3. Disconnect Garbage Disposal

3. Unscrew the Discharge Pipe

5. Remove Clips and Caulk
   • Loosen the metal clips underneath the countertop and cut the caulk around the sink using a utility knife.
6. Lift Away the Old Sink
   • Gently push up from underneath the sink to loosen it, then lift it out.

Step 4: Prepare the New Sink

1. Clean the Area
   • Use a putty knife to clean up any old caulk or grime from the countertop.

Step 5: Install Drain Strainer

1. Apply Plumber's Putty
   • Roll a bead of plumber's putty and place it around the drain strainer.
2. Press Strainer into Sink
   • Place the strainer into the sink, then add gaskets and flange. Tighten the assembly and clean away any excess putty.

Step 6: Install the Sink

1. Install Mounting Bracket (for disposal)
   • If using a disposal, install the mounting bracket as per the manufacturer's instructions.
2. Install the Faucet

4. Lower the Sink into Place

Step 7: Connect Water Supply
