Step-by-step Instructions for How to Run Water Line to Fridge Under Floor

Step 1: Inspect the Area

Before you begin, inspect the area where you intend to run the water line. Look for any potential obstacles such as pipes, wires or other appliances that may be in the way. To successfully run a water line under your floor to your fridge, you will need several tools and materials. These include a drill with a long drill bit, a pipe cutter, a shut-off valve, copper tubing, and compression fittings.

Step 2: Determine the Route

Decide on the route that your water line will take. This should be the most direct route from your fridge to the nearest water supply. Keep in mind any potential obstacles and plan accordingly. Before you start drilling or cutting any pipes, make sure to shut off the main water supply. This will prevent any accidental flooding in case of a mistake.

Step 3: Drill Holes

Using the drill and long drill bit, carefully create holes in the floor along the chosen route for your water line. Make sure these holes are large enough to fit the copper tubing. Use a pipe cutter to cut the copper tubing according to the length of your desired route. It is recommended to add an extra few inches for flexibility.

Step 4: Install Shut-Off Valve

Attach a shut-off valve onto one end of the copper tubing. This will allow you to easily control the flow of water to your fridge. Thread the copper tubing through the holes you have drilled in the floor. Make sure to leave enough slack for flexibility and to avoid any kinks in the tubing.

Step 5: Connect Shut-Off Valve to Water Supply

Connect the shut-off valve to the water supply using a compression fitting. This will ensure a secure and leak-free connection. Using another compression fitting, connect the other end of the copper tubing to the back of your fridge. Make sure it is securely attached.

To Wear Appropriate Protective Wear

What is the Best Method for Running a Water Line to Your Fridge Under the Floor?

The best method for running a water line to your fridge under the floor will depend on the layout and construction of your home. However, there are three main methods that are commonly used:

  • Through the Wall: This involves drilling a hole through the wall behind the fridge and running the water line behind cabinets or along baseboards until it reaches the refrigerator.
  • Through the Floor: This method involves drilling a hole through the floor directly below the fridge and running the water line up through the floor.
  • Underneath Cabinets: If your cabinets are located near your refrigerator, you can run the water line underneath them to reach the fridge.

Before choosing a method, consider factors such as ease of access, distance between fridge and water source, and any potential obstacles in the way. It’s always a good idea to consult with a professional plumber for advice and assistance in determining the best method for your specific situation.

How Do You Properly Connect and Secure the Tubing to the Fridge and Water Source?

One of the most important aspects of running a water line to your refrigerator is properly connecting and securing the tubing. If done incorrectly, it can lead to leaks, water damage, and potential health hazards.

In this section, we will discuss how to properly connect and secure the tubing to your fridge and water source. Before you begin connecting the tubing, make sure that you have the necessary materials and tools. This includes a refrigerator water line kit, a drill, screws, and a compression fitting.

Water Line To Fridge Under The Floor

First, you will need to locate the water source in your home. This is typically found behind or under your sink. Make sure that the water supply valve is turned off before beginning any work. Next, you will need to drill a hole in the floor or wall, depending on where your fridge is located.

Be sure to drill the hole in a location that is easily accessible and can accommodate the tubing. Once you have drilled the hole, you can begin connecting the tubing to the water source. This is typically done using a compression fitting, which will ensure a secure connection.

Are There Any Alternative Methods for Running a Water Line to Your Fridge Without Going Under the Floor?

While running a water line under the floor is the most common method, there are alternative methods that you may consider. One option is to run the tubing through cabinets or walls, as long as they are easily accessible and can accommodate the tubing. This may be a better option if you do not want to drill into your floors or if your fridge is located far from the water source.

Another alternative is to use a saddle valve, which attaches to an existing water supply line and allows for the installation of a new refrigerator water line without any drilling or cutting into the pipe. However, it is important to note that saddle valves can be less reliable and may not provide enough water pressure for your fridge.

Are There Any Ongoing Maintenance Tasks You Should Be Aware of Once the Water Line is Installed?

Once you have successfully installed a water line to your fridge, it is important to keep up with some ongoing maintenance tasks in order to ensure the longevity and effectiveness of your new water line. Here are a few things you should keep in mind:

  • Check for leaks periodically: Even if you have properly installed the water line, there is always a chance that a leak may occur over time. It is important to regularly check for leaks and address them immediately if you notice any.
  • Replace filters as needed: If your fridge has a water filter, it is important to replace it according to the manufacturer’s instructions. This will ensure that your water remains clean and free of contaminants.
  • Clean the water line annually: Over time, mineral deposits and other debris may build up in your water line, affecting the flow and quality of water. It is recommended to clean the water line at least once a year to prevent any potential issues.
  • Monitor water pressure: If you notice a decrease in water pressure from your fridge’s dispenser, it could be due to a blockage or issue with the water line. Check for any obstructions and make sure the water line is not kinked or damaged.
  • Keep an eye on the ice maker: If your fridge has an ice maker, it is important to regularly check for any issues such as clogs or malfunctions. Follow the manufacturer’s instructions for proper maintenance and troubleshooting.

By keeping up with these ongoing maintenance tasks, you can ensure that your newly installed water line to your fridge continues to function properly and provide you with clean, fresh water for years to come. So, it is essential that you take care of these tasks regularly in order to avoid any potential problems down the line.

Checking For Leaks


In conclusion, running a water line to your fridge under the floor is a task that requires careful planning and execution. It is important to follow all safety precautions and guidelines in order to avoid any potential hazards.

Firstly, it is crucial to choose the right materials for the job. The type of tubing you use should be able to withstand high water pressure and temperature changes without bursting or leaking. It is recommended to use flexible copper tubing or PEX (cross-linked polyethylene) tubing for this project.

Before beginning the installation, it is necessary to shut off the main water supply and drain any remaining water in the pipes. This will prevent any potential accidents or mess during the process. Next, carefully plan out the route of the water line from your fridge to the nearest water source. I hope this article has been beneficial for learning how to run water line to fridge under floor.
