How to cap off water line to refrigerator?

Capping off the water line to a refrigerator is pretty simple. Disconnect the freezer pipe and clean it by turning the T-valve to halt the water flow. Flatten out the copper tubing and secure the cap in place with a twist. You can also close the water pipes to your refrigerator with a tap valve.

Is It Possible to Cut Off Line To A Refrigerator?

You may not want to use the ice maker of the refrigerator. In this case, it’s a good idea to cut off the water pipes. 

Water supply pipes can leak. As a result, it can damage the refrigerator, wiring, and flooring.

Water from a leak might see beneath your flooring. It can be costly. You’re also at risk of mold, which can quickly spread throughout your home. 

You might also notice a puddle of water rather than behind the refrigerator. Turning off the water supply valve is insufficient to keep the line from leaking.

Capping off the water line to a refrigerator saves you a lot of money. It’s more likely to be capping off a dishwasher drain

How To Turn Off The Water Line?

When it comes to securing a refrigerator’s waterline, safety is paramount. As you’re right up to wires and a potentially hazardous electrical outlet. 

For this project, you’ll need a good-quality water pipe cap and a set of tweezers. Here are some affordable water pipe caps you can find in the market:

Product 2

Now that you have all you need to start this project, let’s go through the steps.

Step 1 of 4: Pull The Refrigerator Out

Every project needs to start by doing the basic chores. Here is pulling the refrigerator. You need to remove it for your own good. Let’s look after the steps. 

Move the refrigerator out and aside from the wall with care. Keeping the refrigerator close to the wall might not be a wise idea. 

You’ll also need to check first if it goes next to a wall. You should also check it for french door refrigerators

You don’t have to pull the refrigerator all the way out. You only need it far enough to work properly.

You may notice water gathering under the refrigerator. In this case, the waterline needs to be capped as soon as possible.

Now, clean up excess water behind the refrigerator with a clean rag. This will keep mold at bay. It’ll also provide a better environment for you to work.

Step 2 of 4: Stopping the Flow of Water

You must now turn off the water supply to work in peace. This step is a must or else your work will be doubled rather than done. Let’s stop the mess. 

Firstly, look under your refrigerator for the T-valve. It’s simple to find because it’s shaped like a T and made of brass.

The T-valve might sometimes be found beneath your sink rather than behind the fridge. You may need to clean the refrigerator water line if you see any dirt.

Finally, rotate the T-valve clockwise till it comes to a complete stop. This will stop the flow of water. It’ll also allow you to operate safely without exacerbating the problem.

Step 3 of 4: Disconnect the Refrigerator Pipe

To cut off the water system line, you need to remove the refrigerator pipe. But for this step, you’ll need to be more heedful. Go after the steps attentively.

Identify the copper line that flows into somewhere at the back of your refrigerator. Then, lock onto the screw on the refrigerator pipe with a pair of little pliers.

To loosen the screw and pull it from the pipe, turn it counterclockwise. Remove the screw from the pipe. Then carefully pull it out of the refrigerator by hand. 

Both the screw and the refrigerator pipe should be saved for the future. You can detach the water pipe cap later.

Step 4 of 4: Put on the Cap

You’ve come to the final step after a long path. Take a deep breath. Let’s conclude this project. 

You need to ensure that the water pipe cap fits perfectly. For it, clean the wire with the help of a rag. 

Now place the cap on top of the tube. Then twist it and press it all the way down. 

Try not to overtighten the cap. Yet make sure it’s deep enough to keep water from pouring out.  

If you choose, you can detach the water pipe cap in the future. But there’s no need to. The water line cap prevents damage to your refrigerator, kitchen, and flooring. 

Finally, plug in the refrigerator to an electric outlet. Before you plug it in, check whether the refrigerator can share an outlet or not.

Is It Necessary To Cap Off The Water Line?

A refrigerator water line should not be capped, yet it is a good idea. Only turn off the water pipes if you aren’t utilizing them right now.

Even when not in use, a pipe can leak and rust. That is why most people seal them off.

Refrigerator water pipes, whether copper or plastic, are subject to leaks. A braided metal water supply line is the only type that rarely leaks. But it’ll cost you heavily. 

Capping off water pipes isn’t permanent. You can always remove it if you need to utilize the waterline again.

This is the end of our discussion. If you’ve maintained as I said, your refrigerator is now protected from leakage and damage.

Answer: The icebox of a refrigerator might have a leakage if the freezing drain becomes clogged. Debris, ice, and food scraps jam drain hoses can also be the causes. They cause water to overflow.


I’ve tried to calm your yearning regarding how to cap off the water line to refrigerator. You now know what you require to do if you don’t want leaks. 

You can also empty the line by inserting a pierced water saddle tap valve. When you don’t have any leaks, you’ll appreciate yourself doing this project.
