Ordered a new fridge and they tried to deliver and install, but saying I need a new water line. Never had any issues with the current line and it is a copper water line. Icukd understand if it was plastic or old but good shape and hasn’t been touched since it was installed. Any reason I can’t use the same line and attach to the new fridge? I may just have them deliver and I’ll hook it up to the line if they won’t.
