no way of us knowing where your shut off is at for the water supply line coming to the refrigerator. However, you can turn off the main supply line for the home and shut all water off until the repair to the water tank WR17X11176 is completed.

Answer Hello Todd. You will need to replace the tank WR17X11176 and all the tubing that comes with it. You can not cut the lines going to the tank. Hope this helps.
