Removing the Old Drain
Step 1: Turn Off the Water Supply
Before you begin, be sure to turn off the water supply to your sink. Locate the shutoff valves under the sink and close them securely. If you don’t see any shutoff valves, you may need to turn off the main water supply to your home.
Step 2: Disconnect the Drain Lines
Once the water supply is off, disconnect the drain lines. Use a pair of pliers to loosen the nuts that connect the drain lines to the drain flange. If the nuts are corroded or difficult to remove, you may need to cut the drain lines with a hacksaw.
Step 3: Remove the Drain Flange
The drain flange is the metal plate that holds the drain assembly in place. To remove the drain flange, you’ll need to remove the bolts or screws that secure it to the sink. Be careful not to drop the bolts or screws down the drain.
Step 4: Remove the Old Drain Assembly
Once the drain flange is removed, you can remove the old drain assembly. The drain assembly consists of the drain body, the tailpiece, and the stoppers. To remove the drain body, simply lift it straight up out of the sink. The tailpiece and stoppers can then be removed by hand.
Cleaning the Drain Hole
Before installing a new sink drain, it’s crucial to thoroughly clean the drain hole to remove any debris or obstructions. This step ensures a proper fit and seal for the new drain.
Step 1: Gather Tools and Materials
You will need the following tools and materials:

| Screwdriver | To remove the old drain |
| Sponge | To wipe away debris |
| Cleaning solution (optional) | To dissolve organic matter |
Step 2: Remove the Old Drain
Using a screwdriver, unscrew the old drain from the sinkhole. Be careful not to damage the sink or surrounding area.
Step 3: Plunge the Drain
Fill the sink with a few inches of water and place the plunger over the drain hole. Plunge vigorously to dislodge any loose debris.
Step 4: Use a Wire Snake or Drain Auger
If the plunger fails to remove the obstruction, insert a wire snake or drain auger into the drain hole. Slowly snake the tool through the pipe, rotating it to catch debris. Once you feel resistance, pull the tool back to remove the obstruction.
Step 5: Flush the Drain
Run hot water through the drain for several minutes to flush away any remaining debris. If desired, you can use a cleaning solution mixed with hot water to dissolve organic matter.
Step 6: Wipe Away Debris
Use a damp sponge to wipe away any remaining debris or cleaning solution from the sinkhole and surrounding area. This will ensure a clean and secure installation for the new drain.
Installing the Drain Body
1. Clean the Sink Hole
Thoroughly clean the sink hole where you’ll be installing the drain body to ensure a secure fit. Remove any debris or residue that may hinder sealing.
2. Apply Plumber’s Putty
Mold a small section of plumber’s putty into a snake-like shape and wrap it around the base of the drain body. This will create a watertight seal between the body and the sink.
3. Insert the Drain Body
Align the drain body with the sink hole and press it into place. Ensure that the putty is evenly distributed to prevent leaks. Tighten the mounting nut from underneath using a wrench.
4. Install the Drain Washer
Place a rubber washer on top of the drain body, underneath the mounting nut. This will provide an additional barrier against water seepage.
5. Tighten the Lock Nut
Thread the lock nut onto the mounting nut and tighten it securely using a wrench. This will keep the drain body firmly in place and prevent it from loosening over time.
6. Seal the Drain Body and Nut Assembly
Apply a generous bead of silicone sealant around the perimeter of the drain body where it meets the sink. Smooth the sealant using a wet finger to create a watertight barrier. Allow the sealant to dry and cure as per the manufacturer’s instructions.
