1. Gather Your Tools and Materials
Before you begin, make sure you have all the necessary tools and materials. You’ll need:
- Adjustable wrench
- Pipe cutter
- Teflon tape
- Dishwasher supply line
- Dishwasher shutoff valve
2. Turn Off the Water Supply
Begin by turning off the water supply to your dishwasher. Locate the main water shut-off valve in your home and turn it off. This step is crucial to prevent any water from flowing while you work on the plumbing.
3. Disconnect the Old Shutoff Valve (If Applicable)
If you’re replacing an old shutoff valve, use your adjustable wrench to disconnect it from the water supply line. Be prepared for some residual water in the line.
4. Measure and Cut the Copper Pipe
Measure the distance from the dishwasher’s water supply connection to the location where you want to install the shutoff valve. Use a pipe cutter to carefully cut the copper pipe at the desired spot.
5. Apply Teflon Tape
Wrap Teflon tape clockwise around the threads of the dishwasher supply line. This will help create a watertight seal when you attach it to the shutoff valve.
6. Attach the Shutoff Valve
Screw the dishwasher supply line onto the shutoff valve until it’s securely in place. Use your adjustable wrench to tighten it, but be careful not to overtighten, as this can damage the threads.
7. Connect the Copper Pipe
Slide a compression nut and ferrule onto the copper pipe, then connect it to the other end of the shutoff valve. Tighten the compression nut with your wrench until it’s snug.
8. Turn On the Water Supply
Slowly turn on the main water supply valve to allow water to flow into the dishwasher shutoff valve. Check for any leaks around the connections. If you notice any leaks, turn off the water supply and tighten the connections as needed.
9. Test the Dishwasher
With the water supply turned on, run a test cycle on your dishwasher to ensure that it fills and drains without any issues. Keep an eye out for any leaks during this process.
10. Secure the Shutoff Valve
Once you’re satisfied that there are no leaks and your dishwasher is functioning correctly, secure the shutoff valve in its final position using mounting brackets or straps.
11. Clean Up
Clean up any debris and make sure there are no tools or materials left around the work area. Dispose of any old parts or materials properly.
12. Final Inspection
Double-check all connections and make sure everything is securely in place. This will provide you with peace of mind knowing that your dishwasher shutoff valve is installed correctly.

Plumbing a dishwasher shutoff valve is a manageable DIY project that can save you time and money. By following these steps, you can ensure that your dishwasher operates smoothly and without any water leaks.
