## How to Install a Kitchen Sink Drain
Installing a kitchen sink drain is a relatively simple plumbing task that can be completed in a few hours with the right tools and materials. Here’s a step-by-step guide to help you get the job done right:
### Tools and Materials
* Adjustable wrench
* Plumber’s putty
* Basin wrench
* Putty knife
* Drain strainer
* New drain assembly
* Flashlight (optional)
### Step 1: Remove the Old Drain Assembly
1. Place a bucket or bowl underneath the sink to catch any water that may drain out.
2. Use the basin wrench to loosen the lock nut that holds the drain assembly in place.
3. Once the lock nut is loose, you can remove the old drain assembly by pulling it straight up.
### Step 2: Clean the Drain Hole
Use a putty knife to remove any old plumber’s putty or debris from the drain hole. The surface should be clean and smooth.
### Step 3: Apply Plumber’s Putty
Roll a piece of plumber’s putty into a rope and place it around the base of the new drain assembly. The putty should create a seal between the drain assembly and the sink.
### Step 4: Insert the New Drain Assembly
Align the new drain assembly with the drain hole and insert it into the sink. Press down on the drain assembly to seat it properly.
### Step 5: Tighten the Lock Nut
Use the basin wrench to tighten the lock nut onto the drain assembly. Be sure to tighten the nut securely, but do not overtighten.
### Step 6: Install the Drain Strainer
Place the drain strainer over the drain assembly and press down to secure it in place.
### Step 7: Check for Leaks
Turn on the water supply and check for any leaks around the drain assembly. If you find any leaks, tighten the lock nut further.
### Additional Tips
* If you have a double sink, you will need to install a separate drain assembly for each sink.
* If you are installing a garbage disposal, you will need to connect the drain assembly to the disposal unit.
* If you are unsure about any of the steps involved in installing a kitchen sink drain, consult a qualified plumber.
