Do you enjoy having an ice maker in your fridge? Maybe you get all your drinking water from the filtered water coming from the fridge? There are many conveniences that come with a modern fridge that has all these options, but it does come with an extra problem when installing your fridge. Having a water line to connect the fridge might not always be convenient.
Some choose to have their fridge in a location that is across the room for convenience, and in such cases, you might need to have new plumbing installed. This limits the options you have for a future rearranging of the furniture in your kitchen. The other option is to have the water line lying across the floor, and that could spell disaster if it was to get damaged and spring a leak. You should make sure that you have a shutoff valve on the water line to prevent flooding if there were to be a leak.
