## How to Build a Drain for a Kitchen Sink
Installing a new drain for your kitchen sink is a relatively simple plumbing project that can be completed in a few hours. By following these step-by-step instructions, you can save yourself the cost of hiring a plumber.
### Materials You Will Need
* New drain assembly
* Plumber’s putty
* Adjustable wrench
* Channel-type pliers
* Hacksaw
* Tape measure

### Step 1: Remove the Old Drain
1. Place a bucket under the sink to catch any water that may drain out.
2. Using an adjustable wrench, loosen the slip nut that holds the drain assembly in place.
3. Carefully remove the drain assembly from the sink.
### Step 2: Measure and Cut the New Drain Pipe
1. Measure the distance from the bottom of the sink to the top of the drain hole.
2. Cut the new drain pipe to this length using a hacksaw.
### Step 3: Apply Plumber’s Putty to the Drain Flange
1. Roll a rope of plumber’s putty into a circle that is slightly larger than the drain flange.
2. Place the putty around the edge of the drain flange, making sure to press it into the flange’s grooves.
### Step 4: Install the New Drain Assembly
1. Insert the new drain assembly into the drain hole.
2. Tighten the slip nut onto the drain assembly using an adjustable wrench. Do not overtighten the slip nut.
### Step 5: Connect the Drain Pipe to the Drain Assembly
1. Insert the drain pipe into the drain assembly.
2. Tighten the slip nut that connects the drain pipe to the drain assembly using an adjustable wrench.
### Step 6: Connect the Drain Pipe to the Trap
1. Insert the other end of the drain pipe into the trap.
2. Tighten the slip nut that connects the drain pipe to the trap using an adjustable wrench.
### Step 7: Test the Drain
1. Turn on the water and let it run into the sink.
2. Check for any leaks around the drain assembly, drain pipe, or trap.
3. If you find any leaks, tighten the slip nuts until the leaks stop.
### Tips
* When choosing a new drain assembly, make sure that it is the correct size for your sink.
* If you are not sure how to measure the drain pipe, you can use the old drain pipe as a guide.
* Be careful not to overtighten the slip nuts, as this can damage the drain assembly or trap.
* If you have any questions or concerns, please consult a qualified plumber.
### Troubleshooting
* If the water is not draining properly, check the drain pipe for clogs.
* If the drain is leaking, tighten the slip nuts until the leaks stop.
* If you cannot stop the leak, you may need to replace the drain assembly or trap.
