Preparing for Installation
Turn Off the Water Supply

Measure and Adjust Cutout (If Needed)
Measure the New Sink: Measure the dimensions of the new sink and compare them to the cutout in the countertop.
Adjust Cutout: If the new sink is larger, you may need to adjust the cutout using a jigsaw. Be sure to mark the exact dimensions and cut carefully.
Install the Faucet and Strainer
Attach Faucet: It is often easier to install the faucet on the sink before placing the sink in the countertop. Follow the manufacturer’s instructions to attach the faucet to the sink.
Apply Plumber’s Putty: Roll plumber’s putty into a snake-like shape and apply it around the underside of the sink strainer.
Insert Strainer: Insert the strainer into the sink’s drain hole and press down firmly.
Secure Strainer: From under the sink, place a rubber gasket and metal locknut onto the strainer threads. Tighten the locknut to secure the strainer in place.
Setting the Sink in Place
Apply Silicone Sealant: Apply a bead of silicone sealant around the edge of the sink cutout.
Place the Sink: Carefully lower the sink into the cutout. Ensure it is properly aligned and press down firmly to set it into the sealant.
Secure Sink: If the sink uses mounting clips, attach them from underneath to secure the sink to the countertop.
Connect Plumbing
Reattach Drain Pipe: Reattach the drain pipe to the sink strainer and tighten the nuts using a pipe wrench.
Reconnect Supply Lines: Connect the water supply lines to the faucet. Use plumber’s tape on the threads to ensure a secure fit.
Check for Leaks
Turn on Water Supply: Turn the water supply back on at the shutoff valves.
Test Faucet and Drain: Turn on the faucet and check for leaks around the supply line connections and the drain pipe. Tighten any connections if necessary.
Inspect Seal: Check around the edge of the sink for any gaps or leaks in the silicone sealant. Add more sealant if needed.
Finishing Touches
Clean Up
Remove Excess Sealant: Use a utility knife or putty knife to carefully remove any excess sealant around the edge of the sink.
Wipe Down: Clean the sink and countertop to remove any remaining dust or debris from the installation process.
Final Inspections
Check Stability: Ensure that the sink is securely in place and does not move.
Test Functionality: Test the faucet, sprayer (if applicable), and drain to ensure everything is functioning correctly.
Maintain Your New Sink
Regular Cleaning: Keep your sink clean by regularly wiping it down with a non-abrasive cleaner.
Avoid Harsh Chemicals: Use mild cleaning agents to avoid damaging the sink’s surface.
Check Sealant: Periodically check the sealant around the sink to ensure it remains intact and reapply as necessary.
Troubleshooting Common Issues
Leaking Connections: If you notice water leaking from connections, ensure all nuts are securely tightened and use plumber’s tape on threaded connections.
Slow Drain: If the sink drains slowly, ensure there are no blockages in the drain pipe and that the strainer is securely in place.
Unstable Sink: If the sink moves or feels loose, check the mounting clips and ensure they are properly tightened.
Inconsistent Water Flow: If the water flow from the new faucet is inconsistent, check the supply lines for kinks and ensure the aerator is not clogged.
