The Best Water Line Tubing to use when hooking water up to a Refrigerator

Learning about Fridge Water Lines

When hooking up a water line to a fridge ice maker or a fridge door water supply you want to use the correct materials to ensure the water flows well and everything is hooked up correctly with minimal chance of having any water leaks in the future.

Refrigerators come in many different sizes now some with the freezer on top some with a freezer on the bottom and some with the freezer beside the fridge area which are called a side by side fridge.

Something they all have in common regardless of where the freezer is or the cubic space inside is that they cool food freeze food and some supply water through the outside front of a door and some will make ice cubes for you as well. To have a water dispenser or ice maker in your fridge you need to be able to get water from your cold water supply to your fridge in an efficient way.

Something that you might not have considered is what types of plumbing material are you going to use to connect water to your fridge from the water line in your house. Even if you are hiring a plumber you should be aware of the different options available and what they mean to you.

There are a few choices of Refrigerator tubing you can use.

1) Copper tubing is a great choice and is affordable. Copper is durable and you won’t get a bad taste in your water or ice from the copper line as reported when using plastic or PVC tubing. The only problem I see with using copper is that it can kink easily. You will have extra tubing behind your fridge to enable you to pull your fridge out for cleaning purposes etc and it is quite possible that the line could get caught and kink causing the water flow to be blocked or worse the pipe to kink enough that a leak appears.

2) PVC or plastic tubing as mentioned under the copper tubing section is also an option. Plastic is very cheap to purchase which makes it very affordable. The problems with plastic tubing for some people are they have reported noticing a bad taste in their fridge water and ice. When they changed over the plastic tubing to copper tubing, they then reported the taste being non-existent. Another possible problem you might find with using plastic tubing to hook up a fridge’s water supply is that plastic is not a very strong product and cuts quite easily. For insurance purposes you might want to stay away for using PVC or plastic.

3) Braided stainless steel tubing is another option and is the option I recommend using. Braided tubing is a very strong and durable product that will not cut easily, kink easily and to my knowledge there are no fowl tasting water reports when using braided tubing. Braided tubing looks the same as the braided water supply lines you use to hook up a toilet or a sink to your hot and cold water lines. The only difference is the diameter which is only a 1/4” versus a ½” for toilets and sinks. The other notable difference is the length of tubing as a fridge supply can be 10’ to 25’ depending on where you are connecting from where a toilet or sinks are usually 12” or so. Braided tubing is fitted at both ends with the proper fittings so all you have to do is tighten the line to your connections. Braided supply line is also the easiest to work worth. It might cost you a few dollars more than your other options but it will last longer and like I said very easy to work with.

A valuable tip if you are hooking up your water supply line to your fridge yourself is to make sure you leave extra tubing behind your fridge so you can pull the fridge out to clean in behind it. Give yourself an extra 5 or 6’ of line. So if the distance from the refrigerator hook up to the water line you are tapping into is 10’ make sure the line you are installing is at least 15’ so you have room to pull your fridge out.
