## How to Disconnect Plumbing Under Kitchen Sink
### Tools You’ll Need
* Adjustable wrench
* Basin wrench
* Bucket
* Flashlight
* Gloves
* Pliers
* Rags
### Safety First
Before you begin, remember to turn off the water supply to the sink. This is usually done by turning the knobs under the sink clockwise until they are tight. Also, place a bucket under the pipes to catch any drips.
### Step-by-Step Guide
**1. Remove the Access Panel**
Most sinks have an access panel under the sink that allows you to access the plumbing. Remove the screws or clips holding the panel in place and set it aside.
**2. Disconnect the Drain Line**
Locate the drain line, which is the larger of the two pipes under the sink. It is usually connected to the sink drain with a slip nut. Use an adjustable wrench to loosen the slip nut and detach the drain line from the sink.
**3. Disconnect the Water Supply Lines**
There are usually two water supply lines under the sink: one for hot water and one for cold water. Use an adjustable wrench or basin wrench to disconnect the water supply lines from the sink faucets. Be careful not to overtighten or damage the pipes.
**4. Remove the Garbage Disposal**
If your sink has a garbage disposal, you will need to remove it before you can disconnect the plumbing. To do this, first unplug the disposal from the electrical outlet. Then, use an adjustable wrench to loosen the bolts holding the disposal in place. Once the bolts are loose, you can pull the disposal away from the sink.
**5. Disconnect the Dishwasher Drain Line**
If your sink is connected to a dishwasher, you will need to disconnect the dishwasher drain line. This is usually done by loosening the clamp that holds the drain line in place. Once the clamp is loose, you can pull the drain line off the dishwasher.
**6. Cap the Water Supply Lines**
Once all of the plumbing is disconnected, you will need to cap the water supply lines. This will prevent water from leaking out of the pipes. To do this, simply screw on a cap to each of the water supply lines.
**7. Reattach the Access Panel**
Once all of the plumbing is disconnected and capped, you can reattach the access panel. Be sure to tighten the screws or clips securely.
**8. Turn On the Water Supply**
Once the plumbing is reconnected, you can turn on the water supply to the sink. Check for any leaks around the connections. If you find any leaks, tighten the connections until the leaks stop.
### Troubleshooting
If you encounter any problems while disconnecting the plumbing under your kitchen sink, here are a few tips:
* If you cannot loosen a nut or bolt, try using a penetrating oil.
