## How to Plumb a Refrigerator Water Dispenser
Installing a water dispenser in your refrigerator can be a great way to have access to cold, filtered water at all times. However, if you’re not familiar with plumbing, the process can seem daunting. Follow these steps to safely and easily plumb your refrigerator water dispenser.
### Tools and Materials You’ll Need
Adjustable wrench
Phillips head screwdriver
Flat head screwdriver
Drill
1/4-inch drill bit
3/8-inch drill bit
1/2-inch drill bit
Hole saw (optional)
Pliers
Teflon tape
Compression fitting
Saddle valve
Copper tubing
Water filter (if desired)
### Step-by-Step Instructions
#### 1. Turn Off the Water Supply
Before you begin, turn off the water supply to your refrigerator. You can usually do this by locating the main water shut-off valve for your home and turning it clockwise.
#### 2. Remove the Old Water Line (if necessary)
If your refrigerator has an existing water line, you’ll need to remove it before you can install the new one. To do this, use an adjustable wrench to loosen the compression fitting that connects the water line to the refrigerator. Once the fitting is loose, you can pull the water line off of the refrigerator.
#### 3. Drill a Hole for the New Water Line
If your refrigerator does not have an existing hole for the water line, you’ll need to drill one. Use a 1/4-inch drill bit to drill a hole in the back of the refrigerator, near the bottom. The hole should be large enough to accommodate the copper tubing.
#### 4. Install the Saddle Valve
The saddle valve is a device that allows you to tap into an existing water line without having to cut it. To install the saddle valve, follow these steps:
1. Place the saddle valve over the water line, in the location where you drilled the hole.
2. Use a Phillips head screwdriver to tighten the screws on the saddle valve.
3. Use a flat head screwdriver to pierce the water line.
#### 5. Connect the Copper Tubing
Cut a length of copper tubing to the desired length. The tubing should be long enough to reach from the saddle valve to the water dispenser on the refrigerator.
Apply a small amount of Teflon tape to the end of the copper tubing. Screw the compression fitting onto the end of the tubing.
Connect the compression fitting to the saddle valve. Tighten the fitting with an adjustable wrench.
#### 6. Install the Water Filter (optional)
If you want to install a water filter, follow the manufacturer’s instructions for installation. The filter will typically be installed inline with the copper tubing.
#### 7. Connect the Water Line to the Refrigerator
Connect the other end of the copper tubing to the water dispenser on the refrigerator. Tighten the compression fitting with an adjustable wrench.
#### 8. Turn On the Water Supply
Turn on the water supply to your refrigerator. Check for leaks at all of the connections.
#### 9. Flush the Water Line
Run water through the dispenser for a few minutes to flush out any debris or air bubbles.
### Troubleshooting
If you encounter any problems while plumbing your refrigerator water dispenser, try the following troubleshooting tips:
No water is dispensing: Check to make sure that the water supply is turned on and that the water line is properly connected to the refrigerator.
Water is leaking: Check for leaks at all of the connections. Tighten any loose fittings.
Water is not cold: Make sure that the refrigerator is set to the coldest setting. If the water is still not cold, check to see if the water filter needs to be replaced.
### Tips
If you are not comfortable plumbing your refrigerator water dispenser yourself, you can hire a professional plumber to do it for you.
Be sure to use Teflon tape on all of the connections to prevent leaks.
If you are using a water filter, be sure to replace it regularly according to the manufacturer’s instructions.
### Conclusion
Plumbing a refrigerator water dispenser is a relatively simple task that can be completed in a few hours. By following these steps, you can safely and easily install a water dispenser in your refrigerator and enjoy cold, filtered water at your fingertips.
