Step 2: Remove the Old Sink
Disconnect the Plumbing

- Use an adjustable wrench to disconnect the water supply lines from the faucet.
- Remove the drain pipe and P-trap by loosening the connections with channel-lock pliers.
Detach the Sink from the Countertop
- If the sink is secured with screws, use a screwdriver to remove them.
- Cut through any old sealant or caulking with a utility knife.
- Carefully lift out the old sink and clean the countertop surface, removing any remaining adhesive.
Step 3: Install the New RV Sink
Apply Sealant and Position the Sink
- Apply plumber’s putty or silicone sealant around the edge of the sink cutout.
- Lower the new sink into place, ensuring it fits securely in the opening.
- Press down firmly to create a watertight seal.
Secure the Sink
- If your sink comes with mounting clips or brackets, attach them underneath the counter.
- Wipe away any excess sealant for a clean finish.
Step 4: Reconnect the Plumbing
Attach the Faucet and Water Supply Lines
- Install the faucet onto the new sink (if replacing it as well).
- Wrap the threads of the water supply lines with Teflon tape to prevent leaks.
- Tighten the connections with an adjustable wrench.
Reconnect the Drain Pipe
- Attach the drain pipe and P-trap to the sink’s drain opening.
- Ensure all connections are tight and properly aligned.
Step 5: Test for Leaks and Functionality
- Turn the water supply back on and check for any leaks under the sink.
- Run water through the faucet and drain to ensure proper flow.
- If you notice any leaks, tighten the connections or apply more sealant as needed.
